Take the guesswork out of purchasing a HALT chamber.
An important part of any reliability improvement effort is accelerated stress testing, frequently referred to as Highly Accelerated Life Test (HALT). HALT is a stress test regimen that imparts random vibration and temperature stresses to a device under test (DUT). The stresses applied will precipitate failure of the weakest parts of the DUT so that they can be analyzed and redesigned to improve the reliability of the end product. HALT testing is performed in an environmental chamber (HALT chamber) specifically designed to impart temperature and vibration stresses both separately and together. Choosing the right chamber for a product can be complicated. Six issues often overlooked when comparing specifications of a chamber are: internal chamber size, overall chamber external height, input and output ports, chamber operating noise, when to start the ordering process and manufacturers’ warranties.
