ABSTRACT:
A flexible circuit, sufficiently rigid for easy handling, is inserted once into the window of an integrally formed core member for a magnetic or ferrite head assembly. This flexible circuit contains a pattern of several parallel conductors. When the flexible circuit is bent around the core member, the ends of the parallel conductors come together. When respective ends are soldered together, a continuous multi-turn winding is created. Only one insertion is required, the flexible circuit is less prone to breakage, the electrical characteristics are repeatable, and the turns are inherently shielded and insulated from each other. Most importantly, the flexible circuit is easily adapted to an automated assembly line.
