Abstract:
An electronic circuit includes a conductor path on a circuit board, and at least one SMD component, electronic component and/or electromechanical component mounted on the circuit board and connected to the conductor path. A circuit connection is established via a soldered joint and a spring-loaded or stressed springy contact bridge that provides fuse protection. In the event of excessive power dissipation or high temperature, the soldered joint melts or softens and the contact bridge springs open to interrupt the circuit.
Abstract:
An interconnect device is provided with a body through which a plurality of wells has been defined. At least one component having two terminals is provided in one or more of the wells. The component is sealed in its respective well such that the two terminals are accessible on opposite sides of the body. The body corresponds to a Ball Grid Array (BGA) device and is positioned between a BGA device and a printed circuit board (PCB). The component in the well is then inline with a solder ball on the BGA device and a corresponding pad on the PCB. Providing the component in the well frees up surface area on the PCB and also allows for positioning the component closer to a source of a signal. A component in the well is a discrete component having two terminals that may be solderable or made from a conductive pliable material. The terminals may be spring-mounted on the component.
Abstract:
A printed circuit board according to the present invention is a printed circuit board (4) including a component mounting pin (1) made of a metal wire to connect with a semiconductor chip (10). The semiconductor chip (10) is a surface mounting type semiconductor chip having an electrode pad on its mounting surface for use in a flip-chip mounting system. The component mounting pin (1) is formed by using wire-bonding technology. This printed circuit board (4) is able to decrease malconnections or disconnection caused by a difference between the coefficients of thermal expansion of the semiconductor chip (10) and the printed circuit board (4).
Abstract:
A connector device for maintaining a desired spatial relationship for spatially and securely connecting to a platform, such as a circuit board, in an efficient manner. The connector device generally includes a body portion separated from the secondary device, a plurality of legs extending from the body portion for removably attaching the body portion to the secondary device, wherein the plurality of legs each include a foot member insertable within an opening of the secondary device for grasping the secondary device and at least one contact pin extending from the body portion to contact the secondary device on an opposite surface as the foot member. The contact pin maintains the separation between the body portion and the secondary device and includes a spring for providing a counter force against the secondary device with respect to the foot member.
Abstract:
According to one embodiment, a printed circuit board is provided with a printed wiring board and a circuit component mounted on the printed wiring board. The printed wiring board includes a first surface on which the circuit component is set, a second surface formed on the reverse side of the first surface, and a through hole formed penetrating the printed wiring board from the first surface to the second surface. The circuit component includes a projected portion to be inserted into the through hole. The projected portion is deformable between a first state in which a distal end of the projected portion projects to the outside of the printed wiring board beyond the second surface and a second state in which the distal end of the projected portion is situated in the through hole.
Abstract:
A packaging method for assembling a screw to a printed circuit board (PCB) includes the steps of: providing a screw having a head, a threaded shank, and a ferrule enclosing the threaded shank; mounting a stop ring on the threaded shank to maintain a predetermined height from top of the head to bottom of the ferrule; using a tool to fetch the screw and align the threaded shank with one through hole provided on the PCB; releasing the screw from the tool for a flange of the ferrule to extend into the through hole on the PCB; heating to melt a solder layer atop of the PCB, so that the ferrule is fixedly held to the PCB when the molten solder layer is cooled and hardened again; and removing the stop ring so that the threaded shank is retracted into the ferrule.
Abstract:
A method for forming interconnections within a column grid array is provided. The method involves casting one or more columns with at least a compliant core material that increases flexibility between an electronic component and a printed wiring board by at least a factor of two over metallic-based solder columns, and forming the one or more columns to length for interconnecting between the electronic component and the printed wiring board. The method also involves forming a conductive material for the one or more columns to provide electrical interconnection between the electronic component and the printed wiring board.
Abstract:
A double-tuned circuit includes a primary side tuned circuit having a first air-cored coil and a secondary side tuned circuit having a second air-cored coil. The first air-cored coil and the second air-cored coil are opposed to each other so that one opening end of the first air-cored coil and one opening end of the second air-cored coil are capable of being coupled to each other on a coil mounting surface. The coil mounting surface is provided with a first conductive pattern formed adjacent to the first air-cored coil in a direction perpendicular to an arrangement direction of the first and second air-cored coils, and both ends of first conductive pattern are connected to a ground.
Abstract:
A trace carrier is provided. The trace carrier includes a first insulating tube, a second insulating tube, a trace pair, and a sealed hollow insulating cylinder. The trace pair is passing through the first insulating tube and the second insulating tube, and is coiled up in an inner space of the first insulating tube and the second insulating tube. The sealed hollow insulating cylinder encapsulates the first insulating tube, the second insulating tube, and the trace pair, but the four terminals of the trace pair are exposed to the outside of the sealed hollow insulating cylinder.
