Specifications

Function and Features

a. The ESS Test Chamber is mainly used in testing the adaptability of electronics, electrical appliances, food, automobile, rubber and plastic, metal and other products, parts and materials in the high and low temperature alternating hot and humid environment when storage, transport and using
 

b. It is an reliable test equipment for all kinds of electronic, electrical, electronics, plastics raw materials and devices to do testing such as cold, heat, moisture, resistance to dry and the quality control
 

c. The new perfect design, the appearance of high texture level, the system extracts Japan, West Germany, the essence of design and manufacture of advanced technology.
 

d. Balanced temperature humidity control system (BTHC), to PID mode control SSR, so that heated humidification system was equal to heat loss capacity, it could be used long-term stability;
 

e. All-capillary, automatic load capacity adjustment system technology, more expansion valve system more stable and reliable, precise temperature and humidity control, heating and cooling rate of rapid, steady, uniform, saving valuable time for users.

Knowledge of ESS:

Environmental stress screening (ESS) refers to the process of exposing a newly manufactured or repaired product or component (typically electronic) to stresses such as thermal cycling and vibration in order to force latent defects to manifest themselves by permanent or catastrophic failure during the screening process. The surviving population, upon completion of screening, can be assumed to have a higher reliability than a similar unscreened population.

Developed to help electronics manufacturers detect product defects and production flaws, ESS is widely used in military and aerospace applications, less so for commercial products. The tests need not be elaborate, for example, switching an electronic or electrical system on and off a few times may be enough to catch some simple defects that would otherwise be encountered by the end user very soon after the product was first used. Tests typically include the following:

• Temperature variations
• Vibration tests
• Pressure
• Flexibility tests

ESS can be performed as part of the manufacturing process or it can be used in new product qualification testing.

An ESS system usually consists of a test chamber, controller, fixturing, interconnect and wiring, and a functional tester. These systems can be purchased from a variety of companies in the environmental test industry.

The stress screening from this process will help find infant mortality in the product. Finding these failures before the product reaches the customer yields better quality and lower warranty expenses. Associated military terminology includes an operational requirements document (ORD) and on-going reliability testing (ORT).
