That was one of my favourite repairs if I'm honest, it looked a no fix all the way to me with so many missing pads on the vias. Different level of repair at the micro scale of this card, such a clean and tidy repair when finished to. Great job Alex.

Today I didn’t see that coming as I once denied a repair of that type but I’ve just realized solder paste makes the magic. I had it even then but I didn’t even think about it, great job I’ve advanced again through almost everyday I advance. Thanks n thumbs up

These videos are teaching me so much more about PCB repair than I ever thought I needed to know. Thank you very much for posting these videos, the information alone is super valuable, way more so than any college course can provide. I guess experience trumps all huh?

@TheBackyardChemist Год назад

All of these caps near the PCI-E connector are AC coupling caps for the PCI-E differential pairs (data lines), they go to the main IC of the card. They always come in pairs, 1 pair = 1 lane of PCI-E. On modern cards the data lines operate at GHz speeds, and it is critical that the electrical properties of the two traces in a pair are as closely matched as possible.

@mauzzz2418 Год назад

@christopherjackson2157 Год назад

I wouldn't be so quick to consider those mellanox Asics down for the count. In some competing products that I am more familiar with a signal to noise ratio of many millions to one is no problem. They are far more tolerant of electrical noise than they were even a couple of years ago. As I understand it it is less a question of "how much noise" than one of "how random is the noise"

@incandescentwithrage Год назад

@@mauzzz2418 Given that multiple PCIe extension ribbon cables have been shown to still work for a GPU at Gen4 speeds even when daisy chained together, I'd say there's a fair chance this works just fine.

I have been watching your awesome repair videos for about a month or two, I am really impressed by your hard work, your way of identifying the problem easily, and many of your motivating words. Many thanks for you. I am from Ethiopia and I am thinking about starting a repair business but I need the basic and amazing tools you use for repair like the V2 microscope, hot and soldering stations, thermal camera and so on... One day I will have a business like yours in my own country. Anyhow thanks a lot!!!

Your website should use a PID controller to calculate the *next* orders expedited shipping cost as the target variable based on the current price and the amount of expedited orders in the queue. After some amount of time you’ll hit your steady-state equilibrium price.

Pad length of a 0402 component is 0.6mm. He is able to grind a pad/via with a precision of at least 0.1mm and you can hardly see his hands shake at the end of a 10cm long tool under a microscope where a cotton swab fills the field of view. Incredible steady hands and skill!

So they will pay it. To many expedite to many to do in little time. Good luck brotha. Thanks for the content and keep up the good works.

Hi NF loves watching your videos every day I learn something from you as I have a passion for this electronic world. I have a question. 1: When you say meter in Diode mode it means meter in continuity mode or diode mode if so what diode mode does it cause I know diode mode is used to check diodes. 2: What if we don't have an LCR meter can we still check caps with a multimeter but yeah for the inductor we need an LCR meter cause there is no option in the multimeter for measuring inductance that's what I know.

Was the vias' copper getting wider because their connection was one layer down in the PCB? In every way a super professional repair! Incredible to see the beads of solder paste under your microscope. Whatever your religion, enjoy the holidays ahead!

@kmonyt Год назад

Did you test the card before and after? I know the problems were pretty evident and no doubt needed done, but I have to wonder what the issue was. For instance, was the card detected by the OS? Or just not able to bring up the connection etc? I'm inclined to make sure it fails consistently first, then make then fixes, then do the same test and watch it work. Beyond satisfaction, it's nice to demonstrate in a video for the customer, etc

@CB27 4 месяца назад

A line test would probably need a specific spf connector, a suitable cable and another device at the other end. Personally I ask customers for any additional bits if I don't have them and not too onerous for the customer to bring in/mail in.

Maybe you could remove certain categories of items from the ability to have expedited service. If it is something that they could go out and buy, it doesn't make sense to expedite it. But special purpose parts or data recovery does make sense.

@leeroberts1192 Год назад

It looks like there's enough room that the manufacturer could have located the caps higher up the board, which would hopefully reduce the chance of the caps getting broken off

@mauzzz2418 Год назад

offcourse they won't do that, the more cards get broken the more they can sell new ones.

I've been watching for awhile now and one time you told a story about how you took your parents vcr apart.
