PRINTED CIRCUIT BOARD HAVING ELECTRO DEVICE AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A printed circuit board embedded with an electronic device and a manufacturing method thereof are provided to improve the degree of freedom in a product by connecting a pair of electronic devices through a conductive via. CONSTITUTION: A cavity is formed on an inner layer substrate(S110). A metal layer is formed on one side of a resin layer. The resin layer is compressed on both sides of the inner layer substrate to bury the cavity(S120). A part of metal layer is removed to expose the cavity(S130). A penetration hole is formed on the buried cavity(S140). A conductive material is filled in the penetration hole(S150). The electronic device is mounted on both sides of the buried cavity to be electrically connected through a conductive material(S160).
