Joe: Lemme see, you�re talking about controlling your manufacturing process within 4.6 defects per 100 opportunities or a 4,600 dpmo rate, a cumulative 99.95 acceptance rate, or a �2 sigma process, right? So, it�s fairly basic stuff, eh? First, yo

Rob: Someone's out there turning over stones, eh? Roller Tinning, Rolled Solder. In printed circuit fabrication, a surface coating of tin-lead, typically 1-2 microns thick, applied to preserve solderability. Still available from some fabricators

Mohammed, The first suggested place to start with your question would probably be with your flux Mfr. Push them! The quantity of dross is effected by several factors: The higher your solder pot temp., the higher your dross level... but don't go too
