Abstract
The present invention relates to a method and apparatus of fabricating electromagnetic coil vanes. The method involves photolithographically exposing high resolution, dense wire patterns in a flash coat of copper, on both sides of a ceramic vane substrate. The substrate can be pre-drilled with a through hole to connect the two copper coil patterns. Additional copper is then deposited on both high resolution patterns and in the through hole by plating until the desired thickness is obtained. A firing operation is then performed that eutectically bonds the copper to the ceramic.
