PCB Thermal Shock Test Chamber Air Thermal Shock Test Chamber  is equipment used to test the tolerance of materials or products under rapid temperature changes in the air. It is widely applied in various fields such as automotive parts, electronic products, and plastic products to evaluate the performance and reliability of materials or products in extreme temperature environments. Based on structural types, air thermal shock test chambers can be divided into two types: two-chamber and three-chamber. Among them, the three-chamber thermal shock test chamber is more secure and reliable because the three zones (heat storage zone, cold storage zone, and test zone) are completely independent, achieving rapid temperature alternation through damper switching.

Internal volume 80L

Internal chamber dimensions 500*400*400mm   (W* H *D)

External dimensions (approx.) 1600*1800*1700mm   (W* H *D) Please note whether the transportation path, site, length, width, height, etc., are restricted

Weight approx. 750㎏

Test chamber temperature range -40℃～+150 ℃ (air-cooled)

Low-temperature shock range -10℃～-40 ℃  

High-temperature shock range 60℃～150 ℃  

High-temperature chamber

Preheating temperature range RT～+165℃

Heating time +50℃→+165℃ ≤30min

Note: Heating time refers to the performance when the high-temperature chamber operates alone

Low-temperature chamber

Precooling temperature range RT～-55℃

Cooling time +20℃ → -55℃≤ approx. 60min

Note: Cooling time refers to the performance when the low-temperature chamber operates alone

Test chamber (sample area)

Test method Adopts a unique heat storage and cold storage structure, forcing the switching of hot and cold air paths into the test area. During the shock, the temperature from the high-temperature or low-temperature zone rushes into the test area to complete the thermal shock test.

Temperature fluctuation ±0.5℃

Temperature deviation ±2.0℃

Temperature recovery time ≤5min; Temperature transition only requires ≤10s (damper opening time: within 3 seconds)

Shock time ≥30min

PCB Thermal Shock Test Chamber Air Thermal Shock Test Chamber are both important testing equipment, differing in testing principles, application fields, structural types, etc. When selecting, one should choose based on their own needs and actual conditions.
