Doubling available printed wiring card edge for high speed interconnect in electronic packaging applications

摘要

An interconnection assembly for a motherboard uses right-angle edge connectors attached to a bottom side of the motherboard, and vertical header connectors attached to the top side. The header connectors mate with a transition card assembly which includes a transition card having plated through holes that receive pins of the header connectors. Right-angle mezzanine connectors mounted on the transition card have pins that extend into the plated through holes from the top side. The edge connectors and mezzanine connectors both face forward in a common direction. The transition card has holes along a rear edge to retain pressed-in nuts for mounting to a stabilizing bezel. Instead of pins being part of the header connectors, connector caps may be provided with pins having first ends that extend into sockets of the header connectors and second ends that extend into the plated through holes of the transition card.

主权项

1. An electronic interconnection assembly comprising:
a first circuit board having first and second opposing surfaces and at least one edge defining a forward area in front of said circuit board; a first right-angle connector mounted to said first surface of said first circuit board proximate said edge, providing electrical connections with a first plurality of connection points on said first surface of said first circuit board, and having a first interconnect facing toward said forward area; a header connector mounted to said second surface of said first circuit board proximate said edge, providing electrical connections with a second plurality of connection points on said second surface of said first circuit board, and having a first plurality of pins extending away from said second surface of said first circuit board; a second circuit board having first and second opposing surfaces and a plurality of plated through holes which receive said first plurality of pins along said first surface of said second circuit board, wherein said first and second circuit boards are generally parallel; and a second right-angle connector mounted to said second surface of said second circuit board having a second plurality of pins which are received by said plated through holes along said second surface of said second circuit board, and having a second interconnect facing toward said forward area.
