    Abstract: Disclosed is a copper etching method for manufacturing a circuit board, including steps of electroplating a metal copper support layer, coating a thermal sensitive photo resist layer, coating a photo resist layer, performing a process of pattern transfer, removing part of the photo resist layer to form a photo resist pattern, electroplating a metal copper layer to form a circuit pattern, peeling off the photo resist layer, pressing a stacked body composed of a stacked substrate and a stacked material layer onto the circuit pattern to embed the circuit pattern in the stacked material layer, removing the base layer, performing a copper etching process to removing the metal copper support layer, and removing the thermal sensitive photo resist layer to expose the circuit pattern. In particular, the circuit pattern protrudes from the stacked material layer so as to facilitate the subsequent process of forming solder balls.

    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: Disclosed is a magnetic excitation coil structure including a magnetic coil sheet formed of a thin film and rolled as a cylindrical body with a hollow hole, and an insulation layer covering the outer surface of the cylindrical body formed by the magnetic coil sheet for protection. The magnetic coil sheet includes a flexible substrate, a dielectric layer attached to the flexible substrate, and a plurality of patterned circuit layers embedded in the flexible substrate and in contact with the dielectric layer. Each patterned circuit layer is separate, and the upper surfaces of the patterned circuit layers and the upper surface of the flexible substrate form a co-plane. The magnetic coil structure provides an electrical function of coil, which is enhanced by the patterned circuit layer due to its high aspect ratio of the electrical circuit, thereby greatly increasing the whole magnetic flux and electromagnetic effect.
