Environmental Simulation ESS Thermal Shock Climatic Test
Chamber
•What is ESS?
•
ESS is a means of screening products to expose defective parts or
process problems that can't be detected upon visual inspection or
electrical testing. Developed to detect product defects and
production flaws in electronics manufacturing, ESS uses thermal
cycling or vibration to expose failures. Environmental stress
screening chambers can be used as part of the manufacturing process
or they can be used in new product qualification testing..
•
KOMEG thermal shock chambers meet the demands of today's
environmental stress screening with proven performance in
installations around the world. Our direct transfer method between
hot and cold is an economical method to achieve rapid part
temperature change for ESS or thermal shock.

•Thermal shock test chamber is requisite testing equipment in
metal, plastic, rubber, electronics and other industries. It is
used for testing the material structure or composite material’s
tolerance degree when exposed instantly in extremely high
temperature and extremely low temperature environment continuously,
so that whose chemical or physical damage due to thermal expansion
and contraction can be detected in shortest time.
Structure of 3-zone thermal shock chamber:
Such chambers heretofore known include one comprising a test area
for the test sample, a high-temperature air conditioning unit
having gas outlet and intake adapted to communicate with the test
area, an outside air supplying unit having air outlet and inlet
adapted to communicate with the test area, and a low-temperature
air conditioning unit having gas outlet and intake adapted to
communicate with the test area. The thermal shock chamber of this
type is provided with three dampers, i.e., one for opening or
closing the gas outlet and intake of the high-temperature air
conditioning unit, another for the air outlet and inlet of the
outside air supplying unit, and another for the gas outlet and
intake of the low-temperature air conditioning unit.
