High Voltage Products

HV Heritage
  • In the 1960s, high voltage vacuum tubes were being used in radar systems
  • SSDI developed and shipped a solid state rectifier tube replacement which had the same envelope as the vacuum tube, but was able to function indefinitely
  • SSDI's 1st High Voltage Product - Solid State Tube Replacement
    SSDI's 1st HV Product (c. 1967)
Advantages of SSDI's HV Products
  • Utilize hermetic components
  • Utilize proprietary processes - developed and optimized over 50 years to set the standard for performance and reliability
    • Spot Welding: 20 - 60 mil leads
    • Soldering: solder applied to all welded interconnects for extra reliability
    • End Tab Attach: utilizing high temperature solder
    • Vacuum Soldering (DAP): eliminates voids in large area attach
    • Vapor Phase Soldering: efficiently solder complex shapes without overheating
    • Vacuum Encapsulation: ensure void free potting and no corona
    • Lead Finish: primarily lead based solder, but can do lead free upon request
  • Wide range of standard and custom high voltage bridges and assemblies
  • Expertise in series, parallel, and series-parallel constructions
  • Design review and analysis to assure that module performance meets or exceeds SCD specifications
