CIRCUIT BOARD WITH BUILT-IN ELECTRONIC COMPONENT, ELECTRONIC MODULE, ELECTRONIC APPARATUS, AND METHOD FOR MANUFACTURING CIRCUIT BOARD WITH BUILT-IN ELECTRONIC COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a circuit board with built-in electronic component having higher heat resistance property and assuring excellent connection strength of an electronic component and an inner layer board.;SOLUTION: In the circuit board with built-in electronic component where an electronic component 35 is embedded within a printed circuit board, the front surface of connecting terminal, formed on the front surface of the inner layer board on which an electronic component 35 is mounted, is partially roughened and is partially covered with a material 33 selected from silver or tin. Moreover, the surface of a lead-wire led from the connecting terminal is partially roughened and an insulator is formed and an electronic component is embedded therein without via a solder resist to the front surface of the inner layer board.;COPYRIGHT: (C)2008,JPO&INPIT
