Solder wick on Ag/Pd termination

You say, "we have encountered solder wicking on components ..." We expect to see wicking on solder connections. Maybe we're just using different terminology. Please describe the problem that you're seeing.

Assembleon Pick & Place

It's awful hard to justify a purchase based on no information, and hard for them to get information out there if no one's buying them. If I was really interested I'd contact my closest sales rep (from the Assembleon website) and see if there are any

No-Clean Wave Solder Process Control

physically lift board of after fluxing to visually see what is covered, or using thermal fax paper to get to see coverage works well. PROPER low residue or no residue fluxes leave benign insulating residue behind not corrosive.

BGA cracking

Electronics Forum | Mon Sep 15 20:17:52 EDT 2008 | vladig

Hi Adam, Since you don't see any cracking right after re-flow, then the most probable cause is the board flexture during handling/assembly. I bet you see cracking in the outer row(s) and mainly in the corner balls. Regards, Vlad

Flux not foaming

Electronics Forum | Wed Sep 21 09:22:45 EDT 2011 | patrickbruneel

Russ, Try to shake the 1 gallon jug and see if you can create foam on top of the liquid. If you don’t see any foam at all something is wrong with the flux. Patrick
