Highly Accelerated Stress Testing (HAST)

A HAST environment is defined by high temperature, high humidity, and high pressure. These three factors categorize the HAST chamber as a destructive environment for standard high reliability testing of integrated circuits. The maintenance of high humidity at temperatures above 100^oC allows for extreme acceleration, up to a factor of 50, of corrosion mechanisms due to moisture.

The CALCE High Altitude Simulation (HAS) chamber, CALCE Mixed Flowing Gas (MFG) chamber, QUALMARK Highly Accelerated Life Test (HALT) chamber, and other temperature/humidity chambers are also available.
