Werner, I have no problem being included as "others," but it seems, for all us others, we are coming closer together about this issue. I'm basing this on what you are now saying. As far as not stating "evidence," I did provide sources for it so it may be obtained and used more objectively. I never intended to be the source - just the messenger and long time user of the source's/message's content. If you have other objective evidence, state or you will be guilty of the same offense. At least, I want to thank you for continuing a brave struggle and for admitting one very important thing. If it don't solder the first time, why do it a second? Something I am very curious about and, obviously, have little knowledge of, is HASL solder coating thickness. I always was informed the process, because of the leveling characteristics no matter how many times repeated, didn't add more thickness as the process kept it relatively inconsistent. Also, I believe Afri should be more a part of this ongoing discussion. His original question was what? I belive it had to do with multiple passes through HASL and what negative affects might be encountered. I took this to mean not just solder wetting (at HASL) and effective solder joint formation, but initial quality and long term reliability of boards and solder joints. Afri, where are you? There is so much more you have stated not originally addressed either in the original question or your initial rebuttal. It all adds up to the need for a better understanding for/by all us "others." And on it goes?
