Electronic card with serpentine contacting zone

摘要

The board has electronic components connected using conductors. A contacting zone (4) is conductive and connected to the conductors. The contacting zone presents a winding trace with parts (41-44) separated by an interval whose width is less than smallest width of a contacting point (3), such that the contacting point contacts with the separated parts irrespective of an impact point of a point on the zone.
