all right let's see this board thank you
for coming by
good night ESD safe tap right there
I have to get a smaller keyboard
I have to get something to put this
keyboard on I can't wait for my desk my
real desk to arrive this is my small
desk this is kind of a dump dumpy desk
okay so the first things that I let's
see so what do you have here what is
what is going on with this so it's just
a mod chip on the board
um it's just a for an original Xbox I
went through and recapped it and I was
trying to install the mod chip and uh
wasn't very successful at installing the
pins
okay
there was something I was just looking
at before I hit the start button and I
forget what it was now do you remember
what I was looking at yes yes it was
right here uh okay
[Music]
okay so what was going on here with the
little hole oh this is what the idea was
you need to decider a wire to this and
while soldering a wire to that or trying
to scrape it you may have scraped this
over here okay so that's definitely
where was the what was the part you
having the issue with uh point to that
with the pins of the uh
right here it's going to be looking a
little mac Bush macbook-ish over here so
let's get some alcohol and clean off
some of that corrosion
I don't have an ultrasonic cleaner yet
but this is well the one on the upper
left is okay the one on the lower left
is acceptable but not great because you
can see like this is gonna you know
conduct this is not going to conduct
well the problem with this one is this
is completely destroyed over here so the
trace is going to this circle
but it's kind of cut out okay see that
so now Yuki this this is not the worst
thing in the world you just scrape it
away a little bit
and we'll have we'll just put our own
little jumper wire over there so what is
go what is going to go over here so what
are we putting this whole part actually
needs to come out so all those pins that
whole little pin section it just needs
to come out and I was going to clean it
back up and because I I was getting to a
point where I couldn't get the uh uh the
solder to actually for some reason it
wouldn't stick
even no matter how much flux I used I
tried not to overheat it so you couldn't
get what to stick you can get these pins
that you were saying That's from
underneath the board
let's see what's underneath here
okay let's see
can't be anything worse than what I did
in 1997 trying to model PlayStation one
okay
yeah so some of these are no longer
really pads
don't say I'm just going to clear away
some of the flux so that I could see
better
I really should put this computer out of
the way that I don't need anymore
so let's clear away some of the flux so
we could see it better
yeah like the right way to so what you
could do here is you could pull out
uh each after wicking the pads on all of
these you would then just pull the
connector out behind door number two
after you Wick everything you could use
hot air to heat it up and then pull it
out from the other side
now the risk of using Wick and
desoldering each one of these and then
pulling it out is that if there's any
solder stuck inside of there and
sometimes it's just hard to get it out
if there's any solder stuck inside of
any of those then when you pull it out
you may be actually destroying this ring
however the risk of doing at the hot air
method is heating the entire board and
you have an Nvidia chip on this side
that I would not want to overheat or
mess with because you know it's a it's
an Nvidia chip inside of a BGA chip
right next to it
each one has its risk to it and you kind
of want to manage the amount of risk
that you deal with so
I would start by wicking these pads so
let me just show you how I would Wick
with one of these and then I'll watch
you do it in the microscope
first thing I have to do is find out
where I put my iron
I think there's two irons at this desk
because one of them wasn't working when
I tried it
tackle quality control ain't what it
used to be I'll tell you that
okay so the hakko is singing the song of
its people okay that's that flux
you know we have a nice little line of
it over there
so do what you can to remove as much
solder from these pins as humanly
possible using the wick and this
also this Cutter's at that desk you're
going to use the cut the wick because
you can't use it after a certain period
you're not going to want to Wick with
that iron that's a micro pencil
you have to remove the key or else it
will destroy your thumb that's a thumb
Destroyer
yes now it's actually there to keep
people from changing the temperature in
the factory so if you're working in a
Chinese sleigh Factory where they if you
want to work for 13 hours a day instead
of 13 and a half if you raise the
temperature on the station you can get
work done faster however you'll lower
the quality of the joints that you make
that way depending on what you're
working on or you'll make less reliable
ones so in order to make sure that they
stay there for the whole 14 hours
instead of 13 hours and get off early
they put that little key there which
doesn't allow them to change the
temperature of their station so you
don't look at the screen you look to the
Oculus okay
so this is zoom you're going to want to
have the zoom all the way out there's no
reason to zoom in for this and and then
focus is adjusted by the knob that moves
it up and down on the side by yes
everybody for the people who asked we
have upgraded from our Ozarka brand fire
extinguishers that we're using
previously
to uh
actual fire extinguishers each each
student desk has a full fire
