Abstract:
A plug contact for electrically contacting a circuit board by inserting the plug contact into a via hole in the circuit board, the plug contact having two flat contact arms that are resilient relative to each other, and a connecting region, from which the two contact arms extend in the plug-in direction of the plug contact, the plug contact being punched as a single piece from a flat metallic material. In the connection region, adjacent to the two contact arms, a recess is formed in the plug contact, the distance between the two contact arms increases from the recess towards the free ends of the contact arms, the two contact arms being spread apart relative to each other and the two contact arms together having a width which is the same as or only slightly smaller than the diameter of the corresponding via hole in the circuit board.
Abstract:
An electronic device for a motor vehicle includes a metal tubular casing extending longitudinally and opening at its two ends, and a wall having a curved profile with cooling fins on its outer surface. The electronic device includes an assembly of printed circuit boards comprising a first plurality of printed circuit boards that include heat-generating electronic components. The printed circuit boards of the assembly are connected together by flexible conductive elements. The device further comprises a first heat sink arranged inside the tubular casing comprising a curved wall generally extending parallel to the curved wall of the tubular casing. The first plurality of printed circuit boards is interposed between the curved inner surface of the wall of the casing and the curved wall of the first heat sink so heat is dissipated through the first heat sink and through the curved wall equipped with cooling fins of the tubular casing.

A touch screen panel includes: a touch sensor film including: at least one corner formed in a curved line; and a through part; and a flexible printed circuit board including one end connected to a wiring extending from the touch sensor film; the flexible printed circuit board disposed through the through part, wherein the through part is disposed adjacent to the corner of the touch sensor film formed in the curved line, and wherein the through part includes a curved line corresponding to the corner of the touch sensor film formed in the curved line.
Abstract:
According to exemplary embodiments, a tapered surface interconnect is formed on a printed circuit board (PCB). A compliant pin of an electrical connector may be coupled to the tapered surface interconnect and soldered thereto. The surface interconnect may be formed by drilling through one or more layers of the PCB. The depth of the surface interconnect may be shorter than a height or a thickness of the PCB. The surface interconnect may have a tapered side wall to allow for a better fit with a tapered compliant pin. The inclination of the side wall of the surface interconnect may be linear or concave. The intersection between the tapered sidewall and the bottom of the surface interconnect may be rounded to minimize pin insertion issues and may allow for easier solder flux evacuation. The compliant pin may be soldered into place upon being coupled to the tapered surface interconnect.

Abstract:
A circuit board assembly includes a printed circuit board and a component. The printed circuit board includes a plated thru-hole through the printed circuit board. The component includes a lead to interconnect the component to the printed circuit board. The lead is formed to define an opening through the lead. The lead is placed into the plated thru-hole such that at least part of the opening is within the plated thru-hole. The lead is laser welded to the plated thru-hole.
Abstract:
A circuit board includes a board body of a thickness, and a socket. The board body defines a plurality of through holes therein. The socket includes a first line of short pin groups and a second line of long pin groups engaging the through holes of the board body. The socket defines a slot. The first line of short pin groups and the second line of long pin groups are respectively located on opposite sides of the slot. The first line of short pin groups has a length less than the thickness of the board body. The second line of long pin groups has a length sufficient that the second line of pin groups protrudes the board body.
Abstract:
Improved printed circuit boards (PCBs), printed circuit board assemblies (PCBAs) and methods thereof contemplate PCBs with recesses incorporated into planar surfaces thereof adapted to receive respective elongate leads of circuit components. The recesses are sized so as to prevent distal ends of the leads from emerging through the far sides of the boards and, indeed, allow for positioning of the component flush with, or offset above, the board to which they are mounted.
Abstract:
An electronic device is mounted on a wiring board, which includes: a substrate having through holes, and lands extending on surfaces of the substrate and adjacent to openings of the through holes. Further, at least one coating layer is provided, which coats at least one part of an outer peripheral region of the at least one land, in order to cause that the at least one part is separated from a lead-less solder, thereby preventing any peel of the land from the surface of the substrate.
