1. A method for manufacturing a printed board fuse to protect a printed board against overcurrents, comprising the step of depositing a heat dissipating metal layer having a substantially uniform thickness on a first area of the printed board and forming at least one fuse conductor in at least one second area of the printed board upon which the heat dissipating metal layer is not deposited, the fuse conductor and the heat dissipating metal layer each having a predetermined geometry and thickness selected to provide known resistance and interruption characteristics to the fuse conductor, and the first area substantially surrounding the at least one second area.
