An electronic coil wound around a magnetic core is formed by coating the core (1) with a conductive material (2) and a photosensitive material (4), creating a pattern in the photosensitive material to form a mask by exposing the photosensitive material to a collimated light source (5) while rotating the core, etching the conductive material, and removing the mask. The resulting photo-etched electronic coil can be reproduced in any number and yet has totally uniform coils. |
