METHOD OF RESTORING PRINTED CIRCUIT BOARDS

摘要

A method of restoring PCBs(Printed Circuit Boards) is provided to have an external appearance to allow final products to have a uniform color through a surface treatment process. A method of restoring PCBs includes the steps of: removing a keyboard of a PCB determined as a defect from a mother board(10) of the PCB and forming a groove at a peripheral portion of a removing region on the mother board; replacing the defected keyboard on the mother board with a normal keyboard and forming a protrusion unit(22) on a peripheral portion of the normal keyboard corresponding to the groove; and allowing a defect metal contact on an overall keyboard to have a uniform external surface by processing the defect metal contact on the overall keyboard of the mother board.
