A connector for use with high speed signals. The connector may include lead frame assemblies in a connector housing. A lead frame assembly may include signal conductive elements and ground conductive elements disposed in a repeating pattern, and one or more corrugated sheets attached to the ground conductive elements. The corrugated sheets may extend more than half of the length of the signal conductive elements. Valleys of the corrugated sheets may be welded to the ground conductive elements with line welds. The line welds may extend over a large percentage of the length of the conductive elements. Such a configuration enables accurately and repeatedly establishing signal to ground spacing and therefore promotes high signal integrity, even for miniaturized connectors. Such a connector may be used to meet signal integrity requirements in connectors designed for 112 GBps and beyond.

Miniaturized high speed connector

A printed circuit board includes a dielectric substrate; first and second conductive traces disposed on the dielectric substrate; and a compensation structure disposed in the first conductive trace. The compensation structure includes a compensation segment connected in line with the first conductive trace; and a dielectric layer on all or part of the compensation segment. The first and second conductive traces may form a differential signal pair. The compensation segment may limit one or more of signal skew, mode conversion from differential mode to common mode, and impedance variations caused by a bend in the differential signal pair.
