摘要： A circuit board includes a first and second ground layer and a plurality of signal vias extending between the ground layers but not electrical contact therewith. Ground vias coupled to the first and second ground layers can be positioned adjacent signal vias and can include ground traces that extend between adjacent ground vias. Air holes can be positioned between signal vias and/or adjacent signal vias to modify the electrical performance of the circuit board. Ground wings can be used to help tune common-mode and/or differential-mode impedances.

摘要： An edge connector is provided for a printed circuit board having a mating edge and a plurality of contact pads adjacent the edge. The connector includes an elongated dielectric housing having a board-receiving slot for receiving the mating edge of the printed circuit board. A plurality of spring contact elements are mounted in the housing along at least one side of the slot. The spring contact elements have spring contact portions extending into the slot for contacting respective ones of the contact pads on the printed circuit board. A surface on the housing at the one side of the slot defines a datum plane beyond which the spring contact portion of at least one of the spring contact elements extends into the slot. A biasing spring on the housing biases the printed circuit board against the surface, thereby deflecting the spring contact portion of the at least one spring contact element a predetermined amount.

摘要： A pedestal connector that incorporates one or more grouped element channel link transmission lines is seen to have a dielectric body and two opposing contact ends that are intended to contact opposing contacts or traces. The dielectric body has an S-shaped configuration such that the transmission lines supported thereon make at least one change in direction, thereby permitting the use of such connector to interconnect elements lying in two different planes. The transmission lines include slots that extend within the frame and which define opposing, conductive surfaces formed on the dielectric body which are separated by an intervening air gap.

摘要： A terminal contact arrangement for a connector promotes reduction in deviation of the impedance of the connector when mated to an opposing connector and energized. The connector has an insulative housing with a plurality of terminal-receiving passages disposed in it. Conductive terminals are supported in some, but not all of the passages. The terminal contain distinct terminal sets that include a pair of differential signal terminals and at least two associated ground reference terminals. The two associated ground reference terminals are interconnected together so that electrically, they act as a single ground terminal having a width equal to the sum of the widths of the two connected ground reference terminals. The ground reference terminals of the sets are disposed in a single row of terminals, while the differential signal terminals of the same terminal set are disposed in another row of terminals spaced apart from the row of ground reference terminals. The differential signal terminals are separated from each other within their terminal row by an empty passage so that the two differential signal terminals of each terminal set are spaced farther apart from each other than they are spaced apart from their associated ground reference terminals.

摘要： A termination structure for mating a cable connector to a circuit board has a ground terminal and two signal terminals arranged in triangular pattern through the connector in order to reduce the impedance through the connector. The width of the ground terminal increases along its extent with respect to the signal terminals. This increase occurs along either a transition or contact portion of the ground terminal.
