Abstract: A process and apparatus for producing supported conductive networks which can be flexible or rigid, having densely packed circuits. The process and apparatus for making the conductive network involves forming a conductive material supported on a "dynamic pressure cushion" into a non-planar pattern defining the desired conductive circuits in relation to a fixed reference plane. The "dynamic pressure cushion" is a material having suitable viscosity and flow characteristics to flow out from under the conductive material as it is being formed and fill up any voids. To ensure that the "dynamic pressure cushion" properly flows without deforming the desired circuits, the die used to form the conductive material is provided with a material flow control grid and material expansion troughs. After forming the unwanted material is then mechanically removed in dimensional relation to the reference plane leaving the desired conductive circuits.

Abstract: A conductive network, which can be flexible or rigid, can have self-aligning conductors which connect with corresponding conductors of other networks. The conductive network can be fabricated into densely packed contact clusters for use as electrical interconnectors or circuits. The contact clusters, which can be configured to substantially any shape, are the essential components of high density connector assemblies. The methods and apparatus for making the conductive network and cluster contacts are also described.
