ABSTRACT:
A method and apparatus for cooling thermally massive parts includes directing a chilled gas onto an electrical component travelling on the belt of a continuous furnace. The belt is divided into a series of hot and cold zones to provide thermal stressing to the electrical component to detect early life failure. As the component cools, a constant thermal stress is maintained by either lowering the temperature or increasing the flow rate of the chilled gas.
