Is this test required

In many industries, safety and quality standards must be met. In automotive, aerospace, electronics, computer, solar cell, industrial, medical, and consumer applications products need to meet standards, such as IEC, IPC, JEDEC, etc. Environmental test chambers are used to test products and ensure meeting those standards.

Various methodologies are used for stress testing: ESS (Environmental Stress Screening), HASS (Highly Accelerated Stress Screening/Testing), and HALT (Highly Accelerated Lifetime Testing).

Thermal cycling (ESS)

is a slow process where the product is brought to the two temperature extremes over a long period of time. Depending on how you want to test your product, you can vary the ramp rates to meet the level of stress you want to put on the product. Thermal cycling is not designed to damage the product, but to simulate environmental conditions encountered over the operational life of the component.

Thermal Shock testing (HASS and HALT) These testing methods are quicker and allows for the product to be taken from extreme and immediately be exposed to other extremes. Those kinds of testing are designed to age, and even destroy the system or components in order to understand and predict failures. Those tests are conducted to discover and improve the product in the design phase and helps to determine factors that could cause weakness in a product‘s design or fabrication. These testing methods have been in use since the 1980s and perform stresses that go beyond the normal stress level a product may experience in its commercial life.

Climatic test chambers expose the products to different temperatures and humidity levels, allowing detecting infantile mortality of electronic components. Not only, environmental chambers can help your meets quality and safety standards, but can also improve product reliability and quality, reduce warranty loss and increase profitability.
