Has anyone had success in soldering these devices, in particular devices from a company callede Pycomp. They are 8 way 0402 sized terminations. I have experemented with the printing process, placement verification & reflow profile. Unfortuanlty, I am

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

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 -

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

I read a few posts here about resistor in led applications. The thing is, the resistor has clarified as this shows:was always use with a power source delivering a higher forward voltage than the led could tolerate(ex: a 9volt battery hook up to a 3w
