WEBVTT

00:00:00.160 --> 00:00:07.200
so a short while ago a gentleman by the name of Ls Rossman watched my video

00:00:05.000 --> 00:00:11.960
where I baked a video card and made a video response outlining what an idiot I

00:00:10.200 --> 00:00:15.599
was he said a lot of bad words and a lot of mean things very often the issue that

00:00:14.160 --> 00:00:19.880
somebody's having when they have no video or something is dead is not an

00:00:18.039 --> 00:00:26.039
issue that you're going to fix by taking a heat gun to it by putting it into an

00:00:21.760 --> 00:00:30.240
oven by burning it so I showed up here

00:00:26.039 --> 00:00:34.079
in New York City at his shop to either

00:00:30.240 --> 00:00:36.280
get an apology out of him or for him to

00:00:34.079 --> 00:00:43.440
restate that in fact he is right and show me his super fancy soldering rework

00:00:40.120 --> 00:00:45.760
multiple thousands of dollar setup that

00:00:43.440 --> 00:00:50.440
is actually how you repair graphics cards or other pcbs properly let's find

00:00:48.800 --> 00:00:53.640
out which one of those things it's going to be

00:01:00.199 --> 00:01:06.200
okay so uh employees only means nothing

00:01:03.399 --> 00:01:10.000
to me so I guess we'll just uh go ahead and head

00:01:07.400 --> 00:01:17.560
inside look at all this stuff it's like Linus's Paradise broken

00:01:13.360 --> 00:01:17.560
Max knock knock come

00:01:17.680 --> 00:01:24.079
on so uh here we are the way I see it

00:01:22.360 --> 00:01:28.799
there's uh there's a couple of uh there's a couple of options here you can

00:01:26.479 --> 00:01:32.720
either apologize and say I was right and you were wrong or there's the much more

00:01:30.960 --> 00:01:37.439
likely scenario where you show us the super cool piece of Machinery that you

00:01:34.399 --> 00:01:40.360
use to properly repair all of this stuff

00:01:37.439 --> 00:01:45.040
uh so this is Louis say hi to the lineus tech tips folks I'm sorry for your right

00:01:42.000 --> 00:01:49.200
hand too oh yeah no no that's no problem

00:01:45.040 --> 00:01:52.040
so guys this right here is where the

00:01:49.200 --> 00:01:56.079
magic happens one does not repair pcbs in an oven one uses one of these that is

00:01:54.439 --> 00:02:02.159
to say if one can afford it how much does one of these cost about $7,300

00:01:58.479 --> 00:02:04.240
about 73 $100 and LS here is going to

00:02:02.159 --> 00:02:08.000
walk us through the ins and outs of how this bad boy Works including you said

00:02:06.280 --> 00:02:11.000
you obtained a donor board do I actually get to operate it oh yeah you're the one

00:02:09.560 --> 00:02:17.200
who's going to be putting this on that's the whole point of having you come here was to reduce my workload fantastic

00:02:14.840 --> 00:02:23.160
let's do it okay so I think we all saw this coming um he's not apologizing and

00:02:20.760 --> 00:02:30.040
he is definitely showing me how to do it the real way so this right here is a PCH

00:02:27.160 --> 00:02:33.160
that was sourced from somewhere cuz you can't actually buy this stuff directly

00:02:32.000 --> 00:02:37.800
from the manufacturer that's one of your frustrations right incredible so maybe

00:02:35.760 --> 00:02:44.959
it works maybe it doesn't and then behind me we've got a PCB from a main

00:02:41.159 --> 00:02:48.040
board that was literally thrown and had

00:02:44.959 --> 00:02:50.200
its PCH pop off so without knowing if

00:02:48.040 --> 00:02:57.360
that works and without knowing if this works we are going to resolder this BGA

00:02:53.599 --> 00:02:59.040
chip onto that PCB I'm going to do it

00:02:57.360 --> 00:03:05.599
and it is not going to involve an oven and it is hopefully going to going to work but if it doesn't then that'll be

00:03:02.360 --> 00:03:08.000
pretty fun yeah it'll be fun either way

00:03:05.599 --> 00:03:12.640
okay so Step One is we want to tighten up these little retainers that use the

00:03:09.799 --> 00:03:16.599
mounting screw points and without uh ruining it too hard that use the

00:03:14.239 --> 00:03:26.000
mounting screw points on the PCB to hold it in place as securely as we as we can

00:03:20.720 --> 00:03:28.959
next we pull out this Fancy Pants camera

00:03:26.000 --> 00:03:34.840
so we get a live feed right here of the solder points on the main board next

00:03:32.200 --> 00:03:39.519
step we turn on the manual vacuum right here we take our PCH we Orient it

00:03:37.360 --> 00:03:43.439
correctly which I mean is there some guess work involved there Google image

00:03:41.640 --> 00:03:48.680
search and try to find the GIF that's above 50x 50 pixels like I did 5 minutes

00:03:45.920 --> 00:03:53.640
before you came here perfect so we put this sucker on the little vacuum right

