okay who is going to sell me this chip
this is the other thing people don't
think about with BGA rework so you know
when they're saying the how they're
going to get into it as a way of making
money so you know they'll say you can
make money by replacing Graphics chips
and I'll say Okay shy where do you plan
to buy these chips Nvidia and
AMD but Sharky AMD and Nvidia don't give
a [ __ ] about selling to us they only
sell desktop class processors that are
retail they're not going to sell BGA
chips to laptop motherboard
why not cuzz they don't care about us
and they don't want us to fix their
products so maybe I'll get them off eBay
well where do you think the guy on eBay
got them
from Nvidia
directly oh you dumb little Sharky yeah
right they came off the back of a
[ __ ]
truck and they were all
[ __ ] you have to remember that
everything with this business is every
everything that we do is is stuff that
we're not supposed to be doing we are
all like we are all criminals we're all
these terrible people because we
actually want to make stuff work again
instead of throw it in a garbage you
know again IA try go go ahead go ask am
like go ask you know these companies hi
I'd like to buy 100 of this chip they
they're going to ignore you they're
going to ignore your email they're going
to tell you to [ __ ]
off they have no interest in seeing any
of us work on any of these products all
right so today I'd like to go over the
circumstances under which it is okay to
Reflow a BGA chipset and I'd like to
provide you with an example it's okay to
Reflow a BGA chipset if you believe that
there's an honest chance that liquid got
under that BGA chipset and that there's
corrosion that's keeping it from working
even if it's a flip chip design it's
okay if you really firmly believe that
there's water that got under it so for
example over here we're going to be
looking at a board where I am very very
certain that liquid got on this this
area of the board so on the other side
of the board right in this area you
could see that I was doing some work by
some of the sensor ic's and I've went
gone over what these do in the video on
Apple supporting planned obsolescence we
went over the sensors now I know that
liquid got on the edge of the board and
I'm having an issue when it's booting
what it's doing is it it turns on so the
machine turns on and then it just goes
nowhere so a little white light comes on
and the fan spins but it's just blank
and this often happens when you have
corrosion under the mCP or this CPU so
let's go over a little hint that tells
me that it's not a failed BGA chipset
but rather corrosion so when you go next
to the PCH over here and I zoom in what
you're going to see is that there's a
big spot of
corrosion and what what happened here is
this actually got ultrasonic so this has
already been through an ultrasonic
cleaning process but that's still there
which means that there was probably a
lot more before the ultrasonic cleaning
process so what I'm going to do is I'm
going to make sure that I clean off all
that little Edge bonding stuff that I
took off and then I'm going to Reflow
the chip because this again this is one
of those very very few times where you
can actually Reflow a BGA flip chip BGA
chip and not feel guilty not feel like
you're ripping somebody off with
something that's going to fail again so
what do I mean when I'm talking about
reflowing BGA chips sets and them
failing so it's become very very very
common practice in our business to
Reflow a graphics chip because people
think the problem is in the solder balls
and the reality is that the flip chip
design has failed on the inside from
ridiculous amounts of heat cycles and
physical damage and all sorts of other
nasty stuff so what people will do is
they will heat the chip and they'll
think since they heated the chip and it
worked again that the problem was the
solder balls and in reality the problem
was inside the Chip And I talk about
that a lot on this channel I talk a lot
on how reballing is [ __ ] and
reflowing is [ __ ] when it's applied
to those problems because you're it's
again in those cases it's not an issue
related to solder balls so what I'd like
to do today is I'd like to show you how
how I use the zomo here to perform a
Reflow on on this and you'll get to
watch everything as I go so let's just
set this up so that I can make sure you
everything is actually visible there so
I can actually see what's on open
broadcaster so we're going to turn on
the zomo
here and we're going to get set up and
ready to go so let's just get this ready
so I'm going to put I'm going to loosen
up all all these ends
here
yeah my office is a mess today it's
absolutely
disgusting shamefully disgusting so we
are going to move this into place in the
Z and you'll see once this is done this
will work so right now again what it's
doing is it's booting to it his black
screen does absolutely
nothing nothing that
sucks okay so I see I I what I do is I
actually take out this this Optical
camera over here I'm not actually using
it to align the chip what I'm doing is
I'm using it to align this so see the
blue is the top and the Orange is the
bottom and that's the nozzle in the
middle for the pickup so what I want to
do is I want to get this aligned
perfectly so just so that the nozzle is
right over the chip and it's heating it
properly what you want to do is you want
to avoid this issue that a lot of people
run into where one side of the chip gets
