Abstract:
1. A method for manufacturing a circuit board for a light emitting diode package, comprising: perforating at least two through holes in a board body made of a thermally conductive metal; forming insulating oxidation layers in predetermined surface areas of the board body, which are adjacent to upper and lower ends of the through holes, and inner wall surfaces of the through holes, respectively; forming first conductive patterns on the insulating oxidation layers to be electrically insulated from the board body; forming second conductive patterns on the board body between the first conductive patterns to be disposed at a predetermined distance therefrom, so that the second conductive patterns are electrically isolated from the first conductive patterns; and cutting the board body in such a fashion that the first conductive patterns are disposed at opposing edges of the board body and the second conductive patterns are located in a central portion of the board body.
