Abstract
An anisotropic conductive compound includes an electrically conducting material suspended in a binder. The electrically conducting material includes nickel coated particles having a coating of silver or gold over the nickel coat and/or gold or silver coated nickel particles. In one embodiment, the binder is formed from the reaction product of a catalyst and a compound comprising an aromatic epoxy resin, a dimer fatty acid diglycidyl ester and oxirane. In another embodiment, the binder is formed from the reaction product of a novalac resin, a catalyst and either a heat polymerized aromatic epoxy resin or a phenoxy modified epoxy novalac resin.
