Relay Insulation Process Research

Xu Xiao-fei，Jiang Wei-xin，Shao Tong-guang

[Abstract]Using the auxiliary tooling insulation method， the problem of welding defect rate of relay over-wave soldering furnace was studied and analyzed. The results show that different substrate tooling and different thickness fixtures of the same substrate have different effects on relay insulation. The better the heat dissipation performance， the better the heat insulation， and the thinner the substrate， the better the heat dissipation performance.
