1. What is ESS?

1) Environmental Stress Screening (ESS) is a means of screening electronic assemblies at the most cost-effective point of manufacture to expose defects that can't be detected by visual inspection or electrical testing. These defects are typically related to defective parts or workmanship and are normally found as early field failures.

ESS works by subjecting 100% of a group of products to an environmental stimulus or a set of stimuli for a predetermined time for the purpose of forcing failures to occur before shipment, in fact, at the board level.

Failures are normal and expected when ESS is applied. This makes ESS radically different than more conventional certification testing which requires failurefree operation as proof of reliability.

2) ESS is not a test, it is a process.

Key factors for proper ESS implementation are:

1) The stress environment must not exceed the electrical or mechanical limits of the product.

2) An optimum level of stress must be applied to the product.

3) Expected benefits of a properly applied ESS program are:

1) Reduced field repair expense

2) Fewer defects and waste

3) Elimination of less effective screening procedures

4) Lower unit cost

5) Increased product value

6) Improved customer satisfaction

7) Better return on investment (ROI)

3. 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.

4. Besides this, we also provide other climatic chambers:
