Abstract
Magnetic circuit elements, e.g. for inclusion on circuit boards including one or more windings about a toroidal core are produced by joinder of mating sheets, one or both recessed to hold the core, and each containing partial windings. Joinder is by use of an anisotropically conducting adhesive layer. The layer is applied as an uncured thermosetting adhesive containing spherical conducting particles of such size and distribution as to statistically result in electrical completion of windings while avoiding turn-to-turn shorting.
