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.
