HAST (Highly Accelerated Stress Test) chambers reduce the time it takes to complete humidity testing for semiconductors. By elevating temperatures above 100°C and increasing the pressure, simulation of normal humidity tests can be made while maintaining the same failure mechanisms. Tests can be completed in days, not weeks. Our HAST systems have a modern design that's easier to use:
We now offer an "Air HAST" modification for faster testing of lead-free solder whisker resistance to humidity.
