HAST Highly Accelerated Stress Test Chamber

The HAST test chamber is designed to speed up the testing process and shorten the life test of a product or system in a high environment. With the improvement in semiconductor reliability, most of the previous semiconductor devices can withstand the long-term THB test without failure. Therefore, the test time to determine the quality of the finished product also increases accordingly. To improve test efficiency and reduce time, adopt the latest.

HAST Chamber Features

Large-capacity water tank, long test time, fully automatic water supply. The humidity test chamber is not interrupted.
A sample signal application terminal that matches the number of samples.
The humidity test chamber adopts a 7-inch actual color touch screen with 250 sets of 12,500-segment programs. It has a USB curve data download function RS-485 communication interface.
Adopt a high-efficiency vacuum pump to achieve high purity and saturated steam in the tank.
One-piece silicone door gasket, good gas density, and long service life.
It can custom for special equipment according to the different needs of customers. (such as inner box size and deviation can meet different test needs of customers).
Customized product racks can be customized according to the customer’s product appearance and size.
Corresponding to IEC60068-2-66 conditions, with dry and wet bulb temperature sensors. It can directly measure the temperature and humidity inside the box.
This humidity chamber has the functions of slow pressure reduction, exhaust, and drainage. It avoids the rapid change of pressure-temperature after the end of the test to ensure the correct test results.
The Hast testing machine has over-temperature protection. When the temperature inside the pot is too high, the machine will sound an alarm and automatically cut off the heating power.
Anti-scalding protection: made of unique materials to prevent the operator from getting hot.
The Hast test chamber has over-pressure safety protection. When the pressure in the pot exceeds the most working value, the automatic exhaust pressure relief, extreme over-pressure relief protection, and manual emergency pressure relief protection.
Mishandling safety device: If the pot door is not closed, the machine will not start.
Fault abnormality shut down the whole machine power failure processing and fault prompt.
