Product Description
PCB Lab Hast 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.

More information will be showing in quotation with spec sheet, thanks.
∈******************************************************************************
Except PCB Lab Hast Test Chamber, we have a similar model with it, such as
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.
Our technical specification
Machine features
Brand new design with perfect round edges, appearance alegant and solemn, equipped with plat no-
counterforce door handles, easy operation.
Imported multifunctional special temperature controller with excellent expansibility, easy operation & easy to understand, stable and reliable controlling, excellent choice for both low temperature and ultralow temperature testing.
Also if you have any query and want to know more, please contact Vickey Huang for help.
