FAQs- Air to Air Thermal Shock Chamber

What is the difference between the two-chamber (basket-transfer) type and the three-chamber (damper-switching) type?

In the two-chamber type, a basket physically moves between chambers, resulting in rapid thermal shock; in the three-chamber type, the sample remains stationary while dampers switch the airflow, making it suitable for precision products or testing under powered conditions.

Can the temperatures in the high- and low-temperature zones be set without limits?

No. Typically, the low-temperature limit ranges from -40°C to -60°C, and the high-temperature limit ranges from 150°C to 200°C; the exact limits depend on the specific equipment model selected.

Can the sample be powered on during thermal shock testing?

It depends on the testing requirements. The equipment supports powered testing, but load capacity and cable access port configurations must be confirmed in advance to evaluate the reliability of electronic products operating under extreme temperature differentials.
