Magnecomp Assigned Patent

Magnecomp Corp., Murrieta, CA, has been assigned a patent (8,810,972) developed by Christopher G. Dunn, Austin, TX, for an “electrical interconnect from disk drive suspension flexure to PZT motor.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An electrical interconnect from a suspension electrical circuit to a PZT microactuator motor includes copper plated onto a first side of a stainless steel support layer and gold plated onto a second and opposite side of the stainless steel support layer, with the gold plated stainless steel surface bonded to the PZT motor surface by conductive epoxy. The stainless steel may have a via etched into it to the copper surface before the gold plating step which then plates both the stainless steel and the copper with gold, so that the conductive epoxy is in physical and electrical contact with both the gold plated stainless steel and thus in electrical contact with the copper, and also in direct physical and electrical contact with the gold plated copper.”

The patent application was filed on Dec. 10, 2013 (14/102,123).
