Highly accelerated life testing (HALT) techniques are important in uncovering many of the weak links of a new product. These discovery tests rapidly find weaknesses using … See more

A specialized environmental chamber is required for HALT. A suitable chamber also has to be capable of applying pseudo-random … See more

The equipment under test must be monitored so that if the equipment fails under test, the failure is detected. Monitoring is typically … See more

Environmental stresses are applied in a HALT procedure, eventually reaching a level significantly beyond that expected during use. The stresses used in HALT are typically hot and cold temperatures, temperature cycles, random vibration, power margining, … See more

Test fixtures must transmit vibration to the item under test. They must also be open in design or use air circulation to produce rapid temperature change to internal components. Test … See more

HALT is conducted before qualification testing. By catching failures early, flaws are found earlier in the acceptance process, eliminating repetitive later-stage reviews. See more
