Product Overview

The HAST Chamber (Highly Accelerated Stress Test Chamber), also known as a Pressure Cooker Test (PCT) Chamber, is a specialized environmental testing system designed to evaluate product performance under simulated high-temperature, high-humidity, and pressurized climatic conditions during storage, transportation, and actual use.

This equipment is primarily used for semiconductor chips, electrical and electronic products, components, metal materials, and related products. It exposes test samples to controlled high-temperature steam environments with saturated humidity and elevated pressure to assess physical properties and other performance characteristics. After testing, products undergo inspection to determine whether they meet design and quality requirements. The chamber supports product design optimization, process improvement, verification testing, factory acceptance inspection, seal integrity evaluation, and accelerated life testing of relevant components.

By applying significantly accelerated stress factors, the HAST Chamber enables rapid identification of potential weaknesses, helping manufacturers improve product reliability and shorten development cycles.
