The Rapid-Rate Thermal Cycle Chamber is ideal for test requiring quick changes in specimen temperature, and covers various applications from JEDEC, IEC standards to screening. It features new technologies, such as a specimen temperature control function maintaining linear specimen temperature change rates during rapid thermal cycling, and temperature ramp control.

FEATURES
Uniformity, reproducibility Wind simulation allows achieving minimum temperature variations of the specimen, for accurate and quick temperature changes. Specimen temperature ramp rate is 15C/min, air temperature ramp rate is 23C/min.
Greater temperature ramp control High precision of the specimen temperature control achieved thanks to a sensor for temperature specimen measurement, and the embedded high-speed controller. In addition: - refrigeration capacities increased at low temperatures, - minimization of the difference between test area and specimen temperatures, - airflow speed uniformity, lead to excellent temperature ramp control.
Selection of the temperature control mode Two temperature control modes are available: - A specimen temperature control mode meeting ramp rate conditions of JEDEC standard (15C/min.) - An air temperature control mode for temperature cycle tests.
Free access Cable ports are equipped on both left and right side, to ease specimen access and wiring.
