Sandia National Laboratories has developed a precision capacitor-roll-winding technology which we believe is essential to high-reliability designs using plastic-film dielectrics. The need for this winding capability developed during the research and development phase of the perfluorocarbon-capacitor technology described earlier. It has been found during the research and development phase of this technology that a number of winding parameters are critical to the electrical performance of plastic-film capacitors. For example, controlling the looseness of the winding is critical to electrical performance. Small differences in looseness can result in orders of magnitude change in discharge life. Excessive wander of the extended aluminum foils creates a difficult electroding problem. This paper justifies the need for this precision winding technology, summarizes the features required, and describes two machine designs incorporating these features.
