What happens to a circuit board that moves from a freezing night at minus 75°C to a blazing engine bay at 220°C in just 3 seconds? Many products crack, peel, or stop working. A thermal shock test finds these failures in your lab before your customers find them in the field.
This article explains the temperature range, sizes, specifications, applications, and advantages of the LIB Industry Air To Air Hot Cold Thermal Shock Test Machine, together with customization cases, common questions, and service strength.
The hot zone heats up to 220°C and the cold zone cools down to minus 75°C. A basket carries your samples between the two zones in 3 seconds or less. Thermal shock tests can run from minus 70°C to 200°C.
The hot zone heats up to 220°C and the cold zone cools down to minus 75°C. A basket carries your samples between the two zones in 3 seconds or less. Samples are exposed to test temperatures from minus 65°C to 200°C.

2. Temperature performance
① Pre-heat zone: up to 220°C. It heats from ambient to 200°C within 30 minutes.
② Pre-cool zone: down to minus 75°C. It cools from ambient to minus 70°C within 30 minutes.
③ High temperature exposure range: ambient plus 20°C to 200°C.
④ Low temperature exposure range: minus 65°C to minus 5°C.
⑤ Temperature fluctuation: ≤ ±0.5°C.
⑥ Temperature deviation: ≤ ±2°C.
⑦ Transfer time: ≤ 3 seconds.
⑧ Recovery time: within 5 minutes.
3. Build and control
① Cooling system: mechanical compression refrigeration.
② Interior: SUS304 stainless steel with a mirror finish.
③ Exterior: A3 steel plate with a protective coating.
④ Viewing window: interior lighting, with double layer heat stable silicone rubber sealing.
⑤ Controller: programmable color LCD touchscreen with PID control, plus Ethernet and USB ports.
4. Safety protection
① Over temperature protection.
② Over current protection.
③ Refrigerant high pressure protection.
④ Earth leakage protection.
5. The equipment follows these standards:
① IEC 60068-2-14 Test N for rapid change of temperature.
② MIL-STD-810 Method 503 for temperature shock.
③ JESD22-A106 for thermal shock of electronic parts.
A vertical fan system keeps the temperature even, so every sample gets the same shock. The USB port exports test data and temperature curves for your reports. The Ethernet port lets you watch and run tests from your computer without entering the lab.
A customer in Thailand bought a 2000L Air To Air Hot Cold Thermal Shock Test Machine for electronics testing. They test circuit boards, power modules, and connectors in large
batches. A big load fits in one basket, so one test run covers far more parts than a small unit would.
A typical test profile works like this:
① Hold samples at minus 55°C for 30 minutes.
② Move them to the hot zone in 3 seconds.
③ Hold them at 125°C for 30 minutes.
④ Repeat for 500 cycles to expose weak solder joints and cracked components.
The same method serves automotive parts, aerospace equipment, medical devices, and military grade components.
LIB Industry builds this equipment in two designs. The 2-zone Air To Air Hot Cold Thermal Shock Test Machine design moves samples by basket between a hot zone and a cold zone. The 3-zone design keeps samples still in one test zone while hot and cold air is sent in. Both designs share the same core strengths.
1. Cooling system
① A French TECUMSEH compressor with mechanical compression refrigeration cools the cold zone down to minus 75°C.
② The cold zone cools from ambient to minus 70°C within 30 minutes.
③ The hot and cold zones are kept ready at preset temperatures, so you never wait for a ramp before the next cycle.
2. Other advantages
① Fast transfer: the basket moves samples between zones in under 3 seconds, and temperature recovery takes 5 minutes or less.
② Independent zones: the hot zone and cold zone each have their own temperature control, which gives fast recovery and stable temperature.
③ Strong build: the interior is SUS304 stainless steel with a mirror finish that resists rust and moisture. The exterior is A3 steel plate with a protective coating.
④ Even temperature: a fan driven vertical air circulation system gives every sample the same shock.
⑤ Easy control: a 7 inch touchscreen controller supports PID control, multilingual screens, and multi step programs. The USB port exports test data and temperature curves.
⑥ Energy saving: high density polyurethane insulation reduces heat loss during frequent cycles.
⑦ Heavy load support: the 3-zone design includes SUS304 perforated shelves that hold up to 50 kg per layer. Extra shelves and special shelf sizes are available.
3. Here is how the two designs compare.
