  • Miniature Accelerometer For High Temperature Automotive And Aerospace Vibration Measurements, 3221C Series
    The 3221C series are hermetically sealed using laser welds and a ceramic - to - metal sealed connector, as well as base-isolated to avoid annoying ground loop interference.

  • Brazing of sensors for high-temperature steam instrumentation systems
    Procedures are developed for brazing a ceramic - to - metal seal and for laser welding of sensor subassemblies into tube walls, induction brazing thermocouples through a tube wall, and furnace brazing triaxial cables, thermocouples, and a vent tube to a guide tube.

  • Thermal analysis of electron gun for traveling wave tubes
    Pierce type electron gun developed at MTRDC consists of a dispenser cathode and BFE (Beam focusing electrode) along with support structures and ceramic to metal sealed cylindrical vacuum envelope having high voltage insulation. In this structure different materials are used and joined together by brazing and laser welding techniques.
  • Hermetic Aluminum 38999 Connector from PA&E (11/06/2009 13:07:20)
    Laser welding is a non-contact, high-precision welding process that exhibits an extremely small heat-affected zone, ensuring components or electronic packages are exposed to the least-hostile welding environment possible. Besides this new aluminum-shell connector, PA&E custom manufactures circular and rectangular DC connectors in a number of configurations including options with standard stainless steel shells that use both Kryoflex ceramic - to - metal and glass-to-metal sealing processes.
  • New FC/APC Fiber Optic Bulkhead Connector From PA&E
    This new hermetic connector can deliver new levels of reliability because it is designed to be laser welded into lightweight titanium or aluminum housings, thereby eliminating a key point of failure: solder joint fatigue. This new fiber optic connector uses PA&E's patented Kryoflex® polycrystalline ceramic - to - metal sealing technology to achieve a leak rate less than or equal to 1X10-9 cc/sec He at one atmospheric differential pressure.
