Cencorp is another, they make routers, we purchased one of these just to depanelize boards. most boards we depanelize are already pre-routed with tabs holding hte boards together. the machine works great.

We have experienced contamination under flat chip arrays. The lab report is still open but it appears to be dendrite growth. We have been trouble-shooting our process and cleaning equipment. My question is are there any specific design or best p

Thanks Dave, I will be sticking with Manufacturing Engineering. These are good guidelines but what is standard clearance for various packages? This is a dimension we usually seek by eye, whether we will have a problem or not. We use straight DI -

There is no standard as such. It's easy to see why. It's too complicated and has such a small payoff. Standoff is comprised of: * Package height * Solder thickness between the pad and the component lead * Delta of pad thickness and solder mask For p

Naw, accounting is boring. Standoff could be an issue. Coupla things: * Above 30 thou, just about any cleaning process, more sophisticated than a garden hose, will produce acceptable results * Below 10 thou, can be cleaned with best efforts, but not
