Lead Free Solder

NP make Lead free Solders have compliance with all the requirements of RoHS directives. It has higher mechanical strength, higher yield, higher reliability and excellent wetting. NP Lead-free solder is suitable for use in any wave soldering process. When converting from 63Sn37Pb or other lead-bearing alloy, the solder pot should first be filled with pure tin. The pure tin pot should be pumped in the system for several hours to ensure that all lead from 63Sn37Pb alloy is removed. This pure Sn should then be dumped and the pot can then be changed with lead-free solder alloy.
