[0002] A high-voltage accelerated aging tester, commonly referred to as a HAST (Highly Accelerated Stress Test) or PCT (Pressure Cooker Test), is an environmental stress testing device used to accelerate the aging process of products. This tester tests products in high-temperature, high-humidity, and high-pressure environments to simulate and accelerate the aging phenomena that products may experience in long-term use or extreme environments. This allows for a relatively short assessment of product reliability and durability, prediction of product lifespan, and identification of potential design flaws.

[0003] High-voltage accelerated aging testers are widely used in industries such as electronics, semiconductors, connectors, circuit boards, magnetic materials, polymer materials, and photovoltaic modules.
