Sigma Systems Temperature Plates

These precisely controllable temperature platforms from Sigma Systems provide an open work surface with rapid heating and cooling or holding at temperature. Also known as “hot/cold plates”, they are ideal for testing or conditioning low profile items with a flat surface such as RF devices and high density power device testing (IGBTs and MOSFETs).

Our flexible designs provide:

  • Cryogenic and compressor-based refrigeration systems as low as -100°C and up to +250°C and temperature transitions up to 100°C/min
  • Surface areas from 7 to 700 square inches (45 to 4515 square cm) and larger on request
  • Hole patterns for your fixtures
  • Enclosures for your DUT
