Abstract
A method for making a planar magnetic device is presented. The magnetic device has generally spirally-directed planar coils supported on plural substrates. The plural substrates are stacked so as to have their respective outer peripheries connected to termination pads which are laterally spaced from the termination pads of other coils, as viewed in a direction perpendicular to the planar coils. The inner termini of at least two of the coils may be interconnected by a plated via to constitute a single winding on plural planes. An exposed portion of the termination pads resides alongside vertical edges of the magnetic device and is electrically connected to a vertical plating which form pin-less terminations of the magnetic device. The magnetic device may include a beveled portion for orientation of the device in a circuit. A method of manufacturing the magnetic device is also disclosed.