heated more than the other and it
doesn't fall properly or it doesn't sit
properly that's an issue that I'd like
to
avoid now what I'm going to do is I'm
going to adjust the BGA rework camera
and since I don't have three inputs for
capture I'm going to unplug the
microscope and plug and plug the [ __ ]
uh the BGA rework camera into
that all righty
no need to buy another one of those
things for no reason so let's get over
to that Optical camera not Optical
camera the BGA camera so first things
first over
here going to plug it
in it should turn on any second now here
we go it turned on now let me just get
this set up so that it's full screen on
my on my 4K screen instead of the small
monitor see you
tomorrow and let's find some
balls okay that
is
now I'm going to take my Kester 951 flux
over here we're going to shoot that
under what this does is it's flux but
it's it's not like the amp Tech stuff
which is all goopy it'll get under the
Chip it'll flow all the way through the
other side and that's what I'm looking
for
here okay we've got it all on the chip
now I'm going to get the air filter
ready because this stuff is [ __ ]
poison
health is very important to
me ker 951 is some genuine poison right
there so I'm not going to solder with
that crap without an hour
filter
you may ask why don't I have a second
air filter for the BGA machine and if
you watch this channel you you know that
99% of the time the BGA chip is not the
problem when it is the board often
really isn't worth it
anyway and all the BGA problems there
are like Graphics chips the ones that
are really common are recalled by Apple
anyway so it's not worth it for me to
bother and the second thing that I'm
going to do is I'm going to take this
this uh air King fan that I have here
it's a few th000 RPM foot long fan and
I'm going to put it in my bathroom
window here and that's going to be my
exhaust so I have the air filter I mean
not I have the air that uh fume
extractor which is going to suck up all
that stuff I have the air conditioner
working which is going to bring new air
into the room and then I have this this
fan over here which is going to be again
it's like a few thousand RPM 12in fan
very strong fan and what that's going to
do is that's going to exhaust all this
garbage right out the window again this
is a small room it's not perfect for
soldering by any means and I know that
it's not perfect so what I'm going to do
is I'm going to do everything that I can
to make sure that I'm not breathing that
crap in or leaving my staff to breathe
that crap in because I have some basic
level of respect for them so that's
good by Jess made me sick boo
okay so we have the AC going there we
have this fan let's get this fan
on we have a fume
[Music]
extractor
[Music]
and this is where we need some
[Music]
patience
this is a really good camera so I got
this camera from David at Advanced
rework so if you're wondering why it is
I have such a perfect view whereas on
your BGA machine it looks like bull crap
it's because you have the camera that
came with the machine and the cameras
that come with these machines are
unfortunately complete another garbage I
know these machines are 2,000 3,000
$7,000 $112,000 and for that amount of
money I know you'd expect the camera to
not be a piece of crap but unfortunately
they are and you know I've talked about
this for a long time and people are like
you know you're spoiled that's
ridiculous I don't even do BGA rework
with a camera I don't know what you're
talking about and again if you're doing
BGA rework with a crappy camera fine if
you're doing BGA rework without a camera
again my hat's off to you you're better
at this than I am congratulations but
I'm not going to do this stuff without
seeing what the [ __ ] I'm
[Music]
doing I have no desire to do this
without being able to see what I'm
[Music]
doing they got that nozzle really close
on the chip it's right before touching
it
so it's really close in it's
concentrated that nozzle is almost a
perfect fit for the PCH goes ever so
slightly outside of the boundaries of
the chip which is exactly what we
want now the thing is you can set up a
basic profile you should have a basic
profile for whatever it is you're doing
but you have to realize that that is
going to change with different boards so
different boards that are at different
temperatures and you know different
weather conditions in your room when
you're working the machine may work a
little different that day these boards
are all different sizes they have
different areas of of heat absorption
you know I did a did a retina the
a1425 a little a little earlier and that
machine wound up melting a good I would
say 1 minute before everything else so
what I do here once I see that the balls
have melted and I what I do is I count
for about 20 seconds because I need the
middle balls to melt in the chip that I
can't see so I set up the stopwatch
about my phone I reset it so once I see
those balls start to melt and again this
is where the really good camera comes in
because I can see the precise moment at
which they melt once I can see that
they've melted I hit start cuz you know
again people mess around with thermal
couples on the board they have to tape
their thermal couple here or tape their
thermal couple there the way I see BGA
rework is the same way I see hot air
people always ask me what temperature
you using your hot air rework station
what temperature you using your Hackle I
have no idea there's a dial from 1 to 8
