    Abstract: An EMI shielding device is provided. A first shielding layer is formed on a first surface of a first substrate, and a first through hole is formed through the first substrate. A second substrate is mounted in an opening of the first through hole, and a second shielding layer is formed on a surface of the second substrate. A conductive paste is mounted between the first substrate and the at least one second substrate to electrically connected the first shielding layer and the second shielding layer. The EMI shielding device is adopted to be mounted on a printed circuit board (PCB) by Surface Mount Technology. Therefore, the EMI shielding device may be firmly mounted on the PCB, and there is not any narrow gap that may leak electromagnetic radiation.

    Abstract: An antenna carrier plate structure has a first circuit board and a second circuit board. The first circuit board has a first substrate and a conductive connector disposed in the first substrate. The conductive connector has two opposite connecting ends respectively protruding from two opposite surfaces of the first substrate. The second circuit board has a second substrate formed with a through hole, and a connecting plug is disposed in the through hole. One end of the connecting plug is formed with an engaging concave portion for engaging one end of the conductive connector of the first substrate. Therefore, each circuit board can be firmly fixed and electrically connected by engaging to form a multi-layer circuit board module, thereby avoiding joint tolerances during soldering and ensuring a correct connection of the joints.

    Abstract: A method for manufacturing microthrough-hole includes electroplating a metal layer on a carrier plate, patterning the metal layer to form a first circuit having copper pads, covering the first circuit with a photoresist layer and not covering the copper window between two of the copper pads, etching the metal layer beneath the copper window and removing the photoresist layer, sequentially forming an insulation layer and a second circuit on the first circuit and the copper window, the second circuit layer having a stop pad corresponding to the copper window, removing the carrier plate, upward drilling through the insulation layer between the stop pad and the copper window to form a microthrough-hole beneath the stop pad, and forming a conductive layer in the microthrough-hole to form the microthrough-hole connecting the first and second circuits. The microthrough-hole and its occupied area is greatly reduced, thereby achieving high circuit density.
