Abstract
A function test circuit inside a burn-in apparatus is mounted on a burn-in board and specifies a plurality of checked devices which operate normally. An average voltage calculating circuit calculates average voltage for test voltage applied to a plurality of checked devices specified on a mounting section. A voltage correction circuit receives the average voltage and outputs a control signal to control set voltage output from a device power supply generation circuit. Therefore, this burn-in apparatus can set the test voltage applied to the checked devices readily with high accuracy.
