Radiant heat circuit board, method of manufacturing the same, heat generating device package having the same, and backlight

摘要

Provided is a radiant heat circuit board for mounting a plurality of heat generating devices. The radiant heat circuit board includes a metal plate comprising an integrated metal projection to which the plurality of heat generating devices are attached, an insulation member exposing the integrated metal projection, the insulation member comprising a plurality of insulation layers disposed on the metal plate, and first and second electrode pads disposed on the insulation member, the first and second electrode pads disposed being electrically separated from each other. The first and second electrode pads receives a voltage from circuit wires disposed on the insulation layers different from each other of the insulation member. Thus, a radiant projection may be disposed between the heat generating devices to improve heat radiation.
