Abstract:
A printed circuit board assembly includes two-dimensional arrays of connectors (14,16) to provide significantly higher data transfer rates than typical one-dimensionally arranged connectors, without sacrificing board space. The assembly includes a plurality of connection pads (14,16) on each printed circuit board (10,12). A layer of anisotropically conducting material (26) is placed between the connection pads and the boards are held together by fastening screws (28).
Abstract:
An electrical connection system, for example a drop-side patch panel, comprises a mounting rail (12) which receives first connectors (14) arranged with their contacts facing away from the rail (12). Cable introduced between the rail and the connectors is separated into individual conductors which are terminated at contacts (34, 36) via slots (30) in the rail walls. A second connector (16) carries standard data or voice sockets communications (19) which are connected to the first connector via edge contact carrying PCBs (38) which engage in slots (40) in the first connectors. The PCB edge connectors have a discontinuity on one surface, and one half of the contact is connected to the contact on the other side to enable direct connection between upper (34) and lower (36) rows of contacts of the first connectors in a first position of the second connectors, and contact between the upper rows of contacts and the standard sockets (19) in a second position.

Abstract:
An insulation displacement contact comprises first and second contact portions each of which comprises a cantilevered split beam. The upper split beam, which receives insulated wires, comprises a pair of tynes which are folded about the axis of a slot separating the tynes such that the internal angle between the tynes is approximately 90°. The width of the tynes is larger than that of prior art devices resulting in increased stiffness and the length of the tynes is sufficiently long to receive two wires therebetween. The contacts are mounted in a housing which includes a plurality of teeth provided with means for retaining lugs on the end of the tynes to ensure bowed opening of the tynes on insertion of a wire. The contacts are arranged along the central axis of the housing such that the folded tynes of alternate contacts extend on opposite sides of the central axis.

An insulation displacement contact (10) comprises first and second contact portions each of which comprises a cantilevered split beam (19). The upper split beam, which receives insulated wires, comprises a pair of tynes (20,22) which are folded about the axis of a slot (25) separating the tynes such that the internal angle between the tynes is approximately 90°. The width of the tynes is larger than that of prior art devices resulting in increased stiffness and the length of the tynes is sufficiently long to receive two wires therebetween. The contacts (10) are mounted in a housing which includes a plurality of teeth (90) provided with means for retaining lugs (32,34) on the end of the tynes to ensure bowed opening of the tynes on insertion of a wire. The contacts are arranged along the central axis (72) of the housing such that the folded tynes of alternate contacts extend on opposite sides of the central axis.
Abstract:
Contact autodénudant comprenant une première et une deuxième partie de contact, dont chacune comporte un profilé en porte-à-faux divisé. Le profilé divisé supérieur recevant les fils isolés comprend une paire de dents pliées autour de l'axe d'une fente séparant lesdites dents de telle sorte que l'angle interne entre celles-ci soit d'environ 90°. La largeur des dents est plus importante que celle qui caractérise les dispositifs de la technqiue antérieure, ce qui entraîne une rigidité accrue et leur longueur est suffisamment importante pour placer deux fils entre elles. Les contacts sont montés dans un boîtier qui comprend plusieurs dents munies d'un moyen destiné à retenir des têtons à l'extrémité des dents de façon à permettre l'ouverture courbée des dents lors de l'indroduction d'un fil. Les fils sont disposés le long de l'axe central du boîtier de telle sorte que les dents pliées de contacts alternés s'étendant sur les côtés opposés de l'axe central.
Abstract:
An integrated circuit die (1) is disclosed that comprises a substrate (30) defining a plurality of circuit elements; a sensor region (10) on the substrate, the sensor region comprising a layer stack defining a plurality of CMUT (capacitive micromachined ultrasound transducer) cells (11); and an interposer region (60) on the substrate adjacent to the sensor region. The interposer region comprises a further layer stack including conductive connections to the circuit elements and the CMUT cells, the conductive connections connected to a plurality of conductive contact regions on an upper surface of the interposer region, the conductive contact regions including external contacts (61) for contacting the integrated circuit die to a connection cable (410) and mounting pads (65) for mounting a passive component (320) on the upper surface. A probe including such an integrated circuit die an ultrasound system including such a probe are also disclosed.

Abstract:
Provided is a printed circuit board including a base substrate, first row pads, and second row pads. The base substrate has two sides, that can be adjacent, respectively extending in first and second directions. A plurality of pad group areas successively positioned along the first direction are defined on the base substrate. The first row pads are respectively disposed within the pad group areas and successively positioned along a third direction. The second row pads are respectively disposed within the pad group areas, successively positioned along the third direction, and spaced apart from the first row pads. Each of the second row pads is a predetermined distance from a corresponding one of the first row pads in the second direction.
