Abstract
An electronic device which includes a circuit sheet having a conductive path thereon. An adhesive is deposited on the conductive path, the adhesive including a nonconductive base incorporating randomly spaced conductive particles. A circuit component is forced through the adhesive, the conductive path and the circuit sheet carrying a portion of the adhesive therewith between the circuit component and the conductive path. The carried portion of the adhesive is compressed for establishing contact between the conductive particles and thereby conductivity between the circuit component and the conductive path leaving the adhesive other than that portion in a nonconductive state.
