Accelerated stress test system
For use on medical electronic products, an accelerated stress test system requires hours to reveal how a product will hold up during years of use. Stresses are placed on products through repetitive-shock vibration and temperature change rates that exceed 70°C per minute. The liquid-nitrogen-cooled chamber features high volume and adjustable air distribution to direct airflow rapidly over the product. Access to the internal chamber is provided through doors on the front and back of the unit. The vibration system uses a thermal isolation system to minimize thermal loading on the chamber. Up to 16 accelerometer and 8 thermocouple monitoring channels allow the user to see which stresses are being applied to the product, and the product test system electronically stimulates and monitors multiple product parameters while under stress.