and I use what works on that board and
every board in every different area
these different boards are going to have
different areas in which they work and
it's just something that you kind of
learn as you go and same thing here I
have a profile that I set up that you
know it works based on the you know the
proper can
standard accept what is
it some ex you know best practices for
BGA rework and I set up a profile that
goes along to that so you have a little
thermal couple on the board and you see
where you know it stays at this
temperature for this time that
temperature for that time that
temperature for that time so what I did
after that having that profile is I
added a second stage to it where it
stays on for about 10 or 20 Celsius
above for another 20 or 50 seconds and I
stop it manually if it finishes the
profile sooner than it was supposed to I
stop it if it takes longer then I let it
go longer but I'm not going to run it
according to one static profile you're
going to find even if you set up one
exact profile that every now and then
it's going to be different and you have
to also consider the fact that you're
always working on different boards so
let's say you get a different board to
work on are you going to buy a profile
board for that board and then take 2 to
6 weeks to set up an exact profile is
that how you plan to be profitable
that's not profitable that's not
practical that makes no damn sense what
makes sense is here we go so it's
starting to melt you can see on the left
it's starting to melt let's wait for the
right to
melt okay the balls on the right side
have melted so now I'm going to give it
10 seconds from the point of every ball
melting so that I can ensure that I melt
the center
balls the PCH is a particularly
sensitive chip so I'm not going to keep
it melted very long okay so 23 seconds
now I'm going to hit
stop now I'm going to do manual cooling
I'm going to turn the nozzle up here so
that it cools down a little faster even
going to help it along a little with
a yep like blowing out a birthday
cake that didn't do a damn thing that
was dumb
it's here we go everything everything is
starting to
dry so it looks like we've spent a total
of 56 seconds with the balls in a liquid
state where you know you could clearly
tell that they were no longer
solidified which is a little longer than
I'd like to spend on a PCH because a PCH
again the PCH is a very very sensitive
chip this one is very very easy to kill
with excess heat it doesn't respond well
to excess
heat so we're just going to let the
board cool off for a little
[Music]
bit and again it's going to be by feel
so this is a profile that I usually run
for 350 seconds we're 314 seconds into
the profile and it melted and you know I
didn't expect that that's not how it
worked the last time I worked on this
motherboard but that's how it worked
this time so that's why it's important
to see it because again you you can know
you can have a little thermal couple
next to your chip all day long and you
can watch that little temperature sensor
all day long and still have absolutely
no idea what's actually going on when
you're working on that chip you know
yeah you have to see what's going on at
least that's my opinion again there are
a lot of people that get by not doing
that but I
can't by the way to get rid of that myth
that everybody keeps trolling with that
says I have a boner every time I wear
these specific set of pants it's the way
the pants fold
see you you can just pop it back and it
see now I went from having a boner to
having a vagina are you happy [ __ ]
trolls so let's
see so we're just about to a point where
the board is kind of cooled
off I can turn off the
filter since the zmo just ran the my
room is a little warm now so going to
turn on the
AC I can turn off the exhaust since I
don't that's how I turn off the exhaust
I flip the light switch in the bathroom
and I swing the the exhaust door
shut
okay now we're going to enlist the help
of
Sharky hello
Sharky
hello how was your day Sharky good until
you burn the roof of my mouth
again I'm sorry to hear that
Sharky so now what we're going to do
we're going to see if this can Boot and
see if it does anything so again before
we would turn it on and you would get a
black
screen so it would turn on but just
doesn't do anything and we get stuck at
that
point ah ah down
here okay I'm just clean getting off the
heat sinks so I have a napkin that's
half dry and half alcohol on the other
side so I first I remove all the junky
part the dry part of the napkin and then
I use the alcohol part of the napkin to
ensure that there's nothing left and
there's no
residue nice try to get away fan but you
don't get
away
the one thing I like about the
articulating stand one of the very few
benefits of this you know because again
what the thing that drives me nuts with
the articulating stand is that this
thing is always moving
around like while it's shaking on the
desk and jiggling while I'm working
drives me nuts but the one thing I like
cuz I can push it away and then increase
my real
estate which here is you know important
cuz I I have no [ __ ] real estate
let's get some thermal
paste
now if it works the same the issue is
probably something else if it doesn't
work at all it means the chip set itself
is actually dead and this is not related
to corrosion and that the chip needs to
be replaced because if the chip is if
you get a change after heating a chip so
let's say you get a change where it dies
