how to make lead-free solder?
Welding is difficult to do, and it is cheaper and easier to buy. Lead free solder commercial use may contain tin, copper, antimony, silver, bismuth, indium, zinc and other trace metals. Most of the replacements Sn60/Pb40 for conventional lead-free soldering and Sn63/Pb37 have melting points 50-20 ° C higher. The problem with a point spot welding high melting is a manufacturer of electronic products need to use high-temperature rated components throughout the circuit. In addition, the circuit must be made of a different material to handle high temperatures. Finally, the flow of a solder with a melting point higher electricity may be needed.
