International Classification:

B21D 37/16

US Classification:

723421, 7234294

Abstract:

Apparatus and method for simultaneously adjusting the gram load and radius geometry height of a head suspension by scanning a spring region of the head suspension with a laser beam. The incremental height difference between left and right legs of a spring region of the suspension may also be concurrently corrected. Apparatus and method for measuring the radius geometry height are provided by two or more non-contacting optical probes. A nitrogen atmosphere may be maintained in the region scanned.

Abstract:

A system for electroplating a web of conductive material with a source material comprises a transport mechanism, an electrical contact, a plating bath, and at least one nozzle. The transport mechanism transports the web through the system. The electrical contact electrically engages the web to cause current to flow into the web. The plating bath contains a volume of an electrically conductive liquid contain ions of the source material. The nozzle is configured to flow a low electrical conductivity fluid onto the web. A portion of the web is immersed in the electrically conductive liquid. The current flowing in the web causes the ions of the source material in the electrically conductive liquid to attach to a surface of the portion of the web.
