Hermetic sealing of crystal device and MEMS
Joining method：Parallel seam welding
Features of Parallel seam welding
- In parallel seam welding, because the welded area per each welding is very small, low pressure and small welding current will be sufficient, which is suitable for ceramic package.
- In parallel seam welding, welding is made only to the plated layer. Therefore, the base material (kovar) will not be exposed to ambient air, resulting in stable operation over a long period of time.
- Vacuum sealing, where seam welding is conducted in vacuum, is also possible.
- Full automatic seam welder

Micro-joining application: Parallel seam welding of crystal device and MEMS.
A lid (metal) is placed on a ceramic package, and hermetic sealing is achieved by parallel seam welding .
