Brief Introduction

High acceleration stress testing（HAST）

1 Product Introduction

High acceleration stress testing（HAST）Combining high temperature, high humidity, high voltage, and time to measure the reliability of components, regardless of whether they have electrical bias.HASTTesting accelerates the pressure of more traditional testing in a controlled manner. It is essentially a corrosion failure test. Corrosion type faults accelerate and defects such as packaging seals, materials, and joints are discovered in a relatively short period of time.

Bias high acceleration pressure test（BHAST）Utilizing andHASTTest the same variables (high voltage, high temperature, and time), but add voltage deviation.BHASTThe goal of testing is to accelerate corrosion within the equipment, thereby speeding up the testing cycle.

HASTAccelerated stress testing andTHBThe test is similar because the malfunction is caused by the same mechanism. The resulting faults occur at a proportional rate and correlations can be found between activated engines. electrical equipment/Components are more reliable, therefore, thousands of hours ofTHBTesting cannot detect in a short period of timeHASTWeakness of corrosion fault testing.

Type ofHASTThe testing conditions include110or130°CThe temperature,85%RHThe humidity and96Hour by hour test running time. Once the highly accelerated pressure test is completed, the tested sample will be returned to the customer in a moisture-proof bag with a test time label.HASTTesting usually followsJEDECspecificationJESD22 A110High acceleration temperature and humidity pressure testing（HAST）.
