Abstract
The present invention relates to a method of fabricating electromagnetic coil vanes. The method utilizes laser machining to provide high resolution, dense coil wire patterns on both sides of a ceramic vane substrate. A firing operation is first performed that eutectically bonds the copper to the ceramic. Laser machining is then used to produce a coil pattern in the copper. The substrate is drilled to provide a through hole which, when filled or partially filled with a conducting material, forms an electrical connection between the two coil patterns.
