METHOD FOR MANUFACTURING PRINTED CIRCUIT BOARD AND PRINTED CIRCUIT BOARD MANUFACTURED BY THE SAME

摘要

A PCB and a manufacturing method thereof are provided to suppress an erroneous wiring due to burrs by removing burrs on an edge portion of the window slit and a circuit pattern. A circuit pattern for forming a control circuit for a PCB(Printed Circuit Board) is formed on first surfaces of at least two bases(S1). A window slit is used to electrically couple the circuit pattern with an element which is mounted on the PCB(S2). A basic member is formed on the PCB(S3). The basic member for the window slit to connect elements on the PCB with the circuit pattern is removed(S4), so that the window slit is formed. The bases are pressurized against each other by using an insulation material, so that the circuit patterns are arranged to face each other. An insulation film is formed on a position for the base, after the base is removed. A via is formed to electrically couple the circuit patterns on both sides of the PCB with each other.
