Solder Balls @ the Wave Solder Process

Electronics Forum | Tue Nov 27 13:36:22 EST 2001 | jmathis

Solder balls on the topside of our wave solder boards is a real issue. We have found that during the wave solder process, solder will enter through the via holes in the form of solder balls. It seems to be related to flux captured in the vias and o

Thanks Steve- Here is the whole story: The solder balls are appearing all over, similar to a splatter. They are relatively small. We are using H-Technologies S-HQ no-clean solder paste. The stencil is 6 mil and the boards are running in a ABW

Need your help with a referee call on solder balls. See attached pictures. Engineering believes the solder balls and splash in pictures violate IPC-A-610E-2010 section 5.2.7.1. Purchasing on the other hand believes these are acceptable. Info: balls a

From solder material point of view, a solder paste with slow coalescence rate, or slow wetting rate, will be most desirable. Processwise, allowing the paste to stay at soaking zone for longer time will dry out the volatiles, and reduce the chance of

Electronics Forum | Sat Mar 14 09:12:59 EDT 2009 | davef

First, there is no good justification for getting solder on gold fingers. Second, it is well known that solder on gold fingers is unacceptable. So, shipping boards with that condition indicates sloppy quality practices at your CM. Third, that being

We use no clean paste and sometimes experience flux splattering which gives spot on gold fingers. Need help in analize the cause. thx. Dominic, That is STILL a problem huh? It's a tough one to solve sometimes...especially when you have as
