An electrical interconnect for passing high speed signals through an electronic system with a high density of signals and high signal integrity. The interconnect includes an electrical connector and a transition portion of a printed circuit board to which the connector is mounted. Signal conductors are connected to pads on the surface of the PCB using edge-to-pad mounting. The pads align with intermediate portions of the signal conductors such that transitions within the connector that could degrade signal integrity are avoided. The signal conductors may be positioned as individually shielded broadside coupled pairs extending in rows within the connector. Surface traces on the PCB connect the pads to signal vias aligned for vertical routing out of the connector footprint. Ground planes underlying the surface traces facilitate a transition from the signal paths in the connector to those in the PCB with low mode conversion avoiding resonances in the connector shields.

Electrical connector with high speed mounting interface

A printed circuit board includes a plurality of layers including attachment layers and routing layers; and via patterns formed in the plurality of layers, each of the via patterns including first and second signal vias forming a differential signal pair, the first and second signal vias extending through at least the attachment layers; ground vias extending through at least the attachment layers, the ground vias including ground conductors; and shadow vias located adjacent to each of the first and second signal vias, wherein the shadow vias are free of conductive material in the attachment layers. The printed circuit board may further include slot vias extending through the attachment layers and located between via patterns.

Mating backplane for high speed, high density electrical connector

A modular electrical connector with broad-side coupled signal conductors in a right angle intermediate portion. Broadside coupling provides balanced pairs for very high frequency operation. The connector is assembled with multiple subassemblies, each of which has multiple pairs of signal conductors. The subassemblies are formed from an insulative portion having grooves in opposite sides into which the intermediate portions of signal conductors. Covers, holding the signal conductors in the grooves, establish the position of the signal conductors relative to reference conductors at the exterior of subassembly, so as to provide a controlled impedance. Lossy material is positioned between the pairs in a subassembly and/or contacts the reference conductors of the subassemblies, and the lossy material of the subassemblies is in turn connected with a conductive structure.

Electrical connector

A modular electrical connector with modular components suitable for assembly into a right angle connector may also be used in forming an orthogonal connector or connector in other desired configurations. The connector modules may be configured through the user of extender modules. Those connector modules may be held together as a right angle connector with a front housing portion, which, in some embodiments, may be shaped differently depending on whether the connector modules are used to form a right angle connector or an orthogonal connector. When designed to form an orthogonal connector, the extender modules may interlock into subarrays, which may be held to other connector components through the use of an extender shell. The mating contact portions on the extender modules may be such that a right angle connector, similarly made with connector modules, may directly mate with the orthogonal connector.

Extender module for modular connector

A modular electrical connector with separately shielded signal conductor pairs. The connector may be assembled from modules, each containing a pair of signal conductors with surrounding partially or fully conductive material. Modules of different sizes may be assembled into wafers, which are then assembled into a connector. Wafers may include lossy material. In some embodiments, shielding members of two mating connectors may each have compliant members along their distal portions, such that, the shielding members engage at points of contact at multiple locations, some of which are adjacent the mating edge of each of the mating shielding members.

High speed, high density electrical connector with shielded signal paths preliminary class

A printed circuit board includes a plurality of layers including conductive layers separated by dielectric layers; and at least one via configured for solder attachment to a connector lead of a surface mount connector, the at least one via including a conductive element that extends from an upper surface of the printed circuit board through one or more of the plurality of layers, the conductive element having a recess in a surface thereof. The recess is configured to receive a tip portion of the connector lead of the surface mount connector. The printed circuit board may have via patterns including signal vias and ground vias.

Backplane footprint for high speed, high density electrical connectors

Connector assemblies for making connections to a subassembly, such as a processor card, may include signal contact tips formed of a material different than that of an associated cable conductor. The signal contact tips may be formed of a super elastic material, such as nickel titanium. The connector assembly may include ground contact tips that similarly make a pressure contact to the electrical component may be electrically connected to a shield of the cable shield Housing modules that interlock or interface with a support member may be employed to manufacture connectors with any desired quantity of signal and ground contact tips in any suitable number of columns and rows. Each module may terminate a cable and provide pressure mount connections between signal conductors and the shield of the cable and conductive pads on the subassembly, and conductive or lossy grounded structures around the conductive elements carrying signals through the module.

High speed electronic system with midboard cable connector

A modular high speed, high density electrical connector configurable for use in multiple configurations, including a direct attach orthogonal configuration. The connector is assembled with modules that include shielded pairs of signal conductors with mating ends that are rotated approximately 45 degrees with respect to intermediate portions of the signal conductors. The connector may have a mating interface with receptacles in one connector and pins in the mating connector. The pins may be small diameter and may be implemented with superelastic wires so as to resist damage despite having very small effective diameter. A compact mating interface resulting from small diameter mating contact portions may enable other portions of the connector, including the shielding surrounding the signal conductors to be smaller, which may raise the resonant frequency of the connector and extend its bandwidth.

High density, high speed electrical connector

A broadside coupled connector assembly has two sets of conductors, each separate planes. By providing the same path lengths, there is no skew between the conductors of the differential pair and the impedance of those conductors is identical. The conductor sets are formed by embedding the first set of conductors in an insulated housing having a top surface with channels. The second set of conductors is placed within the channels so that no air gaps form between the two sets of conductors. A second insulated housing is filled over the second set of conductors and into the channels to form a completed wafer. The ends of the conductors are received in a blade housing. Differential and ground pairs of blades have one end that extends through the bottom of the housing having a small footprint. An opposite end of the pairs of blades diverge to connect with the wafers. The ends of the first and second sets of conductors and the blades are jogged in both an x- and y-coordinate to reduce crosstalk and improve electrical performance.

High speed, high density electrical connector

A modular electrical connector facilitates low loss connections to components on a printed circuit board. A portion is of the connector is formed of one or more first type units with conductive elements designed to be attached to a printed circuit board. Signals passing through those units may be routed to components on the printed circuit board through traces in the board. One or more second type units may be integrated with the connector. Those units may be designed for attachment to a cable, which may provide signal paths to a location on the printed circuit board near relatively distant components.
