    Abstract: Disclosed is a method of manufacturing a stacked multilayer structure, including the steps of forming a first circuit layer with bumps on a substrate, punching an aluminum plate to form recesses corresponding to the bumps, forming openings in a plastic film including a glass fiber layer corresponding to the bumps, pressing the aluminum plate, the plastic film and the substrate, removing the aluminum plate, polishing to level the resulting surface, forming a second circuit layer connected to the first circuit layer, and finally removing the substrate to form the stacked multilayer structure. Because the glass fiber layer in the plastic film is not exposed after polishing, the thickness of the dielectric layer is uniform and the reliability of the circuit layer is improved so as to increase the yield.

    Abstract: A method of manufacturing a laminate circuit board which includes the sequential steps of metalizing the substrate to form the base layer, forming the first circuit metal layer, forming at least one insulation layer and at least one second circuit metal layer interleaved, removing the substrate, forming the support frame and forming the solder resist is disclosed. The laminate circuit board has a thickness less than 150 μm. The support frame which does not overlap the first circuit metal layer is formed on the edge of the base layer by the pattern transfer process after the substrate is removed. The base layer formed of at least one metal layer is not completely removed. The support frame provides enhanced physical support for the entire laminate circuit board without influence on the electrical connection of the circuit in the second circuit metal layer, thereby solving the warping problem.

    Abstract: A buildup board structure incorporating magnetic induction coils and flexible boards is disclosed. The buildup board structure includes at least one first buildup unit or at least one second buildup unit. The first buildup unit includes at least one first buildup body, the second buildup unit includes at least one second buildup body. Any two adjacent buildup bodies are separated by a covering layer provided with a central hole for electrical insulation. All central holes are aligned. Each buildup body includes a plurality of flexible boards, and each flexible board is embedded with a plurality of magnetic induction coils surrounding the corresponding central hole and connected through connection pads. The first and/or second buildup bodies are easily laminated in any order by any number as desired such that the effect of magnetic induction provided by the magnetic induction coils embedded in the buildup board structure are addable to greatly enhance the overall effect of magnetic induction.

    Abstract: A film-peeling apparatus is adapted to peel a protective film on a surface of a substrate. The surface of the substrate has a bare area which is not covered by the protective film. The film-peeling apparatus includes a punching member, a connector connected to the punching member, and a controller. The controller is configured for driving, through the connector, the punching member to punch at predetermined positions nearby or on a first edge of the protective film adjacent to the bare area.

    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.
