Abstract:
A lightweight radio/CD player for vehicular application includes a case and frontal interface formed of polymer based material molded to provide details to accept audio devices and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips.

In the tape attaching method of cutting a tape member into conductive tape pieces and attaching the conductive tape pieces onto a plurality of attachment regions which are formed at a side edge part of a board, an attaching step in which the conductive tape pieces is attached onto the attachment region of a first press position, and a moving step, in which by driving a tape sending mechanism to perform the operation of sending the tape member while a press bonding head and a peeling unit are integrally moved relative to the board, the press bonding head is aligned with the attachment region of a second press position, and a separator is peeled from the tape member attached onto the first press position by the peeling unit during the relative movement, are repeated.
Abstract:
An improved method for producing a PCB assembly requiring at least two different encapsulants is disclosed. The PCB assembly may have two or more separate regions in which electronic devices are attached. In each region, a unique encapsulant with different mechanical, electrical, physical and or chemical properties is used according to the particular requirements of the electronic devices in that region.
Abstract:
Printed circuit boards are provided with embedded components. The embedded components may be mounted within recesses in the surface of a printed circuit board substrate. The printed circuit board substrate may have grooves and buried channels in which wires may be mounted. Recesses may be provided with solder pads to which the wires may be soldered or attached with conductive adhesive. An integrated switch may be provided in an opening within a printed circuit board substrate. The integrated switch may have a dome switch member that is mounted within the opening. A cover member for the switch may be formed from a flexible layer that covers the dome switch member. Terminals for the integrated switch may be formed from conductive structures in an interior printed circuit board layer. Interconnects may be used to electrically connect embedded components such as switches, integrated circuits, solder pads for wires, and other devices.

Abstract:
The present invention discloses a connector, PCB for LED Light Bar and LED Light Bar. The connector comprises the weld legs and stitches fixed to the shell of the connector, and the weld legs are arranged on the side of the connector and are higher than the bottom surface. A PCB for LED light bar is provided with the installing groove for installing the connector. Because the present invention arranges the weld legs of the connector on positions which are higher than the bottom surface of the shell and arranges the installing groove corresponding to the bottom shape of the connector on the PCB, the bottom of the connector can be arranged in the installing groove, thus the protrusion height of the connector in the LED light bar is reduced. The LGP is not cut again when installing the LGP, thereby reducing the processing step. In addition, the depth that the connector sinks into the installing groove is rationally designed, so that the sufficient safe distance is remained when the LGP is heated and expended, thereby avoiding the LGP bumping into and damaging the connector.

The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The PCB architecture integrally forms a resilient beam portion adjacent an edge thereof carrying a grounding pad.
Abstract:
A lightweight radio/CD player for vehicular application is virtually “fastenerless” and includes a case and frontal interface formed of polymer based material that is molded to provide details to accept audio devices such as playback mechanisms (if desired) and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides EMC, RFI, BCI and ESD shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The PCB architecture is bifurcated into a first board carrying common circuit components in a surface mount configuration suitable for high volume production, and a second board carrying application specific circuit components in a wave soldered stick mount configuration. The major components and subassemblies are self-fixturing during the final assembly process, eliminating the need for dedicated tools, fixtures and assembly equipment. The major components and subassemblies self-interconnect by integral guide and connection features effecting “slide lock” and “snap lock” self-interconnection. The radio architecture includes improved push buttons employing 4-bar living hinge linkage and front loaded decorative trim buttons.
Abstract:
A card edge connector for mating to a flex circuit includes a housing having a front, a top and a bottom. The housing has a slot between the top and the bottom. The slot is open at the front. The slot is configured to receive a flex circuit therein. Upper contacts are held by the housing between the slot and the top. The upper contacts are exposed in the slot for mating with an upper surface of the flex circuit. Lower contacts are held by the housing between the slot and the bottom. The lower contacts are exposed in the slot for mating with a lower surface of the flex circuit.
