Anisotropic elastomeric interconnecting system

An electronic assembly comprising alternating component layers and connecting layers, said component layers being rigid structures having at least one planar face with electrical contacts formed thereon and said connecting layers being anisotropic elastomeric conductors positioned between opposed electrical contacts on adjacent component layers, wherein said anisotropic elastomeric conductors are formed by a method comprising:

• forming a stack of first and second sheets so that at least one second sheet lies between adjacent first sheets, wherein said first sheets are metal sheets, each metal sheet forming a plurality of electrical conductive elements, said electrically conductive elements running in one direction only, and said second sheets are composed of electrically insulating material;
• introducing a curable elastomeric resin to the stack;
• curing the elastomeric resin to form a solid matrix having the electrically conductive elements electrically isolated from one another and extending from one side of the block to the opposide side;
• and
• slicing the matrix in a direction transverse to the direction of the electrically conductive elements to yield said anisotropic elastomeric conductors having the elements extending thereacross.
