Processes and Techniques for Fabrication of Magnetic Plated Wire

摘要

The report details a facility for the fabrication of quality permalloy plated wires for computer memory applications. A description of the sequence of steps for a continuous plating system is included. Related parameters pertinent to production of reproducible uniform films and reduction of mechanical stresses are discussed; e.g. both composition, thickness, substrate surface, memory element, analytical techniques, electrolytic cleaning, and electropolishing. The fabrication of instrumentation necessary for measurement of switching time is described briefly. (Author)
