Abstract
An electrical interconnection medium is made as a composite of electrically conducting, magnetic particles in a nonconductive matrix material. Particles are magnetically aligned into a network which extends in at least two dimensions as, e.g., in a sheet or layer medium. A layer medium may further include additional, larger conductive particles which may be magnetically aligned into columns extending the thickness of the medium; typically, in this case, the medium serves as an anisotropically conductive medium in the direction of the columns, with slight in-plane conductivity imparted by the network aiding the dissipation of electrostatic charge.