then you have a bad chip and and if it
works then most likely my theory was
correct and the corrosion was got under
the chip you know the corrosion got
under there that's where that green junk
that we saw
was so let's see what we get here I
didn't put this the bottom speaker in
because I don't know if this actually
works yet I may have to take the board
out
again I should put the bottom speaker in
because that would show a level of
confidence that would make this thing
work wouldn't
it that would be cool that would that
would be the smart thing to
do I need to exert confidence show this
board who's
boss
dead totally dead so okay I was wrong
bad chip hey sometimes I'm wrong
sometimes I'm wrong so let's remove that
chip and put a new one on shall
we so we went from a machine that turned
on but couldn't do anything to a machine
that was
dead and the PCH is responsible for many
of the power functions in the
machine I hate BGA
rework all right
Mall
my
[Music]
for
[Music]
all right let's get that ship off of the
boy
for
[Music]
I
[Music]
liquidous at 216
C this chip melts real
[Music]
easy just put some pressure on it so I
can tell when it's fully melted it'll
kind of get squished down a little
bit
ah here we go you know how rare it is
that this feature of the machine
actually works and it sucks up the
chip so we stop the
profile manually now I'm going to put
some flux on the board let's just turn
off facial focus in this camera so that
it autofocuses properly
now the camera's kind of far away so I'm
not sure how good this is going to look
if it's going to look that good at
all let's see what it
gets this is as far as that camera will
Zoom from the other side of the
room yeah you can't see [ __ ] oh
well but what I'm doing over here is I'm
just I'm going to run a Leed solder ball
with a bunch of this amtech 559 here
over there and that's going to make it's
going to get rid of a lot of the
junk and you know the nasty
old mucked up old let it
[Music]
solder it's going to make it easier to
remove the lead the the solder if it's
leaded than lead free so I run the
leaded ball all over and it's just going
to pick up all the lead free [ __ ]
make sure to not let it touch any of the
resistors in the
side knocking those off will make this
job a
nightmare and again it's easier to do
this while the board is actually hot so
if you're going to do something like
this it makes sense to do it while it's
on this machine where the board itself
is hot then to try to you know heat up
all these solder balls while the board
is freezing sitting on the
[Music]
table all right now we're just going to
wait for it to cool off for a little bit
turn off that iron that iron B over
there is the hacko
936 it's not the best thing in the world
it's actually a 936 station with a
knockoff iron I got to replace the
broken original it's sit there it's l it
has no use in this world other than
running a blob over to pick up a bunch
of balls it's not used for anything of
precision so I just set it next to my
old machine instead of throwing it in
the garbage just sits next to the BGA
machine just to make that one little
process
easier all right so it's going to take a
few for that thing to
cool yep that's my office that's my
beautiful
office that camera over there is not
plugged into anything I should actually
I should really remove
[Music]
that let's see what temp where we at
okay we're low enough that I'm not going
to burn myself so machine can go off and
I just dropped the chip onto the
board [ __ ] that was
[Music]
dumb turn off the
filter
wait I'm wearing sh Sharky and I'm
taking it off with the other hand Sharky
you tried to trick
me
yes okay you take the filter back over
we're going to
clean cleaning is
important and so is
filtration if I made any real money off
a BGA rework I buy another filter but
I'm not going to spend like 500 bucks on
a hacko fa
430 for it's a beautiful filter I'm not
saying it's bad I'm just I'm not going
to spend on it for something that I do
you know like once every two weeks
doesn't make my friend Jake his mother
says this thing that I find funny that's
really I like the saying it's if it if
it don't make dollars it don't make
sense and I very much agree with that
saying I think it's
spoton it really speaks to my business
mentality it don't make dollars it don't
make
[Music]
sense you probably won't get to see much
here I don't think you're going to get
to see much because the uh this this m
this microscope only goes down a 7x and
you kind of need something like 3x to be
able to see the entirety of a BGA
chip let's just plug the microscope back
in let's see if you can actually see
anything as I'm
[Music]
working yeah you can't see the whole
chip and the camera sees even less than
what I see
so you'll just have to live with
[Music]
it so we're going to get rid of all the
old
[Music]
solder first we're going to clean off
this thing so I'm not putting new solder
in my damn
Wick that I'm using to remove the old
stuff I have hacko at 599b and I forget
to replace it very often so I wind up
using it's it's like I'm using
um I it's more solder on the uh on the
tip when I take it out of that [ __ ]
thing than there is before I put it in
there Sunny pointed this out to me and
was nice enough to give me his which I I
very quickly you know
ruined I laid waste to
it again so when you're going around the
sides it's good to bend the wick like
this see what I'm doing so I'm not
hitting the resistors it's not good when
