Abstract
The invention relates to a planar coil circuit and provides an improved method for insulating a face of a planar circuit of the type typically used in a transformer, while leaving the terminals thereof exposed; and to a planar printed circuit or lead frame stamped or etched solid copper similar to printed circuits but with no base material core manufactured using this method.
