Abstract:
A method for making a circuit assembly which includes at least one magnetic device comprising the steps of:a) providing first and second parts of a magnetic body and a substrate having first and second major surfaces, the substrate including an aperture therethrough and a conductive coil extending peripherally around the aperture; b) bonding the first part of the magnetic body to the first major surface of the substrate with adhesive material so that the first part overlies the aperture and a portion of the first part is exposed through the aperture; c) applying adhesive material to the portion of the first part exposed through the aperture; d) pressing the second part of the magnetic body through the aperture into contact with the adhesive of the first part and, under pressure, rotating the second part in relation to the first part in a reciprocating manner to spread the adhesive into a thin, uniform film; and e) curing the adhesive without clamping to bond together the first and second parts.
