Abstract: A cleaning apparatus for cleaning sensitive components such as those used in the disk drive and semi-conductor industries. The cleaning apparatus of the present invention includes of an adhesive tip mounted on a handle. The adhesive tip may be fixedly or rotatably mounted on the handle, and is further comprised of an adhesive film which may be wrapped about the handle or formed over a more compliant or more resilient surface. The adhesive film is preferably a low residue, low out gassing material which may easily remove particles from the surface of precision components without further contaminating the component.

Abstract: An etched, lubricated swage ball for use in swaging a head gimbal assembly to an actuator arm in a magnetic disk drive, and a method for making the same. The present invention discloses a lubricating system for swage balls used in a disk drive system which is free from transferrable aluminum oxide, other hard materials or excess solid lubricant which could be deposited on the clean disk surface during operation. The swage balls are first pretreated by cleaning and then etching to remove residual alumina from the surface of the swage balls. The cleaned, etched swage balls are then lubricated in a fluorocarbon lubricating system, thereby producing an etched, lubricated swage ball which is cleaner than that found in the prior art.
