Product Description

Highly Accelerated Temperature and Humidity Stress Test (HAST) Chamber

Product Overview & Application

 

The highly accelerated temperature and humidity stress test (HAST) is a highly accelerated method of electronic component reliability testing using temperature and humidity as the environmental parameters.

HAST is also known as the pressure cooker test (PCT) or unsaturated pressure cooker test (USPCT).

Its purpose is to evaluate a test sample's humidity resistance by increasing the water vapor pressure in a test chamber to an

extremely high level above the partial water vapor pressure inside the test sample. This process temporally accelerates the infiltration of moisture into the sample.

It is widely used in semiconductors, IC packing, plastic sealed parts and so on.

FAQ

Q:Are your company a trading one or a factory?

A:Factory + trade (integration).More than 30 years focusing on environmental test instruments field.

Q:Which certifications do you have ?
A:We have passed the CE certification,the ISO certification ,China high-tech enterprise certificate,etc.

Q:How to choose the most suitable products?
A:Our professional team will give you the best suggestion, when you need some products to make the test, just be patient to tell us the information about your test sample, the parameters you required. Our team may help you find the best one.

Q:Does your product can be customized with my requirement?
A:Yes, of course. We have independent R&D capability with structure engineer, electrical system engineer and cooling system engineer, which enable us to keep flexibility on customer's requirements, including product size, temperature range, product color, etc.
