Abstract: A procelain on steel printed circuit board includes apertures whose edges are rounded. An aperture is formed by first punching or otherwise making an aperture in the uncoated steel of somewhat larger size than desired, then employing a pair of dies, each with rounded shoulders and a center region of smaller area than the aperture. When the board is placed between the dies with the center region of the latter aligned with an aperture, and pressure is applied to the dies, they engage and round the edges of the aperture.

The steel is coated with porcelain after the finished apertures are formed.
