Product Description

Rapid Rate Highly Temperature Humdity Climate Test Chamber


What is the HAST chamber ?

In effort to improve the reliability of products, many different industries, just to mention a few, including

semiconductor, pharmaceutical, and solar companies turn to HAST testing as a shorter alternative to THB testing.

The acronym "HAST" stands for "Highly accelerated temperature/humidity stress test" the acronym "THB" 

stands for "Temperature humidity bias". THB testing takes 1000 hours to complete, whereas HAST

testing results are available within 96-100hours. In some cases, results are available in even less than

96 hours. Due to the time saving advantage. The popularity of HAST has continuously increased in recent

years. Many companies have completely replaced THB test chamber with HAST chambers.

Highly accelerated stress test (HAST) was formulated to decrease the test time needed to get useful

results. Due to time constraints on projects, engineers look for a faster solution to learn if their product

meets the standards of their particular industry. HAST testing uses a high temperature(105ºC), high

relative humidity(about 85%), and high atmospheric pressure conditions (up to 4 atm). HAST testing

loads the speciment with heat and moisture stresses to find the concealed defects that could cause

failure for the user relying on it. In testing products for reliability. Defining the test conditions is the primary

step. A comom standard used for HAST is JEDEC JESD22-A110. Test conditions must meet application

conditions in order to make testing relevant HAST testing has also in turn become a more cost eddective alternative.

Fast change rate temperature chamber (ESS chamber)


Application

Products in the design strength limit, uses temperature acceleration techniques (within the lower extreme

temperature cycle, the product produce altemating expansion and contraction) stress changing external

envionment, make the product of thermal stress and strain, through accelerated stress to underlie the

drawbacks of products emerge (prorential parts material defects, process defect, process defects). In order

to avoid the product inuse process, by the test of enviornmental stress and some times lead to failure, cause

unnecessary loss, to improve the product yield and reduce delivery number has a signficant effect of repair,

additional stress screen itself is a kind od process stages of the process, rather than as reliability test, so

the stress screening is 100%, the procedures of the product.