you when you like whoops you know you
should bend it like this so that you're
not hitting the resistors on the side
it's going to make the rework process a
lot easier and you don't have to push
hard I'm not pushing hard on this Wick I
don't want to take every single pad off
of the board that's not my goal
here okay we're going to cut it off now
move it to the
side same thing
see I missed a couple of balls on the
corners we're going to get
those it's going to be easier to get
those because I'm at a different angle
try to go over all the stuff that I
missed what's going to get missed is
usually the stuff by the
[Music]
corner I'm never going to lift the iron
without lifting the wick along with with
it that's an important part of clicking
these BGA
pads okay now we're going to clean this
disgusting
garbage
so I'm going to we're going to grab a
clean room wiper and I'm not going to
use a paper towel here I prefer to just
not have to clean dust off of the bottom
of the
chip wrap it around a few times take
some
alcohol and this is the gross part you
don't want to use a paper towel here cuz
the thing is that that flux that's
inside that I use and also the flux
that's inside of the gute wick that I
use by the way if you notice that my
wicking seemed a lot easier than yours
it's because I use gut Wick which is
good stuff whereas you're probably using
that stuff that says solder Wick in
white writing with a blue backdrop that
you get on eBay or Amazon that's total
[ __ ] garbage guess how I know guess
how many pads I ripped with it and yeah
not good stuff running wires to chipsets
because you use bad weight Wick sucks so
anyway see I forget what I was talking
about before that but yeah here we go so
that's that's my that's my BGA
site there that looks much more natural
on the camera now than it did
before this is my BGA
[Music]
site looks pretty good
[Music]
right you can see there's a lot of those
probe points that are kind of reddish
brownish which makes me wonder if maybe
some over voltage went to my PCH and
killed it or who
knows so we really get in there and
clean it
[Music]
good didn't knock off any resistors on
the side that's
good that little cap could use touch up
I'll touch it up later
on
[Music]
okay so I'm I'm satisfied with this so
now what I have to do is I have to get
this on the BGA rework machine I should
actually put some flux on there first
let's just make sure I've gotten rid of
all the alcohol with the hter station
here alcohol is gone all right so now
I'm going to take another clean room
wiper we're going to add some
flux get my mtech 559 over
here usually I would use a a specific
flux for lead versus lead free I'm doing
something that's not best practice here
cuz you know they make they make them
for specific materials
but there's not much I can do at the
moment me just draw it on there fold the
clean room wiper over so that the flux
doesn't get onto my finger because that
that would be
gross and then just kind of rub it on
there and the great part about the clean
room wiper versus the paper towel is but
how abrasive this flux is and how
abrasive the wick flux is you're go it's
going to have a lot of [ __ ] stuck to it
like it's going to rip all those little
fibers off of the napkin real
easy and that's going to be really
miserable to work
with
okay now the most important thing forgot
the orientation of the [ __ ] ship cuz
it fell off of there damn it so what I
have to do now is yeah let's just look
at another board get the orientation of
it
okay I for
yeah okay I got it orientation
beautiful okay turn off
this oh I have to plug in the BGA camera
not the microscope one
okay switch let's see how fast you
switch I am not impressed I am not
impressed wait it did switch you just
can't see anything cuz the lights off
duhh I'm not impressed with how dumb I
am either so okay let's get this on the
BGA
machine and be D repairs are such a
[ __ ] waste of
time they really like they suck up
inordinate amounts of
time cuz again keep in mind this could
be a board that had something else wrong
with it because you're never really 100
100% sure with anything related to
liquid damage that you're estimate is
perfect that you were
right that there was nothing else
wrong all right so I started preparing
my chip in the oven here so I'm just
going to take it out of the
oven
set the machine to operation manual
vacuum this is the part that's going to
hurt since I just took it out of the
oven all
right let's see how far off this
is we're going to do some chip alignment
now let's get this thing off of face
facial Focus wait it wasn't on facial
Focus oh great so now is out of focus
the whole video
lovely I don't have an SDI capture
Hardware so that uses regular composite
or something and I don't have capture
hardware for that so this will have to
do I know trolls it's not perfect it's a
[ __ ] camcorder pointed at television
but what do you want all right
so this is way way
off you may have noticed in the
background that my phone never stops
ringing like never so I mean if you're
one of those people that's called in
saying hi my pp3 v42 is missing and I
was wondering if Lewis was there to give
me a consultation like you may realize
this is why I I actively ignore or troll
those phone calls cuz like really that
that phone never stops ringing it's
never ever stops ringing there's always
something and do you think that I am
going to spend time explaining over the
phone how to fix a board for free when
the phone rings every 9 seconds
