摘要 |
In order to reduce the costs of assembled printed circuit boards, a printed board fuse (1) has been developed, which functions with great reliability at low manufacturing costs. By coating a large area of a printed board with metal, for example, by plating, a well-defined thickness of a metal layer (9) may be achieved in which a fuse (3) has been separated. The well-defined thickness also allows well-defined geometry of the fuse cross-sectional area and fuse length to be achieved and therefore its resistance and interruption characteristics will also be very accurately defined. In case of a temperature rise, the metal layer (9) surrounding the fuse (3) will have a heat dissipating effect on the fuse, implying an essentially reduced risk of board fire. <IMAGE> |
