Validating HALT Tests

Highly Accelerated Life Test (HALT) testing is completed on circuit boards, subassemblies, as well as the device or product level. System level HALT could be difficult in the event that system is physically large in size. Three problems exist. One, most HALT chambers usually do not accommodate large systems. Two, it can be hard to get sufficient vibrational energy into a sizable system to precipitate a failure. And three, temperature changes in the item within the chamber can be prohibitively long for…
