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