00:03:51.080 --> 00:03:57.920
there hoping that it doesn't come off there we go so we've got a ring of LEDs

00:03:56.159 --> 00:04:01.400
on the top we've got a ring of LEDs on the bottom that makes sure we've got

00:03:59.159 --> 00:04:05.680
great aluminum from all angles both down here and up here and then what we've got

00:04:03.319 --> 00:04:10.959
on this display are two superimposed images so the Brown version is the one

00:04:08.640 --> 00:04:15.840
below and the Blue version is the one above and the idea is that we use our

00:04:13.519 --> 00:04:21.680
horizontal and vertical adjustment knobs here as well as our angle adjustment

00:04:18.639 --> 00:04:24.199
knob right here to try to align all the

00:04:21.680 --> 00:04:28.800
blue dots with all the brown smudges below

00:04:25.600 --> 00:04:31.199
them uhhuh so as soon as I align it

00:04:28.800 --> 00:04:36.120
there it stops Al lining up there feel free to step in and correct

00:04:33.800 --> 00:04:38.880
what I'm doing at any point in time let's see you can give yourself more

00:04:37.600 --> 00:04:44.759
light so you can see a little bit hey there we go you can zoom in and

00:04:40.880 --> 00:04:46.720
out you got a Joys how far in can we go

00:04:44.759 --> 00:04:50.080
I honestly can't tell but you have no way of checking if it's right until you

00:04:48.440 --> 00:04:54.639
just yeah you don't know if it's right until you put it on I'm just looking at one corner at a time so I see that one's

00:04:53.000 --> 00:04:57.840
the line yeah and the other this one looks okay this is a pain in the ass

00:04:56.479 --> 00:05:02.720
this part really is just a pain in the ass so is this pretty aligned that's

00:05:01.160 --> 00:05:07.400
pretty aligned I would say okay just get yourself a thin layer of flux on there

00:05:05.080 --> 00:05:12.840
gloves and a for the next step we will need Z gloves so now we put uh just a

00:05:10.680 --> 00:05:17.360
line of flux just right down the middle yeah so with the flux in place we use

00:05:15.160 --> 00:05:22.440
this clean room wipe as you can see we are in a completely professional clean

00:05:19.759 --> 00:05:27.360
room environment here so now we've got to check and see if our chip moved out

00:05:24.520 --> 00:05:34.520
of alignment from messing around with it this thing messes with your eye after a

00:05:30.400 --> 00:05:36.319
while man let me tell you are we back on

00:05:34.520 --> 00:05:40.960
I think that's actually good okay I would say this is good okay so next we

00:05:38.120 --> 00:05:45.680
move our light out of the way and we actually lower the

00:05:42.520 --> 00:05:48.120
chip whoa that goes really F oh uh it's

00:05:45.680 --> 00:05:51.080
going to stop oh jeez okay see see right now it's touching the board once it's

00:05:49.800 --> 00:05:54.639
touching the board then you turn the manual vacuum off and then you go back

00:05:52.880 --> 00:05:58.360
up okay so now you can move the camera around and try to get it to focus so

00:05:56.440 --> 00:06:03.160
you're you're almost in Focus okay there you go so now we can can see the balls I

00:06:01.240 --> 00:06:06.240
can't I can't make heads or tails of this image though you got to be kidding

00:06:05.280 --> 00:06:11.039
me here okay the point of this is just

00:06:09.240 --> 00:06:14.520
being able to see when the solder melts so this allows us to see under it enough

00:06:12.880 --> 00:06:18.199
to know when we should apply heat and when we should stop applying heat to

00:06:16.639 --> 00:06:23.120
solder the connections okay so Hit Me With Your

00:06:20.919 --> 00:06:28.160
Best Shot you hit start and you hope that nothing blows up seriously pretty

00:06:25.479 --> 00:06:32.199
much so at this stage we're actually ready to use the information heating

00:06:30.039 --> 00:06:37.280
elements all around to heat the general area and then the two heating elements

00:06:34.199 --> 00:06:40.720
on the top and bottom to solder the chip

00:06:37.280 --> 00:06:44.759
to the PCB but it's not as simple as

00:06:40.720 --> 00:06:47.479
just 200° C in a oven which I noticed

00:06:44.759 --> 00:06:52.120
they have an oven this is high quality right here yeah I I noticed you you do

00:06:49.800 --> 00:06:56.319
have computer parts in your oven was that just to make fun of me when I got

00:06:53.400 --> 00:06:59.680
here exactly um what you do is if you want to clean them off after you're done

00:06:58.039 --> 00:07:02.360
Ultras sonicing it you put it in here to get rid of the moisture before you do

00:07:01.039 --> 00:07:06.120
anything like this you also have to put them in an oven at just around the

00:07:04.360 --> 00:07:08.599
boiling temperature of water just to get rid of any of the moisture that built up

00:07:07.400 --> 00:07:12.919
in the chips but also you get things like popcorn and there I thought I was

00:07:10.680 --> 00:07:16.840
getting my apology after all all right so what we do here is we have these

