Plating on Glass for Hermetic Seal 820613

A multicomponent, solderable layer, which can be applied to instrument glass, has been developed. The layer consists of an initial coat of SermeTel followed by an electrodeposited zincate, then electroless nickel and finally tin plated. When tested in tension, the interface was found to be more superior in strength than the base material. While this procedure produces an optimal coating, great care must be used in all aspects of production to insure quality and integrity of the interfacial bond.
