Abstract:
Embodiments of the invention include flexible circuit board interconnections and methods regarding the same. In an embodiment, the invention includes a method of connecting a plurality of flexible circuit boards together comprising the steps applying a solder composition between an upper surface of a first flexible circuit board and a lower surface of a second flexible circuit board; holding the upper surface of the first flexible circuit board and the lower surface of the second flexible circuit board together; and reflowing the solder composition with a heat source to bond the first flexible circuit board and the second flexible circuit board together to form a flexible circuit board strip having a length longer than either of the first flexible circuit board or second flexible circuit board separately. In an embodiment the invention includes a circuit board clamp for holding flexible circuit boards together, the clamp including a u-shaped fastener; a spring tension arm connected to the u-shaped fastener; and an attachment mechanism connected to the spring tension arm. Other embodiments are also included herein.
Abstract:
A printed wiring board with a component connection pad, such as a solder pad, providing thermal stress compensation for a surface mount circuit component and method for making such a pad. The component connection pad includes opposed groups of multiple conductive fingers that are mutually connected at their far ends and separated at their near ends where they have surfaces for mounting a single surface mount circuit component.
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:
A spring finger interconnection system can include a plug and a receptacle. In one embodiment, the plug can include spring finger contacts configured to carry electrical signals. The receptacle can include a cavity to receive the plug and the cavity can be constructed with printed circuit board fabrication techniques. In one embodiment, the cavity can be formed, at least in part, in a pre-impregnation layer and a first and a second layer can be disposed above and below the pre-impregnation layer to further form the cavity. In one embodiment, contacts can be arranged on the first layer to contact the spring fingers when the plug is inserted into the cavity. In another embodiment, contacts can be arranged on both the first and the second layers. In yet another embodiment, the cavity can be shaped to aid in contact-to-spring finger alignment when the plug is inserted in the cavity.
Abstract:
The present invention relates to a partition post used on a printed circuit board, which comprises an insulation post member and an electric conductive spring. The top and the bottom of the insulation post member are respectively and protrudingly installed with an upper and a lower connection rings, and the bottom surface of the lower connection ring is longitudinally extended with an arrow-shaped elastic buckle claw; the electric conductive spring is sleeved on the insulation post member, the top and the bottom thereof are respectively installed with an upper and a lower guide parts composed of plural spiral rings and at the locations corresponding to the upper and the lower connection rings; so static electricity and/or noise signal generated by each electric component on the printed circuit board can be transmitted through the electric conductive spring to the electric conductive member and thereby providing a grounding effect.
Abstract:
A dual-personality extended USB (EUSB) system supports both USB and EUSB devices using an extended 9-pin EUSB socket. Each EUSB device includes a PCBA having four standard USB metal contact pads, and several extended purpose contact springs disposed on an upper side of a PCB. A single-shot molding process is used to form a molded housing over passive components and IC dies disposed on the lower PCB surface. The passive components are mounted using SMT methods, and the IC dies are mounted using COB methods. The extended 9-pin EUSB socket includes standard USB contacts and extended use contacts that communicate with the PCBA through the standard USB metal contacts and the contact springs. The EUSB device is optionally used as a modular insert that is mounted onto a metal or plastic case to provide a EUSB assembly having a plug shell similar to a standard USB male connector.
Abstract:
A conductive component includes a tubular body having at least one of at least one through-hole which penetrates the tubular body from outside to inside thereof; and at least one notch which is cut in from an edge of the tubular body, which are formed at least one predetermined portion on the tubular body. The tubular body includes a first portion, which includes a solder joint portion, and a second portion, which includes a contact portion. The first portion and the second portion are located on the opposite sides from one another with the at least one predetermined portion sandwiched therebetween. The tubular body further includes at least one spring portion which includes the at least one predetermined portion.
Abstract:
The present invention discloses an electrical device with a connection interface, a circuit board thereof, and a method for manufacturing the same. The electrical device with a connection interface includes: a circuit board on which a first circuit layer and a second circuit layer are formed and the second circuit layer has plural terminal pads, wherein a cavity is formed in the terminal pads and extends to the first circuit layer, and a metal layer is disposed in the cavity and connected to the first circuit layer and the terminal pads and defines an opening; a semiconductor chip electrically connected to the first circuit layer; and a conductive element interlaid in the opening. The electrical device with a connection interface does not need to be formed by assembling a terminal module because the conductive element is directly mounted on the circuit board.
Abstract:
An electronic component has an integrated protective device which responds in the event of a thermal overload and interrupts a current flow through the component. The protective device has an electrical terminal which may be brought under spring pretension by intrinsic resilience and assumes a mounting position in the pretensioned state and a current interrupting position in the untensioned state.
Abstract:
A structure for use with data network management systems uses a plurality of cables interconnecting patch panels, network devices and end-user devices and further utilizes integrated circuits to monitor the status of these end-user devices. The structure includes respective primary (36) and secondary (45) circuit boards. A plurality of connective jacks (31) are mounted on the primary circuit board and these jacks are interconnected to switches and other patch panels within the network. Wires from the jacks extend to and connect with end-user devices and a secondary circuit board is spaced apart from the primary circuit board so as to define a hollow nest (42) within the patch panel assembly that houses and protects integrated circuits (45, 52) and the like.
