As a tip for your future repairs, those circular pads are SMD test points. They are used to debug the circuit and always carry an important signal. You didn’t need to restore a corroded test point for the FOB to operate. Nice work
I already saw it in 3:25 at last the doubt came true. but your work always motivates me and find new ideas .... Great job sir.. Have a wonderful day 😊😊
I got in to watching because guitar amps (which I repair) are using smd's. After seeing the price of parts .... I may open a repair shop for phones and tablets.
Great fix as always, btw my purchase of those tweezers and angled 9m nozzle for the Quick came in almost next day. Super pleased with both, tweezers are fantastic no pressure / issues with small caps / res's when assembling boards. To any makers if you have not gotten your tweezers yet ( Mechanic) I highly recommend you do right away as these made working with msop 10 and qfn parts super easy to work with.
This man is determend. Goes through alot of hoops and get the device working👍🏼. I wish i could have someone like you locally. I have 2 graphics cards which have issues and the people here dont have time to try to fix them
As you said in earlier videos that you achieved your hand stability by resting it in the table. I couldn't do that. Idk why. Can you tell more about how?. And also, i am inspired by your work. Great work. ❤️ from India.
Yeah imagine trying to find that fix on a large complex PCB ... I can really understand why some jobs have to be deemed no fix because finding the fix is like finding a needle in a haystack ... could take 1 year.
4:34: That is a round surface mount test point. That doesn't do anything other than allow you to access a probe point for a net on the other side of that via.
You can use them to jump over other traces, or quite often they are used to enable and disable various options or features, or even as configuration settings. In the latter two cases they may be referred to as "straps".
I bought a batch of merc new keys and the first two i used they started the car and they put put a 433mhz signal!!(Eu model) hiwever the fobs didn't open/lock the doors. The led,s didn't light up on the remotes!Is this repairable?
@@lexander9686 yeah i know, the whole sentence is grammatical incorrect, but i hope the message came accros. Typing this now at work in a hurry and on a Phone so....
Just and idea, you could have inserted your thin jumper wire through the hole and it would have come out the other side of the board to know where the trace was going.
At 3:27 in the video you can see a break in the trace line above the pad you before you started to scrape at the pad, isn't that the same issue you fixed with the wire?
What I keep wondering is how a trace just bust out in the middle. That Mother board is in a plastic case. There were no moving parts associated with the trace, from what I can tell, so why did the trace go bad in the middle like that? Thoughts?
In the beginning, I thought the customer sent in the wrong fob. You can change the battery 3 times on the wife's car fob and it still doesn't work on the husband's car. "Oh!", Sorry!
Tbh the default was directly visible on this one, because the mask wasn't in the same color, and this generally show a problem, also if you put a bright light below the PCB (for this type of PCB you see clearly the trace) also the rules is not solder a wire if not needed because this fragilise the pad, and it was totally possible to the multimeter without soldering a wire ^^.

I was screaming at you through the monitor about that trace! I can't believe you didn't hear me! LOL Great job.
yeah hhh lol
if he see it , he will not need the donor board
same here. But this prove that distraction can be a good thing sometimes, is somebody didn't call him maybe he would still chase that testpoint :)
Me too 😀

You don't need luck because you are professional with what you do. Greetings from Lebanon.
I like fob repairs the most 😁... for unknown reason 🤔
less time consuming and mostly simple /obvious faults.
@@lexander9686 I like complicated stuff and such 😁😁
This man is determend.

Ship them out
no joke, your job seems to be very rewarding at times.
I need a job like this... maybe I should step up my electronics repair game
That pad was probably a test-point. Nice repair and thought process to achieve a successful result.
Great idea and this chanel is better than a university
I see you enjoy every time when you make something. Magnificent. Greetings from Belgium
The smile that comes on your face after fix , is priceless 😎
Those golden spots are actually test points used to measure voltages or signals.
Good work! A hug from Portugal
You repair like peanut butter,very fine. Love from india 🇮🇳
The missing pad was a factory "test point". Fred
Thanks Fred.
Lexander
@@lexander9686 My pleasure. Thank you for the great work and videos!
You might try a thermal wire stripper. Maybe even add them to your product list. Great devices.
You can shine a light through the board the see the traces on the other side. Try it!
Excellent teaching ... keeping it simple
As you said in earlier videos that you achieved your hand stability by resting it in the table.
I couldn't do that. Idk why. Can you tell more about how?.

