MANUFACTURING METHOD OF PRINTED CIRCUIT BOARD FOR CAMERA MODULE AND CAMERA MODULE FOR PREVENTING FOREIGN SUBSTANCE

摘要

PURPOSE: A printed circuit board for a camera module to prevent a foreign substance and a method for manufacturing the camera module are provided to form a foreign substance blocking coating layer on a fractured surface of a printed circuit board, thereby originally preventing defects due to a foreign substance. CONSTITUTION: A cover film is formed on both sides of a PCB(Printed Circuit Board) for a camera module(150). A punching process is performed to form the external form of the printed circuit board. A coating layer(153) is formed in the side of a punched part(152) of the printed circuit board. If the forming process of the coating layer is completed, a foreign substance is arrested to the coating layer. The separation of the foreign substance is prevented from the side of the punched part. The cover film is removed.
