How many solder data lines can be soldered in 8 hours?

400 ~ 600 solder data lines can be welded in 400 ~ 600.8 hours. Solder data consists of tin alloy and additives. The alloy components are divided into tin and lead and lead-free additives, which are evenly poured in the middle part of tin alloy. Different kinds of additives are different for welding wires. The auxiliary part is to improve the auxiliary heat conduction of the welding wire in the welding process, remove oxidation, reduce the surface tension of the welded material, remove the oil stain on the surface of the welded material and increase the welding area.
