An electronic circuit board (6) has a surface with at least one conducting island (7), and the surface is arranged proximate to a first insulating material (3) having a number of holes (8) which correspond to at least some of the conducting islands (7) and through which the conducting islands (7) may be reached. At an end thereof facing the surface, each hole (8) has an area which is larger than the area of the corresponding conducting island (7). A conducting area (10; 14, 15, 16, 17) adapted to carry off an electrostatic discharge (ESD) is located on the surface proximate to the conducting islands (7) and within the area of the holes (8), and elements (9; 19) of a second insulating material are provided in the holes (8). Thus the electronic circuit board can withstand electrostatic discharges without the circuitry of the board being damaged.

Une carte de circuit électronique (6) présente une surface dotée d'au moins un îlot conducteur (7) et située à proximité d'un premier matériau isolant (3) possédant un certain nombre d'orifices (8) qui coïncident avec au moins certains des îlots conducteurs (7) et par lesquels les îlots conducteurs (7) peuvent être atteints. A une extrémité faisant face à ladite surface, chaque orifice (8) possède une taille plus importante que celle du ou des îlots conducteurs (7) correspondants. Une zone conductrice (10, 14, 15, 16, 17) conçue pour absorber une décharge électrostatique est située sur la surface proche des îlots conducteurs (7) et dans la zone des orifices (8), des éléments (9, 19) constitués d'un deuxième matériau isolant étant prévus dans les orifices (8). Ainsi, la carte de circuit électronique peut résister aux décharges électrostatiques sans que les circuits de la carte soient endommagés.
