Abstract: The value of heat flow hood test is introduced based on the extreme environment of military application electronic products. The cover is fully set on the tested queue and keeps the device at the set limit temperature point for a long time to conduct the general application test, it can more accurately reflect the direct and real characteristics of the product under the extreme environment. In this paper, the accuracy of the operational amplifier is further demonstrated by comparing the operational amplifier with the hot equipment and the current box test method. Test methods provide participants for military electronic products in high and low mix test.

Key words: monolithic integrated circuit, heatshield oven, high and low temperature test
