Printed circuit board and method for reducing radio frequency interference emissions from conductive traces on a printed circuit board

摘要

A printed circuit board includes a first helical conductive trace and a second helical conductive trace. The first helical conductive trace extends generally along a longitudinal axis of a layer of the printed circuit board. The first helical conductive trace is provided successively: along a first surface, from the first surface through the layer to a second surface, along the second surface, and from the second surface through the layer to the first surface. The second helical conductive trace extends generally along the longitudinal axis of the layer of the printed circuit board. The second helical conductive trace is provided successively: along the second surface, from the second surface through the layer to the first surface, along the first surface, and from the first surface through the layer to the second surface. A method is also provided.
