METHOD FOR MANUFACTURING A REFLECTOR FOR LED CHIP MOUNTED PRINTED CIRCUIT BOARD

摘要

PURPOSE: A method for manufacturing a reflection plate on a light emitting diode mounting circuit board is provided to reduce production costs by using a general PCB material. CONSTITUTION: A copper thin film is coated on both surfaces of an insulating layer (100c). The coated material is used as a reflection layer. A cavity is formed in the preset position of the reflection layer. A copper coating layer (120) is formed on the wall of the cavity. A bonding surface between a printed circuit board and the reflection layer is adhered by a bonding sheet.