no like the people here answer the phone
that their work is literally it's never
done I
mean all right let's get this into
place this is probably painful to
watch I'm just moving the things around
here so that I can get it into
place so once it's like approximately in
a place then you can then I then I
tighten these these standoffs that go
into the board screw holes and then from
that point I can use the fine controls
on the machine to actually get this in a
in a place
perfectly this is so far from being
perfect though so let's we got to
twist
it doesn't help that nothing in
Manhattan is
level let's zoom in and see what it
looks like in the
middle let's get some more blue
light blue light is going to be the
chip so now that the middle is good the
sides look a little
better all right and
ultimately seeing how it actually lands
is what going to be what tells me
whether this job is good or garbage so
wish me
luck
so so it looks like they've landed on
the pads I'm going to hope that they
landed on the pads because hell if I can
really tell from with when the flux is
there it's hard to
see time to move the air filter over and
get my profile
started
[Music]
okay
[Music]
let's just get it set up so that this
more directly under the
nozzle just moved it over a little
[Music]
bit adjust the focus of the camera to
match
that also since this is kind of a really
easy to kill chip I'm actually going to
lift the heater up off of the board a
little bit so I'm going to have the fan
on sevens on maybe six yeah six and a
half for top air flow
[Music]
adjust and we're going to have this just
a little bit off from the
board nozzle
[Music]
there I should have my stopwatch ready
as
well
[Music]
so that's not solder melting that's just
flux moving
around now we're at right now 130 C once
it hits 145 to 165 see the temperature
of the board is usually lags the
temperature of the hot air by about 20
Cel so once that hits 140 or 160 on the
machine you're going to notice the flux
starts to activate when the flux starts
to activate you're going to be able to
see the the pads much better than what
you can see right now because right now
you can't really see the pads for
[ __ ] cuz the flux is over
[Music]
them
okay so we're up to 205 Celsius in the
top and since we're just about to enter
the stage
wow see this is what kills me
is this I got this chip off eBay which
is pretty much the only place that you
can get a lot of this [ __ ] so why is
supposedly new chip with lead free
solder
melting at at 200 C which is 180 which
is what Le it would melt at see that's
probably happening because this chip is
some fake ass rebol
[ __ ] what you going to
do so I'm pretty happy with
[Music]
that
[Music]
assisted in
drying that's the air
[Music]
filter
[Music]
all right now we just wait for it to
cool
off this board is probably some that
ship is probably some reball
[ __ ] either a gremlin crawled inside
my zmo and has has it so that the all
the temperature readings are 50 CSUS off
or what I bought off of eBay was reball
[ __ ] you may be wondering well louw
you say you don't like eBay LS why would
you buy this off of there it's like okay
who is going to sell me this chip this
is the other thing people don't think
about with BGA rework so you know when
they're saying the how they're going to
get into it as a way of making money so
you know they'll
say you can make money by replacing
Graphics chips and I'll say Okay Sharky
where do you plan to buy these chips
Nvidia and
AMD but Sharky AMD and Nvidia don't give
a [ __ ] about selling to us they only
sell desktop class processors that are
retail they're not going to sell BGA
chips to laptop
motherboards why not
cuz they don't care about us and they
don't want us to fix their
products so maybe I'll get them off eBay
well where do you think the guy on eBay
got them
from Nvidia
directly oh you dumb little Sharky yeah
right they came off the back of a
[ __ ] truck and they were all
[ __ ] you have to remember that
everything with this business is
everything that we do is is stuff that
we're not supposed to be doing we are
all like we are all criminals we're all
these terrible people because we
actually want to make stuff work again
instead of throw it in a garbage you
know again IA try go go ahead go ask am
like go ask you know these companies hi
I'd like to buy 100 of this chip they
they're going to ignore you they're
going to ignore your email they're going
to tell you to [ __ ]
off they have no interest in seeing any
of us work on any of these
products
so we're going to do a little bit of an
inspection to see how the BGA process
went just plug the microscope back
in to the capture Hardware
no
for
I shake too
much stop shaking
[ __ ]
all right so before I bother putting a
heat sink and all that other crap
on you know do I get my favorite thing
in the world
do I get a fan spin because I would love
to see a fan
spin I get a fan
spin okay now remember the original
problem with this board was black screen
not booting into anything don't get
excited yes done y dumbass you still
have work to
do now remember we re replace the PC on
an on a core ier platform which means
that we now have to flash an SPI ROM
with a clean Emy
region remember the PCH is not going to
properly speak to the SPI ROM and the
SPI ROM is not going to properly speak
to the PCH on any of these core I series
platforms if the EM region is the one
that is used for the the old PCH so what
we have to do is Flash an SPI ROM with a
