Variety of Surface Areas

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
