Abstract: A composite connector incudes a connector, a carrier circuit board, and a plurality of filtering units. The connector is disposed on at least one surface of the carrier circuit board, and multiple connection pins are disposed on at least one surface of the carrier circuit board. The carrier circuit board is disposed on a main circuit board or a main circuit board connector of the main circuit board. The filtering units are disposed on the carrier circuit board and connected to part or all of the connection pins to filter out noise on the connection pins. The composite connector of the invention can have a filtering function, thereby reducing the manufacturing cost of electronic devices and increasing the routing flexibility of the main circuit board.

Abstract: A method for manufacturing a part-embedded circuit structure includes: forming an inner resist layer with an opening on a base member to expose a portion of the base member; forming an inner wiring layer on the inner resist layer which extends into the opening of the inner resist layer; laminating a dielectric layer on the inner wiring layer; forming an outer wiring layer on the dielectric layer opposite to the inner wiring layer; and removing the base member to expose the inner wiring layer in the opening and the inner resist layer such that a level plane is formed.
