HEAT RADIATING APPARATUS OF BOARD

摘要

PURPOSE: A heat radiating apparatus of a board is to efficiently radiate a heat generated from electronic components which are mounted on a board, thereby preventing a degradation of the board. CONSTITUTION: A heat radiating apparatus of a board comprises a prepreg(10) which is formed by a resin impregnated into fiber glass, coated copper foil is attached on both sides to form a board(70), a metal core(100) which is integrally impregnated into the resin-impregnated layer and a metal instrument as a heat sink which is connected with the metal core. The board is comprises of the resin-impregnated layer and a copper clad laminate(30) which is attached on both sides of the resin-impregnated layer and on which a copper foil(20) is attached. The metal core impregnated into the resin-impregnated layer of the copper clad laminate is made of Al. The metal instrument is mounted on the board to be protruded toward an outside of the board.
