Touch Screen Environmental Stress Screening Chamber Reliability Testing - China

Environmental Stress Screening ESS Chamber Reliability Testing 1 - Advantages of Temperature Cycling: Many independent studies have been conducted analyzing the effectiveness of various types of ESS processes.

Conclusive data has been compiled by many manufacturers of electronic assemblies supporting today's thinking that temperature cycling is the most effective type of screening process.

While it has been demonstrated that both temperature cycling and random vibration together is the most effective screen in terms of identifying latent defects, if a single screen is to be used, temperature cycling is considered to be the single most effective screen in identifying latent defects.

According to the ESSEH guidelines, temperature cycling regularly detected an average of two-thirds more latent product defects than with random vibration alone, which is ranked second most effective in identifying defects.

Stress uniformity is without question the most important aspect of the screening process.

Temperature cycling provides the additional advantage of a uniform stress environment when air flow across the product is tightly controlled.

All areas of the product must be subjected to an equal amount of stress throughout the screen profile.

Some other methods of screening do not offer this uniformity across the product 2 - Standards Implemented and Met GB10592-89 Technical requirements for high and low temperature test chamber GB2423.1-1989 Low temperature test GB2423.2-1989 High temperature test mode 3 - Specifications - - - - # Product Name Model | Environmental Stress Screening Chamber SM-KS-270-70-15 | # Limited sample | This equipment forbid to test and storage following specimens: Flammable, explosive, volatile items Corrosive items Highly toxic items And items may produce toxic substances in the process of test or storage.
