I have managed to lift a pad whilst removing FETs from my PCB...does anyone know if PCBs can be repaired by putting a new pad on? Or is the board stuffed? Maybe someone in electronics can provide some advice/opinion....the reason I am hoping that it can be fixed is because my LES sells a "silver conductive varnish" that "repairs printed circuits......adheres well to PCB material" Reading the blurb it insinuates that I can fix a missing pad by making a new one with this stuff. Any comments?
thanks Drac...I will have to look carefully at it and see if I can do it....but i am still going to try the silver conductive varnish first.....I might try to find out more about it first......but I am hoping that I can fix it. this sux...but it's what you get for DIY sometimes..and trying to fix something that ain't broken!! hehehe
pin 3 is for positive source of the fet! I had the same problem before and I actually have 2 of the pads gone and both are gates too! What I did though is got a piece of magnet wire and strip both ends then solder the one on top stack of pin 3, in your case, and the other to the positive/red wire. This should work!
Mr E....positive/red wire......as in the battery wire? If this is the case then thats easy (ish!) Thanks!
Also..what gauge wire did you use? 30 AWG? 28 AWG?
hehehe...very expensive fiddling!!! but we cannot help ourselves....just HAVE to change tings don't we!!!!! Mr E...you are a PCB saver! thank you mate!!
that's what's wrong with mine too (it's actually pin 2 and pin 4) of the inner fets). it'll take more my diagram to show this one but it's still fixable! psyklops, if you can find me a pic of a miniz esc and e-mail it to me that would be very helpful for me to explain it 2 u more!
Myster E you have easily made my day!!! I will do my upmost to find a pic of the PCB. Does it have to be a birds eye view? If so I can take a pic with my camera, but problem is the camera is REALLY bad in quality, so there would not be much detail. I am still in amazement at your depth of knowledge of Mini Z PCBs!!!!!!! Now to start searching for a pic!!!! Unless there is someone with a decent dig camera who feels up to the task of pulling their Z apart for the cause?! We want the side with the big black box, FETs, X-tal slot etc That would be ideal, but I don't expect it!
