Test chambers for
rapid temperature changes
(ESS)Environmental Stress Screening (ESS) is a process which induces latent flaws in a product before it leaves the factory. Hence, ESS is always applied if the reliability of a product requires enhancing.
The application of temperature shock cycling is the most effective method of creating premature failure in the production phase.
Temperature shock cycling for accelerated inspections are determined by test tailoring, with regard to both temperature extremes and the rapidity at which change occurs.
Highly rapid temperature change rates create mechanical and thermal stress in specimens. Therefore it is possible to more rapidly detect weak points in design, material or in the production of electronic assemblies.
5 K/min, 10 K/min and 15 K/min are the preferred change rates.
For special applications we produce test chambers with temperature change rates up to 30 K/min. | | |
