You ned to speak with an apps engineer from a paste supplier that can go through their alloys. I know Indium has such alloys. Any vendor should be able to supply you a list of alloys avbl in NC paste with their liquidous points.

Sorry to contradict your suggestion but the Asahi 300 series alloys contain indium which is both very expensive and has very limited availability.

While Russ is correct that a little voiding is OK, your level of voiding [customer complains that the solder surface looks bumpy] doesn't give us the ol' warm and fuzzy about their process control. For background: * Search the fine SMTnet Archives.
