Patent ID: 8881382

Claim:
A method of manufacturing an embedded printed circuit board, comprising the following operations in the order presented: a first operation of forming a first cavity and a third cavity in a first base substrate, disposing a first device in the first cavity, disposing a third device in the third cavity, and inserting the first device and the third device into the first base substrate, wherein a height of the third device is larger than a thickness of the first base substrate; a second operation of forming a second cavity and a fourth cavity that faces the third cavity in a second base substrate, disposing a second device in the second cavity, and inserting the second device into the second base substrate; a third operation of providing an insulating member having a through hole at a position connecting to the third cavity and the fourth cavity; a fourth operation of disposing the first base substrate and the second base substrate so that one surface of the first base substrate and one surface of the second base substrate face each other, interposing an insulating member between the one surface of the first base substrate and the one surface of the second base substrate, and pressure laminating the first base substrate, the second base substrate and the insulating member together; and a fifth operation of forming a first copper clad laminate on the other surface of the first base substrate, and forming a second copper clad laminate on the other surface of the second base substrate.
