Hi, I have a customer who's electronic assemblies produce RF. He is insisting upon aqueuos cleaning. We switched to a no clean solder years ago and no longer have an aqueous system. Is aqueous cleaning necessary to eliminate 'cross talk' of

We have come across this where the operator was using thin gauge solder wire (more suited to fine pitch SMT soldering) to form large solder fillets (power connections or sheild cans). We found that the operator was feeding large amounts of solder wir

Thanks Russ! The origianal complaint from the customer was in regards to what appeared as "bumpy" appearance and "holes" in the solder fillet. This problem was originally presented as an appearance issue only. Further investigation by our DPA lab r

Recent cross-section analysis for a customer complaint revealed voiding in the solder fillet. In some cases, the remains of outgassing were also observed. During the failure analysis, we also observed failures where the solder fillet wicked on the

It's definately soldering because the fillet is pulling the solder plating (I believe, from what I can see under available magnification) off of the termination, and some of the nickel plating as well.
