PRINTED CIRCUIT BOARD AND LIGHT EMITTING DIODE MODULE USING THE SAME

摘要

PURPOSE: A printed circuit board and an LED(Light Emitting Diode) module using the same are provided to prevent an accident due to breakdown of an insulation layer by improving a withstand voltage characteristic. CONSTITUTION: A first metal pad(110) is formed on a first side of a nonconductive material layer(140). An LED device is mounted on the first metal pad. A second metal pad(120) is formed on the first side of the nonconductive material layer. A second metal pad is electrically connected to the electrode of the LED device. A third metal pad(130) is formed on a second side of the nonconductive material layer. The third metal pad is insulated from the first metal pad and the second metal pad. A via(150) connects the first metal pad and the third metal pad by passing through the nonconductive material layer.
