Method and apparatus for testing circuit boards
First Claim
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.

Abstract
A system and method for inductance testing a planar magnetic circuit in a board having a pair of contacts that may include a core; a pair of leads; a controller for contacting the pair of leads with the pair of contacts, registering the core with the planar magnet circuit, and delivering an electrical current through the planar magnetic circuit while the core enhances inductance in said planar magnetic circuit; and an inductance measuring tool. In another aspect, a system and method for high potential testing a planar magnetic circuit that may include providing an electrically isolated bed, loading the board on the bed, providing a pair of leads, contacting the pair of leads with the pair of contacts using a controller, delivering an electric current having a predetermined voltage between about 1,000 and about 30,000 volts through the planar magnetic circuit; and determining whether the board withstands the predetermined voltage. In another aspect, a plurality of beds may register a plurality of planar magnetic circuits.
