Hi;

  Today I find a catalog from a local representative of ERSA company, they
have a wave soldering machine named SO-NO-CLEAN that is fluxless and using
ultrasonics into the solder wave ( 20 KHz ) inside a sealed n2 chamber. So
the ability to make hundreds of solder joints is now available. The strange
thing is their web site don`t mention anything about that ...