extinguisher I'm a big supporter of the
Ozarka brand of fire extinguisher
[Music]
I think those pins you're actually
pushing them in so you're not really
yeah the problem there is you're not
actually removing this Auto you're just
pushing the pin further down and getting
the solder in there so you're probably
going to wind up using the hot air
station and pulling from the other sides
from the other side you're going to grab
it with the tweezer you're going to heat
the board like up here and then you're
just going to pull it out okay
you want to be strategic about how you
use your hot air because you don't want
to melt the BGA chip on the other side
of the board that would be bad so you
want to use enough heat that you can
pull the pins out or enough a short
enough amount of time you can pull those
pins out but not enough time that you're
going to heat the any of the stuff
around you always want to heat the board
the minimum amount as humanly possible
to actually get what you want to get
done done
have you used the hot air station before
okay so we should probably practice on
something that doesn't belong to you so
you don't break try something like
removing this component this is R20
using hot air
so you pick this up
your tweezers will be your alternate
hand the hot air is usually in your
dominant hand
you click this little button over here
to turn it on you can wait for it to
heat up over here it'll tell you the
temperature anytime you put the thing
back in the station it'll start cooling
down again automatically
okay so this this is a low temperature
now the temperature that you said is
really going to be based in the board
that you're working on different boards
are going to have to require different
temperatures hey how are you different
boards yes different boards are going to
require different temperatures so you
know like a Macbook board is going to
require a lot more heat than an old Xbox
board so the 480 Celsius we're setting
here for the take that off we're not
going to use that on yours we're
probably going to lower that to like 350
or so
how are you
sure what do you have what's wrong with
it heavy um
it's a custom-made
all right cool yeah
sure have a seat
is that as blurry for you as it is for
me it is okay so then
oh okay use this for focus
I have all this all this schematics with
me and all the little pieces that go
with it all right
so what is your prior soldering
experience if any
not much I only saw like small tables
together okay oh let's see
so let's turn on this microscope camera
so I could see what you see
turn on the screen so I can see what you
see
have you used a microscope before uh no
okay so most everything that you brought
is large enough that you don't need to
change the zoom so this knob is going to
change your Zoom so like how so let's
turn the light on over here so you can
see there we go
yeah so you're not gonna have to work on
this at you know this level of zoom
we're not doing that uh you're gonna be
working all the way up here at 7x so
this knob over here is the important one
this is going to change your focus okay
so your amount of me so the first thing
that you're going to have to get used to
when using a microscope is this idea of
proprioception which is where knowing
where your body is when you can't see so
if I have my eyes closed then like I do
this I should know that my like my leg
is let's say parallel with or
perpendicular to my knee it was a
constant in martial arts so you have to
know where everything is all the time
and the same thing is true here so let's
say you're using a hot air station or a
soldering iron if you were going to use
hot air to solder something on the board
if you're looking in the microscope you
need to know that your iron that your
hot air is facing this way and not this
way because you can't see it so you have
you're gonna have to kind of get used to
that slowly so just keep that idea in
the back of your head knowing where your
hands are and try practicing a little
bit before you actually start soldering
on this grab something like a tweezer
which
should be here
unless somebody stole them last time
I'll be pissed if somebody saw tweezers
somebody stole tweezers
yeah I want you to practice let's say
looking in the microscope and without
looking outside of it tapping certain
things with this you're going to pick up
the tweezers you know the choices are
here already you know let's say take
let's put this in the microscope over
here pick up the while your eyes are in
there pick up the tweezers and then get
them to point at let's say F1
but you can't pick up the choices and
without your hands in the microscope all
right yeah so put your eyes in them
microscope is this is just to get used
to it yeah
I got two awesome problems all right
okay let's go for it now watch as you do
that because I don't want you to ruin
the Nvidia trip at some point you may
reach the point like where I did where
you're at that top of your limit here so
what I do at that point is I have to up
this
so once pick it up put this a little bit
higher
okay now there's some more now there's
some more room for you to go up or down
you're probably gonna have to lower it a
bit now
so what would you want to put on here
first so you have all the components in
the Box over there
I would imagine starting with something
simpler like
an individual capacitor
now there's two ways that you can do
this behind door number one you could
put solder on each pad over here
let me let me just watch him do that
before this okay
I would start let's see if through a
three we could do a 350.
