When converting to lead-free wave soldering, several important business decisions need to be made. The first decision pertains to the wave solder pot. Wave solder pots designed specifically for lead-free soldering are resistant to tin corrosion, contain higher-grade stainless steal components, and typically contain lightweight titanium hardware such as nuts and bolts designed to float rather than sink if dropped in the solder pot. It is well understood that Sn-Ag-Cu alloys are aggressive toward the materials found in many older wave solder machines. If implementing a Sn-Ag-Cu alloy for wave...
