Thanks for Sharing. It's obvious you share your knowledge willingly, in detail. This specific video got me a serious headache because of those movements! I noticed on other videos your efforts on having the items being under your camera. In this one you could have done better by putting your camera on a tripod.
Hello Richard, Do you feel that you didn't get enough bottom heat into this board or was it more that the top heat was to focused just on the chip? As you mentioned, working on a variety of boards, means that they all react differently.
Any value in running some 'board heating tests' 1st. IE just running the bottom heat for the profile and then probing the top of the board to determine how evenly it heated?
Enjoying the Vids, thanks. I started messing about with this type of stuff during lockdown to learn a bit more. Nice BGA machine btw. Beats my hand crafted set up I'm rigging up!
Check out this video as well th-cam.com/video/XWUPfBW28zY/w-d-xo.html The semi-auto rework station has the advantage of producing repeatable results if you are working on one type of board over and over again (eg games console repair) but if you work on a wide range of boards like I do this can become something of a curse. The machine is basically fire and forget, so you have to try and select a suitable profile for your board. Get it wrong and it will happily destroy things. The more I practice the better I get at guessing the best profile to use, but it is still somewhat hit and miss. I want to make some videos where I work out the cheapest possible off the shelf kit to do reliable BGA rework - if/when the channel has some budget to spend I will start buying kit and experimenting. Watch this space.
@@LearnElectronicsRepairYes I saw. I'll let you know how I get on with mine. For the pre heat I bought a couple of 600w ceramic heaters from China and got them running off a T/C controller and a solid state relay I had lying around. Going to use a cheap 858E hot air station and T/C for the top heat. Just waiting for some square BGA nozzles. Cheap and cheerful but Im hoping it will deal with gpu dies.
@@blagzster6255 Obviously we are both trying to prove the same thing, though probably for different reasons - did you watch this video where I tried this using very basic equipment th-cam.com/video/x9Xiv19Kx-8/w-d-xo.html From my experience so far this is a lot more to do with distributing the heat evenly than it is about getting enough heat into the job. I also tried with the same equipment on another board and removed a LGA socket OK but actually managed to seriously burn the board trying to fit a replacement. I didn't upload that one but if there is enough interest and I still have the video files i will do just that Richard
@@LearnElectronicsRepair You know what Richard, those of us who have worked in any kind of engineering fault finding environment know that you learn more from your mistakes than your successes. Personally I really like it that you post videos when it doesn't quite work out.

You are best electrics eng that I have seen

brilliant video, never seen this done before. unlucky with board. Thanks for your time.
Heya, I can't imagine how difficult that is only a lot of practice can learn this work
thank you, the last video was labelled 8600gs or something like that, i assumed that it was a different job all together thank you!
I'll check that and correct it if I can