yeah 480 is a little crazy for an Xbox
so we're gonna try to grab that thing
under there this is something you're not
going to need a microscope for to be on
like you're not pulling off a
microscopic components let's just get
rid of the microscope for this part of
it you we will use it to resolder
another one of these pins later
so we're gonna
you're gonna grab that
and I would actually instead of grabbing
it with tweezers do you is there that
little green wire cutter thing on the
desk here
or did I steal it from you
somebody donated a green wire cutter
thing very graciously yesterday
oh here we go okay so I would kind of I
would grab it with this and we're not
going to pull too crazy hard but we
because I don't want you to rip any of
this turns out
I mean I don't want you to rip any of
those pads out just grab it a little bit
and now start heating on the other side
right close to the pins and just move
back and forth between that area
and then don't pull hard just have a
little bit of pressure on it so you can
feel when it's when it's melted and then
once it's melted wait a second or two
and then pull it out
don't be like cardi B pull out game week
felia
all right so now we're gonna uh you
don't want to take your your hot air
away because then you're gonna have to
start all over again that's another
thermal cycle on the board and we want
to avoid thermal Cycles so keep it there
all right back and forth back and forth
a little bit of pull a little bit of
pull
also hold the board steady for you
there goes okay
let's see if the pullout game was strong
it does not look like you knocked off
any of the surrounding components
pull out game strong all right let's
take a look at the microscope
[Music]
okay
okay now one or two of these has you
know solder in the hole not not the
biggest deal in the world so a little
bit of Wick and the iron will fix that
one of these pads I mean it's actually
two of these okay three three of these
look hopeless to me so we're gonna have
to do jumper wires to the three that
were a little damaged from the beginning
so like this
ouch but again you said this one's not
actually used I mean you may be lucky
there
uh yeah this this looks horrid
uh you have
this one over here I'm even though this
this pad is okay like kind of okay it's
falling apart so I would probably put a
jumper wire over here I'd make a jumper
and put that to the PIN
uh this one as well what I don't know
what's going on over here
shut up phone
so let's see from the other side
so let me just lower this a little bit
also before we put a new thing on I want
to take an inventory of which pads are
damaged because some of these are going
to require jumpers from the top side and
some of them are going to require
jumpers from the bottom side
okay so like if you oh ouch finger
Do not drop a microscope on your finger
ouch
[ __ ]
uh the internal bleeding begins and that
nice little
yes
no the the nice little chemical is
starting to go through your brain that
makes you forget that you're just
internally bleeding you ever stub your
toe on something in like 30 seconds in
the pain ends and you start getting this
like natural morphine drip
okay natural morphine drip is started
Okay cool so
yes like some of these have the trace is
messed up in the bottom and some of them
haven't messed up on the top so like
this I'm Gonna Wanna I'm gonna want to
scrape away and make something for this
and for this
before we actually you know put the pin
on there
these two you're gonna have to try to
get the solder out of the hole
Futo is not an acronym
it's just four letters that sound good
together
we don't believe in acronyms here and
that rule hasn't changed
Futo is not an acronym
Futo or four letters that sound good
together
so let's clean this up a little bit you
have a Q-tip
oh my finger I miss my finger
the guy trying to do a gotcha on the
acronyms
Futo is not an acronym Futo does not
stand for [ __ ] you Tech oligopoly
Futo is just four letters that sound
good together
that's it
four letters
sound good together
four letters
I gotta get a garbage pail at some point
okay so do your best adding flux to get
rid uh and using the wick to get the
solder out of here
here and here those three holes and
sometimes you may have to like sometimes
what will help you is while you're doing
that have a pin that has no solder on it
from the old broken connector that's
kind of shoved in there a little bit and
then pull it out the solder will wind up
sticking to the to this
okay perfect okay here we go so let's
move on to this let me just change the
camera
three four
so so there's two ways that you can
