Solder in use frequently required sizes to be processed, sheets, blocks, rods, Ribbon and silk and many other.
1) filamentous – often referred to as the solder wire solder, Center of Rosin, rosin flux cored wire, hand-soldering iron solder is often used. Rosin flux-cored wire diameter is usually 0. 5mm、0. 6mm、0. 8mm、1. Omm、1. 2mm、1. 6mm、2. Omm、2. 3mm、3. Omm and other specifications.
2) sheet solder – often used in silicon and other sheet welding of welding.
3) Ribbon solder – often used in automatic assembly lines, automatic welding machine for punching a made from Ribbon solder welding, in order to improve production efficiency.
4) solder paste--made from mixing together of solder and flux, solder when solder paste is first applied to the printed circuit board, and then welding in automatic SMD technology has been used.
