How the Two-Zone Thermal Shock Chamber Works
The CTS Series maintains separate hot and cold environments. During testing, an automatic transfer mechanism moves the specimen basket between the two chambers according to the programmed exposure time and cycle count.
This process creates rapid changes in specimen exposure temperature and helps evaluate potential damage caused by repeated thermal stress.
Typical Applications
The CTS Series supports thermal shock reliability testing for:
-
Automotive Electronics: ECUs, sensors, connectors, and electronic modules.
-
Semiconductors: IC packages and electronic components.
-
PCB Assemblies: Solder joints, circuit boards, and electronic connections.
-
Battery Components: Battery-related materials, connectors, and enclosures, subject to specimen safety requirements.
-
Industrial Materials: Plastics, rubber, seals, adhesives, and composites.
Applicable Test Standards
The CTS Series can be configured for relevant temperature shock procedures, including:
-
IEC 60068-2-14 — Change of Temperature (Test Na)
-
GB/T 2423.22 — Change of Temperature
-
MIL-STD-810H Method 503.7 — Temperature Shock
-
JEDEC JESD22-A106 — Thermal Shock
Test applicability depends on the selected procedure, temperature conditions, specimen load, transfer performance, and chamber configuration.
