Dear Technetters,
We are seeing some titanium residues (confirmed by EDX) on solder joints after wave soldering post wash (that is not to say they are not present post wave, more analysis is ongoing). Water soluble process, high lead alloy, and a saponified wash. So far the Ti residues are only detectable on the solder joints, not on the assy surface. For general information. what are some possible sources of Ti on the assembly?
Regards,
Amol