usually solder the smaller two-legged
surface mount components on here and
each of them are equally valid behind
door number one what you can do is you
can solder let's say for a capacitor you
could solder the right pad
tweezers are not supposed to be furry
you can solder the right pad
only slide you know then heat it with
the iron and then slide the component in
and then heat the and then solder the
left pad
because the iron doesn't this is not a
this doesn't have hot tweezers it's just
one piece the second thing you can do is
put solder on both pads and then use hot
air to put the component on either one
of them is fine it's just if you use the
hot air then that means every single
time that you put this component let's
say when you're putting this component
on you're now also heating this one in
that one and that one every single
component goes through another heat
cycle unnecessarily so you want to
ideally you want to keep it from going
through as many heat Cycles so what I'm
going to do one if you can give me let's
say C7 I'll do this and then I want to
see you do the rest
you just have to grab it out of the bag
oh yeah
good to meet you
sure
they
serve
them out entirely sure
this is
once you know which one it is let me
know and I'll put it on as an example to
show you what I mean
before
what is he doing there trying to get the
solder out of the holes he already
pulled out the old janky connector we're
replacing with a new one we're gonna
have to run a couple of jumpers for the
pads that are messed up and then
put a new connector
yeah yeah it's solder braid
one of the things that you could also do
is you could take the braid you could
cut it up a little bit into like a wire
and then shove it through there as
you're heating it
and you could use those green Cutters
for that
they also make solder suckers for
through-hole stuff but I don't have one
anymore because I haven't done anything
through a whole soldering since like
2000
eight yeah 2008.
I like uh tried to clean out the port it
says there's water in it yeah sure in
two years it hasn't been watered near it
uh and then I cleaned out the port uh
and then air and then I was finally able
to plug it in again after like two years
I'm like wow and then now when I do it
it's back to like green beer beef so I'm
just like yeah see what happens to place
the whole thing yeah
what's the that's a Game Boy Color
wasn't working so I was like oh yeah but
this isn't as important okay let me get
this ready because
all right it's just tightened
yeah
okay
that's where you are
kind of sound
why are you not turning on
you're not plugged in
a way oh no this wasn't turned on there
we go
note to self get longer wire
the USBC yeah that is so janky
that would be awesome let's see is it
USBC to USBC it's USBC it's a usba
okay
so you're going to look at it at an
angle like this to see if there's
anything inside of it
and yeah you see little green stuff
that's corrosion okay on the third it's
on the third and the fourth pin from the
left
actually can you hit F3 on my keyboard
by any chance
on the keyboard that's on my desk
yes
I need streaming voice commands
do you see this on the screen now
beautiful all right so let's go over a
little lesson on what corrosion looks
like so
where was I did I have the phone the
other way I think I have the other way
okay so the first two pins on the
from the from the right side the first
two pins are okay the third and the
fourth one has little green gravel the
fifth one is okay the sixth is okay the
seventh eighth and Ninth and tenth pins
from the right have gravel that little
green gravel on it that little green
gravel [ __ ] is corrosion okay so let's
see usually uh like some sort of brush
sometimes a toothbrush and some alcohol
will do it or a air compressor at really
high PSI which is supposed to be
arriving on a truck in two weeks but but
you have an air compressor yeah no no
not like compressed air that's not
enough that's like
yeah like a compressed air can is like
20 30 Max I usually like turn my air
compressor up to 130 or something after
brushing and just blow all that stuff
out but what you're gonna have to do is
get it to the point where you where
there's no green stuff okay I don't know
yeah I don't have any brushes here okay
like a toothbrush will do that all right
or you could try picking it out with a
tweezer which I actually don't have
because somebody stole it the other day
so I don't have one for this desk that
sucks
let's see I have an exact edge here you
go I have a spare
one sec
uh something yeah something dropped over
there
there you go
