Hermetic sealing of crystal device and MEMS

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.

A lid (metal) is placed on a ceramic package, and hermetic sealing is achieved by parallel seam welding .

We will be pleased to test your sample with our proposed joining method, and return it with a report.
