The Sigma Systems TP781 Thermal Platform with Controller is a precision temperature-forcing system for component characterization, quality assurance, and environmental stress screening. It maintains controlled thermal environments suitable for low-profile RF devices and high-density power components including IGBTs and MOSFETs. The system combines a compact 11″ × 11″ platform with an advanced TS Series controller, delivering rapid thermal transitions and accurate temperature control in laboratory and production settings.