usually like a toothbrush and some
alcohol we'll do it okay and it's going
back and forth I have alcohol on this
desk
for you to try
okay let's see what we have over here
all right
let me uh solder one for him first give
him an example so that he can get
started and then I'll go back to you
okay
first things first anytime I'm soldering
I turn this thing on just because it
less junk for you to inhale
okay so this over here is an example of
C7 and C4
uh not C4 just C7 okay so C7
sometimes for newer MacBooks we I don't
have the schematics and everything yet
and I can't get donor boards if I don't
have that I will look at the cap and
I'll just eeny meeny miny mo or do a
coin flip and go I think if there's
something that's totally corroded in the
struggle I think that's what goes there
that's right yeah I'm sure that's it
that's good good to know that you have
higher standards for accuracy here okay
so
let's get started
turn on desk
foreign desk
where are you plugged into
um
okay you're plugged into here
and the desk is plugged into
what does this desk plug into
oh this
there we go
yes okay plug it
okay the strategy that I will use here
when I don't have a when I don't want to
use hot air and everything when I don't
have hot tweezers is this ideally you
would have hot choices where you have a
soldering iron that has two ends to it
but I don't have that here and 99 of the
people doing this are not going to have
that available to them so we're gonna do
this I'm gonna
first thing I'm going to do since this
board is only one layer I'm going to
lower the temperature of the iron a lot
there's no need to solder at the
temperature I do on a 10 layer MacBook
board for this
I'm going to set it to like 670 instead
of 840. okay so we take a bit of solder
I'm going to solder the right pad
all right
and take the capacitor
and I'm going to slide it in like this
so I'm going to heat the solder and then
do this
okay
now there
and now I want it to be nice and flat on
the board so I'm tapping the top
doing this
it the component should be flat on the
board this way the for
two-legged components is important so
that they don't it's harder to knock
them off and for components like this
okay it doesn't apply to this board but
often they have a heat sink pad so if
the chip is not flat on the board it may
not be touching the ground to the
heatsink pad in the middle and it can
cause it to get hot or something later
okay so then we go around the side of it
like this
so we're going to add a little bit of
flux it'll make it look nice
so what are the flux for it helps outer
flow so if any time that I'm tapping the
iron to the solder without flux there
you're burning away the flux in the
solder and it winds up making the joint
look crappier okay and it it doesn't
flow like it'll just kind of look like
the stale stained boogers and it doesn't
make a good connection whereas when it
flows naturally it fills in all the
voids and makes a very good connection
the downside is that flux winds up
leaving little bits of what looks like
gooey sperm all over the desk and it's
just kind of disgusting
but the upside is you get a good joint
all right so do that
okay
and yeah so now that I have the flux on
the board I can add some solder to both
sides make it look pretty
um
and here and
there you go
so do that for each one of the
two-legged components and then we'll get
this stuff with more than two legs later
you pretend you're Iron Man
oh [ __ ]
what yeah
what okay
how is this so like you know
yeah mine just snaps mine just snaps
right off
okay
yeah
okay nice I just wanted to make sure I
wasn't like doing this
because okay I did it away oh there you
go okay so I should put a little alcohol
inside first yeah see if you could like
very very gently scrape
but gentle scraping
nice additionalist I got
a fire extinguisher and that's about
that
so I got those clear
very good okay now the next thing is we
have to take an inventory of the ones
that need a jumper
okay so the obviously this one kind of
needs it but the one at the top like
this badly needs them okay
because
whichever the connector goes on this end
right yeah so once you do you have the
new one with you yes
foreign
so once this is going to go in this way
right yeah so once we put this on top
this is kind of going to be covered and
you're not really going to have the
space to solder a jumper in so let me
just change this so they can see what I
mean
yeah so like once this
goes in here
see I don't have a place to really put
my jumper anymore it's like over here I
can see this solder pad is all messed up
and everything so we're gonna have to
