Kevin: We know of no handy approach to developing recipes. * Certainly programs provided by profiler suppliers give you a good first pass, based on your oven and solder paste. * Second pass in developing your recipe comes through trail and error chan

Hi Bill You said, "silicon". We assume by your discussion that you ment to say, "silicone". For background on silicone and soldering, check with Dow Corning [517-496-6000]. They make a OS2 [VOC-free] silicone stripper and should be able to give y
