Description of Highly Accelerated Stress Test HAST Chamber：
HAST (Highly Accelerated Stress Test) chamber can perform very extreme accelerated test, which is applied to test high temperature and high humidity resistance of product or material under condition of specified temperature (above 100°C), humidity (65% to 100%) and specified pressure. It is widely used in semiconductors, IC packing, plastic sealed parts and so on.
Introduction of the Highly Accelerated Stress Test HAST Chamber
The Highly Accelerated Stress Test Chamber (HAST chamber ) represents an expedited approach to testing the reliability of electronic components, where temperature and humidity are the key environmental factors.HAST aims to assess a sample’s resistance to humidity.It does so by significantly elevating the water vapor pressure within the test chamber, well above the sample’s internal partial water vapor pressure. This method hastens the penetration of moisture into the test sample, providing a rapid assessment of its humidity resilience.
The RIUKAI RX Series HAST chamber significantly shorten the duration required for humidity testing of semiconductors.By raising the temperature above 100℃ and applying the corresponding pressure.These chambers can simulate standard humidity testing while retaining the same failure mechanisms.As a result, testing that traditionally takes weeks can be accomplished in just a few days.
Testing can be completed in days instead of weeks. Our HAST system features a more user-friendly, modern design.Regarding the RIUKAI RX Series, HAST chamber it includes the following models: RX-HAST-350、RX-HAST-450、RX-HAST-550、RX-HAST-650.
Features of the Highly Accelerated Stress Test HAST Chamber:
- It accelerates the aging process and brings accurate experimental results.
- Multiple safety protection devices.
- The test chamber and steam generator are independent of each other, reducing mutual interference and completely avoiding condensation.
- The inner box is made of high alloy, special corrosion-resistant 316# stainless steel with mirror polishing treatment, which is carefully designed and manufactured.
- The box adopts circular arc design,no solder joint process, in line with industrial safety standards.
- Remote centralized monitoring with RS485/RS-232.
- Wide range of humidity options. Saturated type: 100%, unsaturated type: 65% or other.
- A integrated silic gel door gasket, air tightness is very good, and long operation life.
