Hello Doug, thank you for the additional commentary, it has reminded me of another reflow recommendation that I'd like to make in general for readers. It's not specific to O2/N2 in ovens but in the method for creating and managing profiles for numero

You're entirely correct. The gold is most likely gone away. [Don't forget you can check if the surface is still solderable with a hand soldering iron.] We're not sure it it will give you the results you seek, but consider using a dye penetrant fai

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

OK Terrapin, Here it is, roughly half hour after I vented on your reply. I still don't like your attitude to "school" me on this subject. I've been doing this way too long. But I decided that I would satisfy your attempt at "learnin" me. First, I
