Abstract
An electric circuit is applied to an object having a curved surface. The curved surface of the object is divided into sections, and the circuit is applied one section at a time. The circuit is formed between layers of dielectric material. The dielectric is applied by a computer-controlled device, which controls the position of a spray head and the rotation of the object, such that the spray head is held substantially perpendicular to the surface of the object at all times, and such that a controlled thickness of dielectric material can be deposited. The fine-featured circuits formed by the invention are rugged, and can be used on objects intended to be exposed to harsh environments.