00:07:15.560 --> 00:07:20.120
profiles and it comes with some pre-programmed but they're not very good

00:07:18.560 --> 00:07:24.520
so you kind of have to trial and error it or use your experience or share share

00:07:22.240 --> 00:07:29.160
online to figure out what exactly the temperatures are for the period of time

00:07:27.360 --> 00:07:32.960
and the ramp up and ramp down for each of those those three heating elements

00:07:30.879 --> 00:07:39.000
and then once you've got a profile you press start and hope nothing catches on

00:07:35.400 --> 00:07:39.000
fire and hope that the solder

00:07:41.280 --> 00:07:48.440
melts so once they melt if the profile is set to run a little long we can

00:07:45.479 --> 00:07:51.840
manually stop it and then start a manual cooling cycle in order to cool

00:07:50.319 --> 00:07:59.680
everything back down to a reasonable operating temperature wow it's really hard to tell

00:07:56.240 --> 00:08:01.319
so is it is it is it is it melted stop

00:07:59.680 --> 00:08:07.919
so we're stopping it now we're deciding it's melted even though it's really hard to tell okay manual Cooling and now you

00:08:05.360 --> 00:08:12.440
get to watch the balls dry okay it's important to dry off your

00:08:10.000 --> 00:08:18.159
balls when you're done any kind of uh repair on

00:08:15.199 --> 00:08:25.400
them so now that the cooling cycle is done we lift this bad boy up is that all

00:08:21.680 --> 00:08:28.319
it lifts up oh there it goes then Mr

00:08:25.400 --> 00:08:34.640
shark grabs a PCB and whoop whoop come on and put it uh that was it we're not

00:08:32.399 --> 00:08:37.839
going to let it cool down some more I want to take a look at it first this is

00:08:36.320 --> 00:08:42.800
the part of the class where the teacher is like you know oh this part's kind of

00:08:40.440 --> 00:08:48.680
good but this is but your attendance is excellent the

00:08:45.560 --> 00:08:49.760
suspense you want to look on that one hm

00:08:48.680 --> 00:08:54.399
you want to look and see what it looks like sure yeah let's do it all right so

00:08:52.640 --> 00:09:00.279
let's have a quick look here so what we're trying to see is whether the balls

00:08:57.560 --> 00:09:03.920
got soldered to the pads uh your guess is much better than mine

00:09:02.399 --> 00:09:08.480
at this point in time let's see if it works so we're just going to fire it up

00:09:05.680 --> 00:09:14.200
and YOLO yeah so here we go Moment of Truth we're going to find out if a fan

00:09:10.040 --> 00:09:18.399
turns yeah come on baby I Believe In You

00:09:14.200 --> 00:09:22.040
H oh we got a flash of light

00:09:18.399 --> 00:09:24.000
and we've got 5 volt so it's powered got

00:09:22.040 --> 00:09:31.000
3.3 volt on another test patch yep no good oh now you have this

00:09:27.959 --> 00:09:36.279
my my bad luck rubbed off on me

00:09:31.000 --> 00:09:39.160
we didn't fix it but um test subject 17A

00:09:36.279 --> 00:09:44.000
contributed to the betterment of our scientific knowledge in some way that

00:09:42.079 --> 00:09:50.560
who am I kidding we didn't learn anything today it but uh thank you guys

00:09:47.560 --> 00:09:53.600
very much for tuning into this episode

00:09:50.560 --> 00:09:57.000
of how according to Lewis Rossman one

00:09:53.600 --> 00:10:00.240
would actually fix something that had

00:09:57.000 --> 00:10:02.800
been if it had been damaged

00:10:00.240 --> 00:10:06.320
by you know something like micro fractures in the solder joints or

00:10:05.120 --> 00:10:12.120
whatever the case may be because remember whether it's a GPU like I very

00:10:10.160 --> 00:10:15.000
temporarily resurrected in the oven because that won't last very long

00:10:13.880 --> 00:10:20.120
whether it's a GPU or whether it's something else there's a hundred things

00:10:18.120 --> 00:10:23.519
that could be wrong with it other than that and you actually have to know

00:10:22.320 --> 00:10:28.120
what's wrong with it before you can attempt any kind of repair so while I

00:10:26.160 --> 00:10:31.399
actually stand by the oven method as a way to put off by buying a new video

00:10:29.920 --> 00:10:34.760
card while you save up for another few weeks if you are completely out of

00:10:33.360 --> 00:10:39.279
warranty and you don't happen to have a $7,500 rework

00:10:37.000 --> 00:10:43.880
station it is not the real way to actually fix anything and I'm glad that

00:10:40.959 --> 00:10:47.959
I got to at least try to do it properly so uh thank you very much for going

00:10:46.279 --> 00:10:51.600
through this process with us and uh being a good sport about the whole thing

00:10:49.600 --> 00:10:58.160

his channel he's got a lot of videos that are uh basically tutorials about

00:12:48.160 --> 00:12:55.240
how to repair your stuff uh rants about Apple and the way that they lock out

00:12:53.199 --> 00:12:58.600
small repair shops from being able to repair their products whether it's
