Abstract
A method of making an electrical contact comprised of at least one, and preferably several, conical projections, is provided. The individual conical projections are comprised of an ablative material, and at least some of the conical projections include a surface which is substantially comprised of material in a thickness capable of making ohmic contact, either by wiping with an intermeshing like structure or by contacting a substantially flat contact pad. An interconnection, in this invention, is the combination of at least one contact having individual conical projections and another contact, optionally having individual conical projections. The conical projections are formed by laser. The conical projections are optionally formed on the head of a contact pin.