Try pressing ypur hand on the table, it works for me
try corona
All those circular pads are for ICT ( In Circuit Test) at the factory, so doesn`t matter if they are all broken, the key should function anyway!
Nice work Alex!
An exciting video, very nice fix. Sometimes there is just a „try and error“ on a donorboard to get a solution. Nice video. Good job
ربي يسعدكم ويغنيكم ويعينكم ❤️
Awesome video! What is that device you use to capture IR?
As always, quality video.
I watch all your videos,which software u use for microspe, for usb connection
Nice job
MB Key "Fobs" use BOTH Infrared and RF to transmit signals for the remote locking. It also uses BOTH to interface with the vehicle to start it...
In your website you have also soldering iron same as you use?
Good job! Which soldering station and tip do you use?
What is the name?
Weller WX2
use a high light at back of board to understand the location
How do you manage to find stuff you dismantled? I always manage to loose something while I work with small parts.
Anyways good job as always 👍
Big BOSS handels the assembly /disassembly process.
I use a rare earth magnet to hang on to all them little screws. Then I get to wrestle them Back off. Lol

Speech= 97%
if you change the "1 year" to 'years',
you get increment of 3%
and I will delete my comment later.🙂
weird nah I think it's pretty normal 🙃

11:39 that smug you make when you fixed it.
Great job
It Just a test point man 😃
Thanks
usually the bigger round pads are test pads used by quality control at the factory so they aren't vital to the functionality of the board.
Man you are the best
seems like the visual inspection catches a ton of issues- best method for troubleshooting or leading someone to find the issue
You have many neat tools. Get a soldering iron smaller than a baseball bat and your soldering wouldn't look so crappy.
what is the soldering iron you are using?
Newbie question from a hobbiest. What's the point of 0 ohm smd resistors? I would expect it to be cheaper to just keep the trace going?
You can use them to jump over other traces, or quite often they are used to enable and disable various options or features, or even as configuration settings.

Good video
Better than Blue's Clues! ☺
I have a doubt
Why you used hard drive on the back??
What was causing the disturbance???
You're videos are always engaging...

Thats the experience and knowhow in full effect at display in this video.
you might want to rephrase that

What the name of tool that u use for test the button frequency?
Just and idea, you could have inserted your thin jumper wire through the hole and it would have come out the other side of the board to know where the trace was going.
Not if the via is tented, i.e. filled with solder mask. Looked like they all were to me.
Hi can you upload picture of length of wick used on Last video
Iska whatsapp no milega
you can find it on his website.
My strategy would have had finding what the disfunctional switches had in common high on its list.
At 3:27 in the video you can see a break in the trace line above the pad you before you started to scrape at the pad, isn't that the same issue you fixed with the wire?
You never reply to my comment why I want to know which microscope 🔬 you use please tell me I want to buy
He made a video about this. Find it, or go on his website. He sells it there.
He's a busy man, he won't have time to reply to every question.
What I keep wondering is how a trace just bust out in the middle. That Mother board is in a plastic case. There were no moving parts associated with the trace, from what I can tell, so why did the trace go bad in the middle like that? Thoughts?
Hello how can i get a signal tester like the one you use, i'm referring on that tester that you test the signal from key motherboard?
sir, from where can we buy the IR frequency meter that you used?
watching sir
Yeah I was right .
Where do you get your parts from?
I wish you were in india kolkata.
you should have some light source under the board
And do mistakes happen with explosions. I am most afraid to repair switching power supplies and inverters.
It is a Testpoint
Hi i am from the caribbean St.Marten,my key is not working can i send it to you
i guess he should have place that UV goo that he used in the missing pads videos just to make a coat of protection...
If it's a dark stain then is cola damage, if it's a beige stain then it´s latte coffee and if it's a white stain then it´s cvm.
