AN ELECTRONIC CIRCUIT BOARD, AN ARRANGEMENT COMPRISING AN INSULATING MATERIAL AND AN ELECTRONIC CIRCUIT BOARD

摘要

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 o f the holes (8), and elements (9; 19) of a second insulating material are provided in the holes (8). Thus the electronic circuit board ca n withstand electrostatic discharges without the circuitry of the board being damaged.
