U-Channel Coaxial F-Connector

An F-connector for a coaxial cable comprises a front insulator, a back insulator, a connecting lead, and a locking ring. The connecting lead has an interior portion and an exterior portion. The interior portion is configured with a pair of side wall portions which are parallel to each other, and which together with a bottom portion form a U-shaped channel. The side wall portions each comprise a curved portion that are configured to grip the center conductor of the coaxial cable so as to withstand a certain level of withdrawal force, and such that the F-connector exhibits a desired impedance of 75 Ohms. The connecting lead engages with the front insulator and the back insulator such that the components are held in position within a connector body.

High speed high density electrical connector

An electrical connector includes a wafer formed with a ground shield made from a non-conductive material made conductive with conductive particles disposed therein, thereby eliminating the necessity of the metal ground shield plate found in prior art connectors while maintaining sufficient performance characteristics and minimizing electrical noise generated in the wafer. The wafer housing is formed with a first, insulative housing at least partially surrounding a pair of signal strips and a second, conductive housing at least partially surrounding the first, insulative housing and the signal strips. The housings provide the wafer with sufficient structural integrity, obviating the need for additional support structures or components for a wafer. Ground strips may be employed in the wafer and may be formed in the same plane as the signal strips. The second, conductive housing may be connected (e.g., molded) to the ground strips and spaced appropriately from the signal strips. The wafer may also include air gaps between the signal strips of one wafer and the conductive housing of an adjacent wafer further reducing electrical noise or other losses (e.g., cross-talk) without sacrificing significant signal strength.

Method and apparatus for shaping spring elements

Interconnection elements for electronic components, exhibiting desirable mechanical characteristic (such as resiliency, for making pressure contacts) are formed by using a shaping tool (512) to shape an elongate core element (502) of a soft material (such as gold or soft copper wire) to have a springable shape (including cantilever beam, S-shape, U-shape), and overcoating the shaped core element with a hard material (such as nickel and its alloys), to impart to desired spring (resilient) characteristic to the resulting composite interconnection element. A final overcoat of a material having superior electrical qualities (e.g., electrical conductivity and/or solderability) may be applied to the composite interconnection element. The resulting interconnection elements may be mounted to a variety of electronic components, including directly to semiconductor dies and wafers (in which case the overcoat material anchors the composite interconnection element to a terminal (or the like) on the electronic component), may be mounted to support substrates for use as interposers and may be mounted to substrates for use as probe cards or probe card inserts. The shaping tool may be an anvil (622) and a die (624), and may nick or sever successive shaped portions of the elongate elements, and the elongate element may be of an inherently hard (springy) material. Methods of fabricating interconnection elements on sacrificial substrates are described. Methods of fabricating tip structures (258) and contact tips at the end of interconnection elements are also described.

Electrical connector with hybrid shield

An electrical connector with reduced cross talk and controlled impedance. The connector comprises hybrid shields with lossy portions and conductive portions. The synergistic effect of the lossy portions and the conductive portions allows the hybrid shields to be relatively thin such that they can be incorporated into the mating interface regions or other mechanically constrained regions of the connector to provide adequate crosstalk suppression without undesirably impacting impedance. The conductive portions may be shaped to preferentially position the conductive regions adjacent signal conductors susceptible to cross talk to further contribute to the synergy. The conductive regions may include holes to contribute to desired electrical properties for the connector.
