Feature of can seal welding

In can sealing, metal cap and header are sandwiched by upper and lower electrode, and the entire circumference is hermetic sealed in one welding. It requires large force and large welding current. Furthermore, a projection needs to be provided to concentrate the welding current.

Can sealing:LD/LED hermetic sealing

Hermetic sealing of LD/LED/IR detector

A package is hermetic sealed (can sealed) by welding a cap for the entire circumference onto a header where LD, LED or IR detector is die bonded.
