Abstract
Abstract A conductive gel interconnection apparatus forming either a permanent or disconnectable electrical interconnection between multiple components is disclosed. Conductive particles are dispersed within a dielectric gelatinous medium and a concentration exceeding the percolation threshold to impart conductivity to the gel. Discrete electrical components or a plurality of components located on a substrate, such as a printed circuit board, can be interconnected by positioning the components in registration with the conductive gel located in cavities within an insulative body. The conductive gel forms a coherent mass and does not adhere to the electrical components upon withdrawal.
