High density electrical connectors

Abstract

The present invention relates to self-aligned, flexible high density and impedance adjusted electrical connectors used in microelectronic systems. This invention solves the problem of having electrical connection and alignment at the same time. One connector (200) having a first part (204) consists of two metal layer structures, a first signal path (212) and a first ground path (210), covering the V-groove (202). The connector also has a second part (208) consisting of corresponding metal layers, a second signal path (224) covering the elastic bump (206) and a second signal ground plane (226), which fits into the V-groove (202). The first and the second signal path (212, 224) are in contact with each other when the first and the second part (204, 208) are brought together. The contact is self-aligned when put together. The electrical contact will remain even if displaced due to the thermal expansion.

Description

technical field [0001] This invention relates to the interconnection of electrical devices and, more particularly, to self-aligning deformable high density electrical connectors with adjustable impedance. Background technique [0002] Technological developments in the field of integrated circuits (ICs) have created a demand for faster and more compact systems. Lightweight and compact construction is a requirement in itself in many applications. Technological development also tends towards more complex systems, which include more and more components that need to be connected to each other. In order for the new system to meet the requirements for fast access between the different components, the length of the paths between the different components of the system must be kept within certain limits. [0003] As the complexity of the system increases, the length of the paths between components also increases. In order not to exceed the maximum usable distance between these part...

Problems solved by technology

As density increases, alignment requirements increase, and the higher this requirement becomes, the more important it is to use self-alignment because of the increased cost of high-precision active alignment acceleration

[0007] When connecting different parts of a complex system, as the complexity of the system increases, so does the danger of having to replace some or more of these parts in order to obtain an efficient system

Increased difficulty in adequately testing components at relevant frequencies and operating conditions
