Vertically Integrated

Winchester makes a variety of assemblies for your hermetic vacuum applications. From Vacuum flanges to custom headers, our machine shop and vast tooling allows us to design and build the best solution for you. 

Sealed with Ceramax®

All Winchester Interconnect hermetic multi-pin connectors utilize exclusive Ceramax® dielectric compound in conjunction with BeCu contacts to create a best-in-class hermetic seal. Ceramax® is impervious to crack propagation, which is the #1 failure mode of conventional glass seals and lesser ceramics.

Customized for Unique Requirements

Utilizing Winchester’s exclusive ceramic dielectric material, as well as joining dissimilar metals through explosion welding, hermetic vacuum brazing, laser welding, and diffusion bonding, we are able to provide superior sealing while allowing for use within a full range of materials – Titanium, Aluminum, Stainless Steel, and Copper.
