Proposed Maximum Limits of Solder Bath Contaminant per IPC J-STD-001E . for Sn/Pb and Lead-Free . Contaminant . Preconditioning Maximum Contaminant Weight % Limit Sn/Pb Alloys. Alloys Dip soldering is accomplished by submerging parts to be joined into a molten solder bath. Thus, all components surfaces are coated with filler metal. Solders have low surface tension and high wetting capability. There are many types of solders, each used for different applications: • Lead–silver is used for strength at higher-than-room temperature. • Tin–lead is used as a general-purpose solder
