We are preparing to run a 2-sided board with BGAs on one side and passives on the other side. We have two schools of thought on which side we should run first. One school says run the passive side first, then run the BGA side and the surface tensio

I need to know the recommended pad layout for a 44r package. The part is an atmel flash AT49F004. Is there a standard that I can look at?
