Complete Hermetics uses industry standards to create reliable glass-to-metal feedthroughs and seals according to the following system: The thermal expansion of the glass and the metal are carefully measured and controlled to prevent breakage. Complete Hermetics offers many options for feedthrus types and standard. Complete Hermetics offers not only electrical feedthroughs, the most common type we make, but also RF and microwave feedthroughs. Complete Hermetics glass-to-metal seals are very effective in sealing hermetically during severe temperature changes as well as sudden changes in pressure or humidity. Although moderately effective sealing may be produced with simple epoxy potting, fused glass-to-metal seals are usually specified in high-pressure and high-temperature applications. Glass is an excellent insulator and bonds well to metallic surfaces and is extremely corrosion resistant. Glass seals are also very cost-effective when compared to ceramic seals and may be used in a wider variety of applications. Therefore, Complete Hermetics offers a complete line of glass seal products for a wide variety of uses. The pin and body assemblies of Complete Hermetics glass-to-metal seals and feedthroughs can be plated for better corrosion resistance, wire bonding and soldering capabilities. Plating options include gold, silver, electrolytic and electroless Ni and tin.