come up with that may that may make
contact but I wouldn't trust that you
know I wouldn't trust that's actually
work
and again like stuff like this you're
not going to be able to work on this
once you solder to the other end of the
board
permanent it's not coming up yeah so
what I would probably want to do is I
may want to
take a wire actually put it through here
and then have it soldered on the other
side okay and this is actually going to
be a good time to use the conformal
coating and masks that's probably
another thing that we should go over
so this over here is conformal coating
what this does is it puts an electric it
puts a layer on top of here that does
not conduct electricity and it also it
does not move around with heat so let's
say that I scrape this off right over
here and I make a jumper wire that goes
to the other side of the board but then
I'm using heat to solder what that's
going to do is it's going to move around
my jumper wire and it's then going to
and also this over here is all going to
be electrically exposed and I don't want
it to be exposed let's say some little
random piece of metal
you know gets stuck like right over here
and goes on top of the wire that I put
over there like that that would yeah
this this is a way to avoid Bridges so
each time we I put a jumper I'm going to
use some of this UV curing solution and
so this is a liquid you put on and then
you put a battery inside this pen which
I hope to God I have somewhere and uh
then we uh and then we cure it and while
you're using the UV curing stuff this is
a UV goggle so that the UV doesn't hurt
your eyes okay
okay so let's I will what I I will like
do an example on one of them and then
I'll have you do the rest of them
the top
um I think it
the way it gets jumped it comes down to
the bottom pits
yeah
it's going to get soldered to the to the
the bottom pins okay these are the
bottom four pins yep that's even scarier
actually
so the bottom four pins
actually wanna
okay one of those numbers let's see once
you said the bottom four
so that's going to be
now my question is so the this this
doesn't exist that goes to something
that goes to something that goes to
something yep I removed the pin already
okay let's see all of these look like
they're manageable so I'm gonna say you
said the bottom one so which ones are
the ones that are not getting used it's
going to be it's gonna be the the top
four okay the top four don't get used
so is anything down here yeah like this
this is bad that's gonna have to get
what what is this that's a literal Chasm
over here and this like what is this go
to so we're gonna have to figure out
what these three things go to
which were the three let me just make a
note of that again okay so this this one
on the bottom that's destroyed this one
I know it goes to the trace is already
there
and this the chasm ones let me just
what is is there any hint on the other
side of the board as to what that is for
that's this
okay so this is the one that like
concerns me
what is this for
because there's literally there's no
trace on either side here
now if this if this if that's like a
ground pin or not connected then it
doesn't really matter if it is connected
to something
that would suck
let's see is there any hint
yeah because all those holes are kind of
fixable except that one like this
that is there's no real way for me to
read the board and see
so like over here you know that this
Trace goes to this this pad this Trace
goes to this pad but what goes to that
is kind of fuzzy it's obscure yes yeah
that says for
and on this side it is
also fuzzy
now if Chad is Right Chad says that's an
anchor pin which means it's literally
just there to help hold that into the
board
if they're right and to be clear you
should never trust them they're absolute
scum and villainy but if they're correct
that means that we're that we're not
screwed
which one was I like
yeah this like what is going to this
and the other worrisome thing is that so
this
let's see this Trace is going to
this pen over here but it's also if
there was a pad over here it would be
touching that that's kind of it's kind
of curious what is going on over there
is no way to adjust the image on this
thing make it look less like [ __ ]
you go to there you go there
I'm very curious what this is for
I don't think an anchor pin would be in
the very middle of this
well one way to find out I suppose
there's no hint over here so there's
nothing that I would know about
afterwards
I wonder if anybody actually has a
schematic to this or a board view you
think this is old enough that it would
