Abstract: In the present method for manufacturing a magnetic write head a focused ion beam (FIB) tool is utilized to mill the side edges of a P2 pole, in order to provide a narrowed track width. Prior to milling, a thin film layer of material is deposited upon the P2 pole tip. The milling boxes of the FIB tool are properly aligned upon the layer with reference to the location of the P2 pole tip. Milling of the lateral edges of the P2 pole tip is then conducted to the appropriate depth, and the layer of material is removed. The resulting P2 pole tip has sharp lateral edges, rather than the rounded edges that are produced in prior art FIB processing methods that do not utilize the thin film layer. In a preferred implementation, the FIB tool is utilized first to deposit the thin film layer and thereafter to perform the milling operation.

Abstract: A process of manufacturing printed circuit boards which is useful in the formation of printed circuit boards containing both areas of thick conductive traces and areas of fine resolution conductors in a single conductive layer, and printed circuit boards formed from such a process. A conductive core is first fabricated containing areas of thick conductors on a relatively thin conductive base. The conductive core is then bonded to a sublayer such as “prepreg” with the thick conductive areas adjacent to the sublayer in order to form a relatively flat laminate. Proper bonding typically requires the use of high resin “prepreg” sublayer. In the alternative, an additional inner layer of pure resin cab be inserted between the conductive core and the insulating sublayer prior to bonding. After bonding, the conductive surface of the laminate is formed into printed conductor traces by methods known in the art.

Abstract: A method for depositing a thermal interface onto a heat sink including the selection of a highly thixotropic compound formed into a bulk form so as to present a tip which is melted upon contact with a preheated heat sink. The tip cross section preferably corresponds to the cross section of the heat sink. Upon depressing a tip of the compound against the heat sink a resulting vacuum therebetween cooperates with the ambient air pressure to preclude migration of the melted compound beyond the exterior of the tip such that the compound is deposited on the heat sink in the desired cross section form. Upon displacement of the tip from the heat sink, the ambient air pressure precludes subsequent migration of the compound onto the heat sink precluding a build up of the deposited material thereon. The component may then be subsequently pressed against the subsequent heat sink without a deformation of the compound tip precluding a subsequent deposit.
