Cleaning lead-free solder wire Environmental protection

Aia lead-free solder wire is mainly composed of tin copper alloy, melting point temperature is relative to lead 63/37 solder wire

It's 40 degrees higher, it's 227 degrees higher, so it's a lot more demanding to solder than to solder with lead, to solder without lead

Due to the characteristics of the alloy, the wettability, fluidity and weldability of the wire are less than that of lead 63/37, so

In the soldering iron power should also be relative to lead tin wire to increase, in the production line, it is recommended to use the temperature of 350-

Between 400, and combined with the use of lead-free soldering iron and lead-free soldering iron head, some customers due to the lack of lead-free soldering tin

Cognizant, the use of low power soldering iron to weld thick diameter solder, resulting in insufficient welding temperature, can not fully melt

Chemical, customers are advised to increase the soldering iron power.