have that oh yeah okay somebody probably
leaked this at some point
okay so let's fix the connections on the
side that we need to so we have the
connectors here you said it's the the
top four aren't going to use okay so the
bottom
so what
okay so I don't actually have to fix
anything then on this on this top side
the top side is fine as is
so I might as well just clean it off
okay
now to remember the way this works we
want this to connector to be as flat on
the board as possible which means
holding it into place now the remember
the with the rule of soldering is such
that
you can't have the you're not supposed
to have the iron touching anything the
solder if you're not applying new solder
because then the flux Burns away and you
get a crappy joint however you're out of
hands you have one hand for the iron one
hand for solder and one hand to push the
connector into the board so it stays
flat so you're out of hands so what I do
is I add a bunch of excess flux
so if you just give me a little bit of
flux over there so what I'll do is I'll
add flux like this
so that I don't now I don't have to
worry about the flux running out on the
board I can actually keep the eye I can
push the iron there to heat the joint
and still get a good joint
I use one hand to hold the connectors to
the board in one hand for my iron
M all right here we go
so let's do that
so and in order for it to be flat stay
flat on the board if you decide to the
rest without having to hold it
I'm going to do the one on the top right
and the one on let's say the lower left
and then you'll do the rest
so I'm going to add a little bit of
solder to my tip
make sure the tip is clean first
this can you put that in front of that
fume extractor
yes enough thank you
okay
so I make sure that it's pushed as hard
as I can
got one joint in the corner there
and then I get let's say one joint down
here
okay
now you're going to go in and do the
rest and we're going to have to run a
jumper for two of them that are kind of
missing the pads let's see what you got
and use the micro pencil not the big
iron for this let's see what you have
here
let's see what the I tried my uh that's
mine I don't know here's the thing it
doesn't matter if it's a little Jagged
because we're going to do at the end of
it we're going to use the hot air
station to have everything move into
place the only reason I'm not using the
hot air station in the beginning is
because I don't want every single
component to go through like 15 hot air
Cycles Carrie says you could do a
grocery delivery with paper goods yeah
you're assuming that I have time to add
something to the cart before somebody
asks me a question or tries to pick up
the hot end of a soldering iron with
their finger
which just almost happened
let's see I have a tissue box in my car
tissue's a toilet paper
let's see
jackpot jackpot
and no jackpot
aha jackpot yes
keep a box of tissues in my car
finally came in handy
about a [ __ ] bing baby
all right
now if you'll excuse me
some business to attend to
that would be best done while muted
yes
okay let's see what you have here all
right so these last two right here I
cannot hear which ones
show me
the bottom of the bottom left that does
never okay the one on the bottom left
doesn't have a pad anymore and the one
on the bottom right also doesn't have a
pad that's going to need a bit of a
yeah let's see
let me see
this up
yeah okay
yeah
[Music]
okay so first thing this one doesn't
have any solder on it
that that one's gonna have to be fixed
later uh this one over here but so for
this one there's no actual there's
nothing for you to uh
sat or two over here
hmm
yeah so you're gonna have to make a
jumper wire so a little bit of scraping
so you're gonna scrape away at this
Trace over here
then you're gonna solder to it
then you're gonna have to take this
jumper wire
and then just solder the jumper wire
from
here
to there
and this over here let me just make that
a little nice
okay
okay so fix this one joint up here
should be
and let's see what you can do with the
jumper over there
you have a knife on your desk
exacto beautiful
I'll probably go blow some air in there
because a lot of it's loose but I can't
necessarily get it out air compressor
you know I mean if you find an air
compressor somewhere you're not here I
wish
but that would be the best
and then if not then I'll buy a new
charging piece and you just install it
over here yeah we'll go for it my
original thing and then what type of
phone is that uh it's a
note 9. yeah the last the last note with
a 3.5 millimeter
huh
I think that that's all that's
salvageable okay or like a toothbrush
