Abstract:
1. A system for inductance testing a plurality of planar magnetic circuits, comprising: a substrate; a plurality of cores spaced and electrically isolated from one another and mounted on said substrate, wherein each one of said plurality of cores registers with a corresponding one of said plurality of planar magnetic circuits; a carnage moveable on one or more axes with respect to said plurality of planar magnetic circuits; a pair of leads, wherein said leads are mounted to said carriage; a controller, which coordinates the actions of said carriage and said leads so as to implement testing; wherein said controller selects one of said plurality of planar magnetic circuits and contacts said pair of leads with said selected planar magnetic circuit and delivers an electrical current through said selected planar magnetic circuit while the corresponding registered core enhances inductance in said selected planar magnetic circuit; wherein, after said selected planar magnetic circuit is tested, said controller positions the leads so that another planar magnetic circuit may be tested; and an inductance measuring tool.
