With twenty five machines working with the LFB227/S on our little island it does seem to work well. Wetting is good compared to Tin/Copper and flow is comparable to 63/37. Biggest problem sticking 3 - 4 % Ag in a solder ignoring the patents and royal

Hi Steve, When I drain our wave solder pot in preparation for loading a lead free alloy (SN100); I am going to use muffin tins dusted with baby powder or maybe a little high temp oil so that the solder doesnt stick to the tins. I know that this may
