Abstract

Aspects of the invention recite wire bonding on thinned portions of a lead-frame that is configured for use in an IC package. A harder lead-frame material, improved adhesive tape, and various structural features of the lead-frame itself, in various combinations or subcombinations, facilitate the attachment of wire bonds to thinned areas of the lead-frame. This eliminates the need for supports placed directly under the bond sites, removing unwanted conductive areas on the outer surface of an IC package.
