Thermal Shock Chambers / Rapid-Rate Thermal Cycle Chambers

Model TCC-150W, Espec
 

High temperature rate of change with uniformity and reproducibility

The Rapid-Rate Thermal Cycle Chamber is ideal for test requiring quick changes 15°C/min ramp rate in specimen temperature and 23°C/min ramp rate for air temperature. It 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 15°C/min, air temperature ramp rate is 23°C/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 (15°C/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.

Specimen temperature ramp control (Example)

• Test conditions

• Measurement method

45 specimens placed in two rows on two levels in the specimen basket, with thermocouples attached to the surface of each specimen at the control point.
