HAST Accelerated Stress Test (HAST) is a commonly used testing method in the chip industry to simulate extreme environments and high temperature and humidity working environments that chips may encounter in actual use, in order to test the reliability and lifespan of chips. The principle of HAST testing is to place the chip in a high temperature and humidity environment and conduct accelerated aging testing for a certain period of time to simulate possible problems that may occur after long-term use. Through this testing method, the reliability and lifespan of the chip can be tested in a short period of time, thereby improving the quality and reliability of the product.
The main functions of the HAST aging test chamber include:
Accelerated aging: By providing high temperature, high humidity, and high pressure environments, the aging process of products is accelerated to simulate the long-term aging of products in actual usage environments.
Verify product reliability: Test whether the product can operate normally under high temperature, high humidity, and high air pressure conditions without failure or performance degradation, which helps product designers understand the performance of the product in harsh environments and make improvements and optimizations to the product.
Screening for unqualified products: In the high-pressure accelerated aging test, if the products fail or have decreased performance, they will be considered unqualified products, which helps to eliminate unqualified products in the production process and improve product quality.
Reduce product development cycle: As the HAST test chamber can accelerate the product aging process, the verification of product reliability and lifespan can be completed faster, which helps to shorten the product development cycle and reduce product development costs.
Characteristics of HAST aging test chamber:
Standard design is safer: the inner liner adopts a circular arc design to prevent condensation and dripping, which complies with national safety container regulations;
Multiple protection functions: multiple human-machine protections for various types of overpressure, overheating, dry burning, leakage, and misoperation;
Higher stability: Equipped with self-developed PID control algorithm, ensuring the accuracy of temperature, humidity, and pressure values.
Free selection of humidity: saturation and unsaturation can be freely set;
High intelligence: supports computer connection and utilizes USB data and curve export for saving.
