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
- 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
