Abstract:
A high speed connector assembly includes a first surface-mount connector (SMC) and a second SMC. The first SMC includes a first flexible printed circuit (FPC) that has conductors that extend from a first FPC edge to a second FPC edge. The first edge includes surface-mount contact structures for surface mounting to a first printed circuit board. The second SMC includes a second FPC that has conductors that extend from a first FPC edge to a second FPC edge. The first edge includes surface-mount contact structures for surface mounting to a second printed circuit board. A set of contact beams is disposed along the second FPC edge. The first and second SMCs are mateable such that the contact beams make electrical contact between conductors in the first FPC and conductors in the second FPC. The FPC of the second SMC flexes to adjust for misalignments between the first and second SMCs.

An electrical component including a substrate having opposite first and second sides and a plurality of vias extending into the substrate from the first side. The substrate has first conductive pads on the first side that are electrically connected to corresponding vias. The electrical component also includes a plurality of electrical contacts that are mounted to the substrate along the first side. Each of the electrical contacts includes a contact heel and a contact beam that extends from the corresponding contact heel and at least partially away from the first side. The contact heels are laser-welded to corresponding first conductive pads.
Abstract:
A circuit board including a board substrate having opposite first and second sides. The board substrate has a thickness measured along a z-axis that is perpendicular to the first and second sides. The circuit board also includes plated thru-hole (PTH) vias extending along the z-axis from the first side into the board substrate. The PTH vias are arranged to form multiple signal pairs. The circuit board also includes signal traces that are directly coupled to the PTH vias and extend perpendicular to the z-axis in the board substrate. The signal traces and the PTH vias are configured to transmit differential signals. The circuit board also includes ground columns that extend along the z-axis in the board substrate. The ground columns are distributed relative to the signal pairs to form shield arrays. Each of the shield arrays surrounds one of the signal pairs, wherein the ground columns comprise microvias.

A land grid array interconnect has a substrate that has a first surface and a second surface. The substrate has a plurality of vias extending therethrough. The substrate has first pads on the first surface electrically connected to corresponding vias and has second pads on the second surface electrically connected to corresponding vias and corresponding first pads. A contact array is coupled to the first surface of the substrate. The contact array has a metal plate that defines a carrier and a plurality of contacts formed from the metal plate and held by the carrier. The contacts have contact heels and beams extending from corresponding contact heels. The contact heels are soldered to corresponding first pads. The contacts are singulated from the carrier after the contact heels are soldered to the first pads. The carrier is removed from the substrate after the contacts are singulated leaving the individual contacts soldered to corresponding first pads.

Abstract:
A connector assembly includes a male connector and a female connector. The female connector includes two printed circuit assembly portions (PCAPs). Each PCAP includes a printed circuit having a ground plane and a plurality of conductors. A plurality of contact beams are attached to the conductors so that the PCAP structure resembles a comb. The two PCAPs are disposed in an insulative portion of the female connector such that the two rows of contact beams face one another. The male connector also includes two PCAPs. The PCAPs in the male connector do not have contact beams but rather have exposed conductors. When the male and female connectors are mated, the contact beams on the female connector make contact with the exposed conductors on the PCAPs in the male connector. The structure of the PCAPs in the assembly are microstrip-like and the characteristic impedance through the mated connectors is substantially uniform.

An electrical connector includes a housing and a contact held by the housing. The contact has a mating interface configured for mating with a mating contact of a mating connector. The contact has a planar side extending to a tip. An interface contact is separately provided from, and coupled to, the mating interface of the contact. The interface contact has a base coupled to the side of the contact proximate to the tip. The interface contact has a spring beam extending from the base away from the side of the contact. The spring beam is configured to engage the mating contact of the mating connector to make an electrical connection between the contact and the mating contact.
