PRINTED CIRCUIT BOARD HAVING METAL CORE

摘要

A printed circuit board having a metal core is provided to improve a heat discharge property of the PCB(Printed Circuit Board) by forming an exposed surface on the PCB by removing a part of an insulation layer. A printed circuit board(10) includes a metal core(11) and an insulation layer. The insulation layer is laminated on at least one surface of the metal core. A portion of the insulation layer is removed from the metal core, so that an edge surface of the metal core is exposed to form an exposed surface(17). The insulation layer includes an upper insulation layer(13), which is laminated on an upper surface of the metal core, and a lower insulation layer(15), which is laminated on a lower surface of the metal core. An electric device is implemented on the upper insulation layer. A portion of the lower insulation layer is removed to form the exposed surface.
