High Pressure Accelerated Aging Climatic Test Chamber For Electronics Parts / PCB
Environmental Stress Screening Test Chamber HAST-4...
What is a high pressure accelerated aging climatic test chamber for electronics parts/PCB?
HAST Chamber – Highly Accelerated Stress Test Chamber. ● HAST Chamber, Accelerated testing is an approach for obtaining more information from a given test time than would normally be possible. It does this by using a test environment that is more severe than that experienced during normal equipment use.
ASLI is glad to be the ODM/OEM manufacturer of HAST chamber,PCT Pressure Aging Test Chamber,HAST test chamber, HAST aging test chamber Accelerated Stress Test Chamber,High-pressure accelerated aging test sales enterprises all over the world!
Hast climate control chamber is widely applied to the testing of sealing property for multi-layer circuit board, IC sealing package, LCD screen, LED, semi-conductor, magnetic materials, NdFeB, rare earths and magnet iron, in which the resistance to pressure and air tightness for above mentioned products can be tested out.

Safety Device
1. Safety device for the pot: If the inner box is not closed , the machine can not start
2. Safety Valve: When the inner box's pressure higher than the machine's undertake value, it will self-relieve.
3. Double overheat protection device: When inner box's temperature is too high, it will alarm, and Automatic cut off the heating power.
4. Cover protection: The inner box's cover is made of aluminum alloy, can protect the worker from scald.



What is the temperature for the hast test?
The test is performed at a specified temperature and relative humidity, or pressure. The atmosphere normally has a temperature of at least 100°C, in a state of water vapor pressurization. HAST is sometimes classified as a combined test when pressure is also considered as an environmental parameter.
