Specialists in Hermetics and Plating


Both hermetic and non-hermetic components are used in high reliability applications and in very harsh environments with exacting thermal and mechanical requirements. Testing to ensure these stringent requirements are met is essential and SGA have invested in the people and infrastructure to meet these requirements. Our fully trained inspectors use:

  • Helium mass spectrometers to verify hemeticity to leak rates to the 10-11 range
  • CMM, Verniers, micrometers and gauges for dimensional measurement
  • Insulation resistance, breakdown, resistance and capacitance equipment for electrical performance testing
  • Stereo and compound microscopes for visual inspection
  • SEM with EDX
  • Tensile tester (up to 5kN computer controlled)
  • Ovens and thermal shock

In addition we have close ties with external UKAS an MIL test houses.
