Seam sealing is the process that permanently bonds the package and lid of a device, providing a barrier for the internal components for the device’s operational lifetime. This is typically the last critical step in the package manufacturing process, so it is among the most important.

Seam sealing means bonding a lid to a package base to create a barrier to contamination ingress. Resistance welding provides a solution for many seam sealing applications. So choice the right electrode is very important for the final product’s yield.

We made few kinds of material of electrode to welding the Kovar, invar, stainless steel, golden plating lip material.