clean me
region so that's what's coming up
next that takes [ __ ] forever you have
to use this little bios programmer that
I have and oh my God it is [ __ ]
slow like writing 8 megabytes you'll see
you wait till you see how long it takes
the right eight [ __ ] megabytes
so I'm going to close out of all the
junk that I have
opened so I have a lot of windows open
here a lot of
Windows
yikes oh I'm never going to see my
desktop at this
rate
wow
finally Sanctuary so you'll see that
I've already actually it looks like I've
already done bios on here just to see if
it was a bios issue or a PCH issue
before moving forward I can tell that
from what I see on the screen so on the
microscope so yeah see see this looks
like I've already [ __ ] with it
so here's what I'm going to do take that
off so I get my BIOS program here which
is a mini proo it's a tl866
a first if I'm going to be doing more
soldering let me just bring the fume
extractor back
over okay
you may ask why I put the fume extractor
in this inconvenient space it's because
I can hit I can hit the onoff switch
with my foot so I I get driven nuts by
this thing when it's on it high all the
time because it's a loud annoying noise
so I want it to be someplace where I can
easily switch the settings from low to
high and I also want to be able to
instantly kick it off it will be nice
and since thing cost $600 [ __ ]
dollars if it came with something like a
a foot switch hint hacko hint how to
design a product that's less
annoying the the uh the FR A10 makes it
obvious that they don't care about
designing a product that's less annoying
you know I mean really who wants to use
that alarm clock setup with the the
[ __ ] pound key you got the pound key
and the the asteris key for setting
temperature instead of a standard system
I don't understand that at
all that that is so [ __ ]
counterintuitive for no good reason so
first thing I'm going to do here is I'm
going to desolder the SPI ROM chip
from the
motherboard now I'm not going to get an
Emmy region cleaning here because that
this video is going to wind up lasting
all day but the thing is you have to
have a an SPI ROM that has a clean
management engine
region so I already have one that has
that you can find these on forums online
if you don't know how to do
it and there there that's going to be
finding that is going to be your
adventure since i' I've kind of given
away enough information as it
is
so I have one of those so instead of
having to go not cleaning Emy regions
I'm just going to flash one that I know
has a clean em region so you ever log
into an SSH server you know when you log
into an SSH server how it says something
like uh you know it is a key that that
that's uh presented there's a handshake
that occurs and then let's say you
change that SSH server so you you
reinstall the operating system on it and
then your CL the client PC tries to
connect to it again it'll say something
like warning you know different hash and
that the whole idea behind that is that
it you'll know if it was compromised the
same thing is true here with the PCH it
does the exact same thing with the SPI
ROM chip so anytime you change the PCH
you have to get a clean em region
anytime you change the BIOS chip you
have to have a clean em
region so let's go over this come on
heat up heat up EO heat up all right
hasn't beeps but I know we're close
enough
all
right zing
[Laughter]
zing ah that was bad focus on the
microscope
there sorry about
that all
right
this is a tl866 with an adapter that I
bought off of Amazon it's the one on
Amazon with Amazon Prime it's sold by
soyi or sukii or Sundi or something like
[Music]
that oh boy nice job that makes me very
happy and excited so now we plug this
thing in to the
programmer so we're going to plug the
programmer in via USB 2 I'm pretty sure
this [ __ ] works on USB one speed so you
choose your chip over here MXL
6406 so I type
in
6406
e so p8 that's the package I'm going to
load the bios for this
machine I'm going toit program it set to
check the device ID which it already did
over up here it says actually it didn't
say chip ID let's see if it finds the
chip it's going to erase before it
flashes and verify after so it must have
gotten the chip yeah the ID c227 so if
it doesn't get the chip ID it means you
have not done it properly means you
haven't slded it properly you chose the
wrong chip or the chip you're using is
[ __ ] up or you shorted the pads
so anyway look this is pretty much how
long it takes for it to ride an 8
megabyte file eight [ __ ] megabytes
all day so I might as well just get the
board prepared in the meantime while I'm
waiting for this [ __ ] which means
just putting some solder back on the
pads for the BIOS
chip see again that that phone that it
just Rings mercilessly all day so it's
not that I hate you it's not that I wish
you harm but you know when you have
have when you call in with those like
with free with free help questions again
you got to realize that this is a
business and that's business
[Music]
time see they just weren't able to pick
that up because they're already on the
phone with a bunch of people why I deci
had to pick it up and transfer to them
since I'm doing the damn YouTube video
but it's like you know it ain't that I
don't you know it ain't that I
personally hate you it's just business
time is business time and during bus
this time I have no ability to deal with
you if you're not a customer it's just
not being mean you know I just can't I
