Abstract: Electrical connector including a connector body having a mating side configured to interface with an electrical component. The electrical connector also includes signal pathways extending through the connector body. The signal pathways are arranged to form pairs of signal pathways. The electrical connector also includes an impedance-control assembly having a plurality of dielectric bodies supported by the connector body. The dielectric bodies surround respective pairs of signal pathways. The dielectric bodies include a dielectric medium and gas bubbles distributed in the dielectric medium. The dielectric medium has a predetermined dielectric constant. The at least one of the gas bubbles or gas-filled particles are sized and distributed in the dielectric medium to achieve a target dielectric constant of the dielectric bodies.

Abstract: Connectors and/or substrates which are made utilizing a low dielectric constant injection moldable polymer or other melt processable polymer, such as, but not limited to, thermoplastic material, thermoplastic composite material, thermoset material, thermoset composite material or a combination thereof. The low dielectric constant injection moldable polymer or other melt processable polymer support noise and/or crosstalk reductions for high speed signal transmission. The low dielectric constant material provides dielectric shielding between adjacent high speed signal lines. The reduced dielectric constant and reduced loss-tangent is created by forming voids or pores within the bulk plastic material, thus increasing the air, gas or void content, and thus decreasing the density and overall dielectric constant of such material. The porosity thus introduced into the shielding between adjacent transmission lines reduces crosstalk and other losses, and thus maintains signal integrity in connector/substrate designs.
