Dave, Sorry to drag this out some more. When I saw this thread I realized that we often get PWB's fabricated with a gold plated edge connector tab. However we have not ever given any specs to the fabricator regarding the gold plating - all we say i

You are correct. IPC wants you to pay for that standard, regardless if you get a hard copy or download it. Generally, it�s pretty boring stuff for production types. [Although, you will recognize some of the goofy things your designers have done to

You might want to check int using a BGA underfill material prior to coating.

we are worried about the coating not being able to cover underneath the BGA. If the coat is excessive then it would cause CTE issues. Also if anybody has data on 85/85, 1000 hrs after conformal coating of BGA, would appreciate if you guys can share

Hi all, We have a PCB without any BGAs on it which goes into harsh environment.We therefore conformal coat it. After assembly the PCBs are expected to withstand "85degc/85%RH for 1000 hours" We now want to add a BGA to the PCB. Does any one have

Why can't you conformally coat the BGA? We do on some of our lines with no adverse affects.

Underfills could improve reliability. If you pick materials right, you could co-cure and underfill and coating.

Who knows something about the reliability of plasti PEMS and its enhancemant by application of conformal coating (Parylene, metal, SiO2, SiNxOx, etc.) ?