can't help
you cuz if I if I help you then I can't
help all those other people that keep
calling nonstop all day that actually
have the desire to become a
[Music]
customer okay so the programming was
successful so now I'm going to might as
well just put the heat sink back on the
board we're going to see if I can get
into an operating
system is BGA rework a waste of [ __ ]
time or what I mean this is clearly
breaking the 20-minute rule like really
really breaking the 20-minute
rule
[Music]
and again this I could do the all this
[ __ ] and there could be something else
wrong with it that's not worth
fixing I mean again if you're under that
idea that BGA rework is the real money
maker and you can't fix motherboards
without a BGA machine you know I'm here
to tell you that that's a bunch of BS
I'm also here to tell you that most of
the mother at least if you're working on
the same line of products that I am if
you're working on this line of products
the money is not in having a BGA
machine if you have it because you have
a way of doing business where this makes
you profitable by all means continue
doing it more power to you but if you're
just getting into this as a
craft you know BGA rework is not where
your money's going to be so anyway I
figured out why the PCH was bad last
time it was a lack of confidence
remember when I said I didn't put the
speaker on because I wanted to make sure
it works first well this time not only
am I going to put the [ __ ] speaker on
I'm going to put the the adhesive strip
on it so that it stays in the
machine That's What I Call
confidence they're going to show this
[ __ ] who boss we're expecting you to
work you're glued
together there are these strips that
keep the speaker adhesed in and those
wear out with time especially if the
machine was Liquid damaged and liquid
gut on your adhesive so I I I'm going to
put a new set on there's nothing worse
than when a customer gets the thing back
and the speaker rattling it's like you
fixed it and yeah you're right that
complaining about that tiny little
reassembly error is something that's
Petty but at the same time when they're
going to notice that and even if they
don't complain even if they have it in
them to not complain because they needed
a lot of work to get this stuff to work
again they're going to notice that and
that's going to make them not really
want to come back to you or have
something fixed in the future and the
whole point of this Channel and the is
to encourage repair opposed to you know
destruction and throwing [ __ ] away and
letting Apple get you know a couple more
hundred billion dollars off of ripping
people off and that's that and that's
going to come from doing the job
right so let's take that bios chip with
the clean Emy region and put it on
here
[Laughter]
I'm getting on Ah that's
awful
that's absolutely
awful worst solder joints in the
world oh there's good solder down there
all we have to do is make it into a
proper
joint that's where the elbow of the
curvy tip comes in so wait for it to
beep
okay this winds up passing ASD I can
always ultrasonic this thing
later okay Moment of Truth
time nice try microphone come back here
all right
does this work or was all of this a
waste of [ __ ]
time now I can't choose an alternate OS
to boot into because cuz I think this
thing actually has a bad keyboard so I'm
just going to take the original drive
out and just put mine in which has just
a fresh it's an SSD with a fresh
operating system I have no patience for
waiting for a hard
drive so original issue no not booting
into OS then no no picture on the screen
and no
chiming now let's see what I get so what
do you think think I'm going to get any
faith think it'll
work or do you think this was all a
waste of
time what's your
opinion here we go green light fan
spin and
beeping okay let's try a different
memory
stick
let's try a different memory
slot and this machine can eat [ __ ] and
die yeah that's that's that's that
that is
that that is
that this is why this is a BS thing to
do cuz these chips that you get these
chips that you get are total bull
crap just complete and utter
horseshit not much else to
it so I'm going to wash my hands from
the
flux
H actually turned on and decided to
start booting check this
out so before we had a black screen and
no beeping that was my original symptom
now It beeped and then out of nowhere
decided it wants to
boot
but it won't
boot
it really sucks that there's no
legitimate sources for a lot of these
chipsets like even if I wanted to spend
50 bucks to get a known good chip excuse
me by the way even if I wanted to spend
$50 if I wanted to be 50 bucks right now
to give me a good ship not just like buy
the cheap crap that's out there there's
not an option like I I cannot say you
know hi interel hi Intel hi AMD hi
Nvidia and buy something good cuzz I'm
pretty damn sure that my diagnosis here
was correct and I'm very very confident
in my reworking process you can see my
BGA rework process in some of the older
videos I've done and you can also see
you know and you can see what the boards
look like afterwards so I actually show
you the way everything on the board
looks afterwards around the chip and
around the area and you can see that
what I do for the most part is neat good
quality
work but yeah what happens with a lot of
with a lot of these chipsets is they
they come like they're just complete
pieces of
[ __ ] that's China for you so not much we
can do here this one goes in the trash
