Hermetically Sealed Packages for Harsh-Environment Electronics

Purpose of Hermetic Packages

Hermetically sealed packages protect sensitive microelectronics against moisture, contaminants, chemical vapor, radiation, vacuum conditions, and extreme temperature cycles. Without hermetic protection, microchips, sensors, and laser components can suffer from corrosion, outgassing, electrical drift, or catastrophic failure. In aerospace, defense, semiconductor, and medical applications, hermetic packaging ensures long-term performance—even in environments where failure is not an option.

Types of Hermetic Packages Offered

Complete Hermetics manufactures hermetic microwave and hybrid packages for defense, aerospace, energy, and medical applications, delivering rugged microelectronic enclosures engineered for harsh environments where reliability is critical.

Complete Hermetics produces high-reliability hermetic power packages using copper tungsten, copper molybdenum, and copper materials to support high thermal expansion, efficient heat dissipation, and long-term hermetic performance through glass-to-metal or ceramic-to-metal seals.

Complete Hermetics manufactures hermetic packages for photonic, fiber-optic, telecom, and biomedical systems, enabling stable high-speed optical performance and providing fully customized solutions from prototype to production.

Precision Sealing & Manufacturing Process

Hermetic packages are sealed using laser welding, seam sealing, brazing, or glass-to-metal sealing depending on mechanical, thermal, and electrical requirements. Complete Hermetics ensures proper metallization, plating, internal routing, and thermal expansion matching to guarantee structural and environmental reliability. Internal cavities can be customized for chip alignment, lens coupling, fiber-optic feedthroughs, or high-speed signal pathways.
