An electrical connector includes a housing (12) and circuit boards (13) carried by the housing. The circuit boards extend parallel to each other in spaced-apart relationship. The circuit boards include signal tracks (14) that provide electrical paths through the connector. The electrical
A printed circuit board includes a bore having a perimeter and a total depth. An electrically conductive barrel extends around at least a portion of the perimeter of the bore and along a predetermined depth of the bore, the predetermined depth being less than the total depth of the bore.
A multi-layer circuit board is provided that simultaneously optimizes impedance and interference within the multi-layer circuit board and a controlled impedance connector to which it is attached. The multi-layer circuit board includes at least one signal circuit layer, a plurality of
An electrical connector includes a housing (12) including a front housing portion (20) having a front wall (21) and a plurality of parallel apertures (22) extending through the front wall. A plurality of circuit boards (13) extend through respective ones of the apertures. Each of the
An electrical connector includes a housing (12) that carries a plurality of circuit boards (13) in a parallel, spaced-apart array. The circuit boards are of two different types. One type has a keying recess (60) that is keyed to a land (39) in the housing, and the other type has a keying
