Main purpose:

Zhejiang Large Walk in Constant Temperature and Humidity Laboratory High and Low Temperature Laboratory CabinIt is the use of temperature acceleration techniques (alternating expansion and contraction of the product during cycling within the upper and lower limit extreme temperatures) to change the external environmental stress of the product under the design strength limit, causing thermal stress and strain in the product. By accelerating the stress, potential defects in the product are exposed to avoid environmental stress during use

Failure during testing can result in unnecessary losses, which has a significant impact on improving product delivery yield and reducing repair frequency

The effect.
