Abstract:
A PCB module includes a first rigid PCB having a first edge connector, a second rigid PCB having a second edge connector, and a connecting mechanism. The connecting mechanism includes a flexible connecting board, an elastic member, and a fixing member. The flexible connecting has a number of connecting circuit traces isolated from each other. The flexible connecting board is bent in such a manner that a first end portion is in contact with the first edge connector, and a second end portion is in contact with the second edge connector. Thus, the first edge connector is electrically connected with the second edge connector by the traces. The elastic member is compressed between the end portions of the flexible connecting board. The fixing member is configured to fix the first rigid PCB to the second rigid PCB and compress the elastic member.
Abstract:
A method of producing a land grid array (LGA) interposer structure, including an electrically insulating carrier plane, and at least one interposer mounted on a first surface of said carrier plane. The interposer possesses a hemi-toroidal configuration in transverse cross-section and is constituted of a dielectric elastomeric material. A plurality of electrically-conductive elements are arranged about the surface of the at least one hemi-toroidal interposer and extend radically inwardly and downwardly from an uppermost end thereof into electrical contact with at least one component located on an opposite side of the electrically insulating carrier plane.
Abstract:
An array of composite polymer-metal contact members adapted to form solder free electrical connections with a first circuit member. The contact members include a resilient polymeric base layer and an array of metalized traces printed on selected portions of the base layer. Conductive plating is applied to the metalized layer to create an array of conductive paths. The resilient polymeric base layer, the metalized layer, and the conductive plating have an aggregate spring constant sufficient to maintain distal portions of the contact members in a cantilevered configuration and to form a stable electrical connection between the distal portions and the first circuit member solely by compressive engagement.
Abstract:
Disclosed is a flexible printed circuit board with waterproof structure, including a flexible substrate that has a first surface on which a first metal layer is bonded. The first metal layer has an upper surface forming a covered area and at least one mounting zone and the metal layer forms on a surface thereof within the mounting zone a bonding improved waterproof structure. A first insulation layer is formed on the covered area of the upper surface of the first metal layer in such a way not to cover the mounting zone of the first metal so as to expose the mounting zone. A water resistant member is securely mounted to the mounting zone of the first metal layer. The flexible substrate also has a second surface to which a second metal layer and a second insulation layer are mounted. The second metal layer also forms a mounting zone, which is not covered by the second insulation layer so as to expose for mounting the water resistant member. The metal surface inside the mounting zone also forms bonding improved waterproof structure. The waterproof structure improves the bonding strength between the flexible printed circuit board and the water resistant member through proper arrangement and selection of shape, size, and distribution density of holes that are defined in the exposed metal surface. Alternatively, the holes can be made completely through the metal layer in order to also feature control of impedance for high frequency signals.

Provided are a chip component mounting structure and a chip component mounting method, wherein when a plurality of chip components having different heights are mounted on a substrate via an anisotropic conductive film, position gaps which occur when the chip components are pressure-bonded to the substrate are prevented, and the chip components can be accurately mounted to the substrate at target positions; and a liquid crystal display device provided with the substrate. In the chip component mounting structure, a position fixing resin (4) for maintaining the orientation of chip components (2) which are pressure-bonded to a substrate (1) via an anisotropic conductive film (7) is provided. In the chip component mounting method, after the position fixing resin (4) for maintaining the orientation of the chip components (2) which are mounted to the substrate (1) via the anisotropic conductive film (7) is applied to the substrate (1) and cured, the chip components (2) are heated at a predetermined temperature and pressed at a predetermined pressure via an elastic sheet (5) provided on the chip components (2) and, then, pressure-bond to the substrate (1) together. The liquid crystal display is provided with such a substarate.
Abstract:
A printed circuit board reinforcement structure for a printed circuit board receiving a plurality of surface mounting devices, and an integrated circuit package using the same. The structure includes a hard layer having one or more openings formed at areas corresponding to one or more surface mounting devices with a thickness exceeding a predetermined thickness; and a soft layer bonded to a side of the hard layer so that the soft layer can accommodate the protrusion of the surface mounting devices. The structure prevents defects of a printed circuit board, such as deformation, fracture or the like, while substantially reducing the size of a package by applying a reinforcement structure to a thin printed circuit board, thereby reinforcing the rigidity (mechanical strength) of the thin printed circuit board.

An electronic part includes a first electronic member having a wiring side. An anisotropic conductive sheet has a first side and a second side opposite to the first side and is disposed on the first electronic member so that the wiring side contacts the first side. A second electronic member has a third side and a fourth side opposite to the third side and is disposed on the anisotropic conductive sheet so that the second side contacts the third side. The second electronic member is electrically connected to the first electronic member through the anisotropic conductive sheet. An elastic body has a fifth side and a sixth side opposite to the fifth side and is disposed on the second electronic member so that the fourth side contacts the fifth side. A pressing member is disposed on the sixth side of the elastic body.
Abstract:
A mounting method is provided for mounting electric components on both faces of a substrate. Because the electric components on a front face and a rear face of the substrate are simultaneously pressed with first and second pressing rubbers, the electric components can be connected to the front face and the rear face of the substrate at a time. Because the peripheries of the first and second pressing rubbers are surrounded by a dam member when the first and second pressing rubbers deform, the first and second pressing rubbers are dammed by the dam member and not spread. Thus, positional slip of the electric components does not occur. Because the electric components are connected to the substrate at the same positions as at the time of temporary compression bonding, an electric component having high connection reliability is obtained.
