It seems familiar, but nothing that I've actually experienced. I've read some articles about tin-whiskering in lead-free solder. I think NASA has some pretty good analysis (or, at least they did a couple of years ago). The summary is that without

I'm having shorts appear on my QFN packages between pins, usually only after a week or so of power-on operation. The shorts are 1K and slowly down to hard shorts over time. Typically a defective part will have failures on multiple pins. I tried havi

We are having a process related problem with pullup resistors on a controller card which has a I960 micro-processor. The controller monitors signal inputs and it's own resources then blinks a LED to indicate its working. The problem is that after a p

My old boss bought some stuff to clean the lead off of gold fingers. At least that is what he thought it did. What it really did was remove the gold fingers. And quite well I might add. The short answer to your question is no. And if you replate mak

Hi Roderick, Guess it depends on how you define "minor". If it is just a visual blemish in the mask, there will be no affect o the BGA. If it is through the resist there may be a chance of solder shorting, which will affect it, I doubt it but poss
