A system for batch forming a sheet of spring elements in three dimensions includes a top spacer layer. A plurality of ball bearings is arranged in a predetermined pattern on the top spacer layer. A spring element sheet containing the spring elements defined in two dimensions is positioned on the top spacer layer and the plurality of ball bearings.

An Anisotropic Conductive Elastomer (ACE)—based electrical connector that interconnects two or more electrical circuit elements. The connector includes at least two layers of ACE separated by alternate interconnection elements that include conductive elements. The conductive elements provide void space for the ACE elastomer to move to during the interconnection process.

An anisotropic conductive adhesive is provided that includes an epoxy resin, a phenoxy resin, a curing agent, an inorganic filler, and conducting particles as components. The phenoxy resin is controlled to have a glass-transition temperature (Tg) in a range of 66° C. to 100° C., so that the anisotropic conductive adhesive has an excellent fluidity in a mounting process, satisfactory electric conductive/insulation performances, and sufficient adhesiveness. Since the properties of the anisotropic conductive adhesive are almost invariant even if the adhesive is used for a long time under a high-temperature- and high-humidity condition, the anisotropic conductive adhesive can be used for applications where a high reliability is required.

A separable electrical connector for separably, electrically interconnecting the conductors of one multi-conductor cable to the conductors of a second electrical device that may be an electrical device such as a chip, or a second multi-conductor cable, or a flexible or rigid printed circuit board. The connector includes a layer of anisotropic conductive elastomer (ACE) in electrical contact with the conductors of the cable and the conductors of the second electrical device. A clamp or another type of mechanical device compresses the ACE, to provide electrical signal paths between the conductors of the cable and the second electrical device, through the ACE.

A novel, low profile connector element is disclosed for the purpose of electrically and mechanically interconnecting circuit elements in electronic devices, said circuit elements including but not limited to printed circuit boards, flexible printed circuits, rigid flex circuits, semiconductors, semiconductor package substrates, ground shields, and batteries, whereby the connector includes electrical contacts which have a unitary structure consisting of at least a distal end, a proximal end, and a middle section between the distal and proximal ends. The contacts of the present invention exhibit a contact diametric true position with respect to one another in an array of less than 0.2 millimeters. The electrical contacts are created in batch form from a high conductivity sheet of spring material such as a copper alloy. At least one end of the contact is elastic and emanates from one surface of the connector housing to enable formation of a separable, low resistance and reliable electrical connection to a terminal on a mating circuit element. A second end of the contact may also be elastic, or may be designed to permanently mount on a terminal on a second mating circuit element using attachment means such as solder. Contacts can be made by batch stamping and forming in reel to reel processing, and may remain integral to the contact strip or sheet during all connector fabrication processes including contact stamping, contact forming, contact plating, integration into the connector housing such as by over-molding, and through all other processing until singulation of the individual contacts and the whole of the connector′ from the contact sheet, and, as needed to provide proper connector function, from one another.
