PRINTED CIRCUIT BOARD AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A printed circuit board and a manufacturing method thereof are provided to increase matching capability in each position of a wiring board in an exposure process. CONSTITUTION: A wiring pattern(1) forms a wiring pattern by etching a metal layer. A print area(2-5) forms a plurality of alignment marks(11-16). Even if deformation or distortion is generated in each print area of a wiring plate, a matching error is measured in each print area(2-5). The alignment mark is simultaneously formed when the wiring pattern is formed in the print area.
