Abstract: A method for making electrical interposers which includes the use of a stencil which is thicker than designated lower contact pads and which defines a stencil passage corresponding to each lower contact pad of each interposer. The stencil is attached to a bottom surface of an insulative layer and a conductive elastomeric material is applied to the stencil, so that the stencil passages are filled with said conductive elastomeric material. When this material has been adequately placed within the stencil passages the stencil is removed thus leaving each lower conductive pad with an attached conductive elastomeric pad.

Abstract: An interposer with a contact well, a layer that isolates one side of the interposer from the other side, for isolations of off gasses, and an optional elastomeric pad and a hard stop layer. Included is a method of making the interposer.

Abstract: An improved interposer and method for making an interposer, for use in forming an electrical connection between electrical components. The interposer includes a bi-lobate contact pad made of an elastomeric material embedded with conductive metallic granules.

Abstract: A method of making a socket test probe which results in a probe head which has flat plates which serve as electrodes encased in resin. The electrodes are conductive plates with one or more edges of the conductive plates exposed for connection to the electrodes of a socket. The entire probe head starts as a solid block of conductive material which is drilled, machined, filled with resin and machined again to form a socket testing probe utilizing the edges of conductive plates as electrodes.

Abstract: An alignment system for positioning a socket test probe in a socket of a printed circuit board to be tested. The socket test probe is self-aligning in the socket by use of a free-floating ball joint enclosed in a ball joint housing. The socket test probe is connected through a probe body to the ball joint, and is held in an immobilized position until it is ready to enter a socket. When entering a socket, the probe body is free floating about the ball joint, and the socket test probe aligns itself for entry into the socket by friction between the socket and the socket test probe. A clamp on the probe body immobilizes or frees the probe body with its attached socket test probe. The clamp is activated by air pressure.
