Abstract:
A wiring substrate comprises an insulating substrate and an external electrode on the insulating substrate. The insulating substrate comprises a lateral surface comprising a cutout. The cutout extends to a lower surface of the insulating substrate. The external electrode extends from an inner surface of the cutout to the lower surface of the insulating substrate. The insulating substrate comprises a protrusion at a lower end portion of the inner surface of the cutout. The protrusion protrudes from the inner surface of the cutout toward the lateral surface of the insulating substrate.
Abstract:
An electric apparatus for connecting to a first printed circuit includes a second printed circuit, which includes a first surface substantially parallel to a first plane and a second surface substantially parallel to a second plane perpendicular to the first plane. The first surface includes a first area and the second surface includes a smaller second area. The second printed circuit includes conductive traces in a layer of the second printed circuit. The electric apparatus further includes first and second conductive pins including first and second longitudinal axes, respectively. First and second notches in the second printed circuit include respective first and second openings through the second surface adapted to receive portions of the first and second pins and adapted to electrically connect the pins to first and second respective ones of the conductive traces. The first and second longitudinal axes are installed substantially parallel to the first plane.
Abstract:
An electrical connector comprises an elongated flexible circuit having rigid strips bonded onto one or both sides and one or more ends thereof. The strips contain metallized castellations that are aligned with respective metal traces on the flex circuit and soldered thereto. The flexible portion, along with the attached rigid board(s) forms a plug assembly that mates with a socket having contact pins that engage with their respective metallized castellations, with the castellations providing a self-aligning function. The invention may be used to form a flex cable with connectors on one or both ends. Alternatively, the elongated flexible circuit may represent an extension of a larger flex circuit substrate that further contains other electronic devices mounted thereon. The socket and contact pins are preferably attachable to a motherboard by soldering or other means.

A terminal portion configured to obtain electrical connection with a printed circuit board includes a first signal pad that is formed in a first conductor layer and is electrically separated from a ground layer, a pair of first ground pads that is formed in the first conductor layer to sandwich the first signal pad and is connected to the ground layer, a second signal pad that is formed in a second conductor layer and is connected to a signal line, a pair of second ground pads that is formed in the second conductor layer to sandwich the second signal pad and is electrically separated from the signal line, a third signal pad formed in a third conductor layer, and a pair of third ground pads formed in the third conductor layer to sandwich the third signal pad. The second signal pad is wider than the third signal pad.
Abstract:
Communications plugs are provided which include a printed circuit board having a plurality of elongated conductive traces and a plurality of plug blades. Each plug blade has a first section that extends along a top surface of the printed circuit board and a second section that extends along a front edge of the printed circuit board. Additionally, each plug blade may have a thickness that is at least twice the thickness of the elongated conductive traces. The plug blades may be low profile plug blades that are manufactured separately from the printed circuit board.
Abstract:
Connector receptacles that have a reduced height when combined with a printed circuit board and reduce wasted space inside an electronic device. One example provides a connector receptacle having contacts that may connect to edge contacts along an edge of a printed circuit board. This edge may be formed along a side of printed circuit board, by a hole or opening in a printed circuit board, or by a notch in a printed circuit board. Edge contacts may have straight surfaces, rounded surfaces, or they may have other types of surfaces. Connector receptacle contacts may have a “U,” fishhook, or other shape.
Abstract:
An electronic device including a first ground conductor layer positioned at an underside of a first insulation layer; a second ground conductor layer positioned at an upper side of the first insulation layer; a second insulation layer positioned at an upper side of the second ground conductor layer; a first connection pattern formed in inside wall of a first opening penetrating the first insulation layer and the second insulation layer and interconnecting the first ground conductor layer and the second ground conductor layer; a conductive member provided in the first opening and connected to the first ground conductor layer; and an electronic element mounted on the member and grounded to the member.
Abstract:
Circuit boards are provided that include a functional portion and at least one removable test point portion. The removable test point portion may include test points which are accessed to verify whether the functional portion is operating properly or whether installed electronic components are electrically coupled to the board. If multiple boards are manufactured together on a single panel (in which the individual boards are broken off), the test points can be placed on bridges (e.g., removable portions) that connect the individual boards together during manufacturing and testing. Configurable test boards are also provided that can be adjusted to accommodate circuit boards of different size and electrical testing requirements. Methods and systems for testing these circuit boards are also provided.

A method and system for connecting a vertical printed circuit board with a horizontal printed circuit board where a contact device is biased in a first position when not contacting a vertical printed circuit board and is biased in a second position when the vertical printed circuit is coupled to the horizontal printed circuit board.
Abstract:
An electronic module adapted to be removably, operably connected to an electronic device. The electronic module includes a housing; at least one electronic component in the housing; and a plurality of electrical contact areas. The housing has a general electronic card shape with relatively large top and bottom sides and relatively thin side edges between the top and bottom sides. The plurality of electrical contact areas are located on a first one of the side edges. The electrical contact areas are connected to the at least one electronic component such that, when the electronic module is operably connected to the electronic device, the electrical contact areas on the first side edge are adapted to electrically couple the at least one electronic component to the electronic device along the first side edge.
