ABSTRACT:
Testing equipment for electric components comprises: a high-temperature section including a homoiothermic chamber in which a plurality of components to be tested are heated, and a first printed board on which the components to be tested are mounted; a low-temperature section including a driving circuit for the components to be tested, a second printed board on which the driving ciruit is mounted, and electric power sources; and a connecting unit for electrical connection between the high-temperature and low-temperature sections. The connecting unit comprises: a third printed board disposed outside the homoiothermic chamber, a first surface of the third printed board facing the wall of the homoiothermic chamber with a space therebetween; a first connector jack mounted on the first surface of the third printed board through electrical conductor pins; and a second connector jack mounted on the second surface of the third printed board. The first and second printed boards are connected to the first and second connector jacks, respectively, and the electric power sources are connected to the third printed board.
