I have the ability to offer both SAC and SN100C lead free alloys to my customer base. What might occur if a customer is already using SAC305 in their wave and they want to save money and go to SN100C. They now are mixing, tin,silver,copper with tin,c

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
