Espec LHL-113 Temperature & Humidity Cabinet
Preconditioning is performed prior to package level reliability testing to simulate the effects of board assembly on non-hermetic devices where moisture may have been absorbed during normal storage. The subsequent exposure to high temperature during infra reflow assembly can cause internal damage such as “pop corning” and delamination.
During preconditioning, devices without any electrical bias applied are subjected to dry baking, temperature and moisture soaking, solder IR reflow simulation, and functional test before being used for package level reliability testing such as HAST, UHAST, THB, Temperature Cycling and High Temperature storage.
Reltech provides a full capability for Preconditioning as part of a full turn-key solution to package level Qualification testing.
