Document Type and Number:
WIPO Patent Application WO/2012/005025
Kind Code:
A1
Abstract:
In a circuit board (20) for transmitting signals, a pulse transformer (12A) is provided in a circuit board (20) path for transmitting signals. A shield member (15) is mounted on the circuit board (20) in order to prevent noise from entering the pulse transformer (12A), said noise being generated due to a noise current that flows through a wiring pattern (16) for noise. The shield member (15) covers the surface of at least one of the pulse transfer portions (the upper surface (26) and the side surface (27)), said portions intersecting concentric circles (30) having, as a center axis, an axis (A) in the direction in which the noise current flows.