and alcohol if you buy a fresh juice
yeah and it's possible a toothbrush and
alcohol would do it would do you well
even a just a regular fat toothbrush
like well I guess like I think about how
small this is but I guess the bristles
can get in there the finer the brush the
better okay
okay the ones that I forget the one that
the with the packaging that makes it
seem like it's all nature and
eco-friendly like take that because I
have one of those it's horrible for my
teeth but it would be fine for this
because it's very thin bristles yes
in the Game Boy I'll just make that
that's not as important
at least I can take it apart
I don't know how you get I've never
tried to replace the charge port on that
phone before I don't know if that's one
of the phones you have to take the very
expensive and easily crackable screen
off to get to it or anything like that
okay
it's all right there okay
okay so to answer the question of what
flux is for us stop right there
okay so I can see so see the see this
little thing that looks like our
Hershey's kiss that's coming up there
the moment you have that you have a
shitty joint so take this put it over
that where are we we're under C5 yes and
watch that shitty joint look nice so
you're just going to tap it very
yeah but now with the edge of the iron
you want to use the like you're not
going to get heat if you do this versus
doing this okay so like that that iron
is a knife tip so you have the pointy
tip and then you have the side of it the
side of it is what you're going to get
the most heat transfer with
and also don't tap decided that you're
tapping the side of the component
without tapping the board if that's why
the solder is never making its way down
to the board so you want to let's say
this is let's say this is the component
and this is the pad you don't want to
tap you're not tapping this because then
this is never going to get hot and the
size I'm going to stick to it the solder
is going to go to whatever's hot so you
want to have the on the knife tip touch
the point between the capacitor the
component and the pad okay if you keep
tapping this this is never going to get
hot and this Auto is going to keep
climbing like it is there so clean all
the excess solder off of your tip with
this
and put put your tweezer and on the
brown part of the capacitor in the
middle and just to pin it down to the
board so that the board neither the
board nor the capacitor move
yes I would put your tweezer and just
tap right there and press down
and now use the iron the way I said
and have it tapping have the iron press
to pad on the board
and also not that long that's the you
like a you know an eighth of a second
Max right each time you do a tap it
should be an eighth of a second you
don't you don't need to keep it there
for three or four seconds and now clean
the excess Auto because you have too
much on there do it again eighth of a
second but now with a clip yeah same one
just like literally eighth maybe a
sixteenth of a second bam okay now you
see how this less excess solder now now
clean the tip and do that about three or
four times very quickly until you don't
have that pile of excess out of there
I'll seem like only touching it for an
eight is sixth of a second or an 18th of
a second you still want to do it a nice
hard press and there you go you see as
you see how the solder is now
encapsulating the component but you
could there's not a mound of it and you
could still see the top of the component
clearly that's a good joint you don't
have that and you don't have that
Hershey's Kiss nonsense going on because
of the flux
thank you Catherine
okay let's see what you have going on
over here
this one yes and then you should be able
to attend that with some solder
and then run a wire
[Music]
okay one sec I'll be right with you
process
FTA
okay let's see what you got
where this
probably move better
let's look through exactly
good good good good
good good good good good good
almost
the same path
better okay and you got your jumper
there
now again the main thing that I'm scared
about is where did that go to up there
where does this go to down here
not much to
you're gonna be here tomorrow correct
yes sir yeah we can do a 2d continue my
son's gonna be getting out of school
soon okay well yeah absolutely I would
love to see if this actually works and
I'm more than happy to help you continue
troubleshooting and working on it thank
you so much for coming by I really
appreciate it
it's a pleasure meeting you in person
everything yeah exactly it looked this
looks much better than my first my chip
job by fire by far
