Abstract

PURPOSE:To prevent the application of stress to transistors by the equipment of heat sink by a method wherein after a printed plate is screwed to a sub heat sink, transistors are screwed to the sub heat sink and the sub heat sink is screwed to a main heat sink. CONSTITUTION:A projection 18 is exposed through an opening 16, and a printed plate 13 and a sub heat sink 17 are screwed with screws 20 utilizing the equipping part 16. Then transistors 14 are screwed to a projection 18 of a sub heat sink 17 being exposed through the opening 16 with screws 21. By this way, the printed plate 13 and the sub heat sink 17 containing the transistors 14 are made in one unit.
