1. A method of manufacturing a printed circuit board having an overcurrent safety construction for protecting electrical components of the printed circuit board against overcurrent damage, which comprises the steps of:

  • (a) forming a metal foil pattern on the board and simultaneously forming a narrow gap in said metal foil between the position at which said pattern is to be connected to a power source and the position at which said components to be protected are to be mounted on said board;

    (b) mounting said circuit components on said board; and

    (c) dipping the printed circuit board in a reservoir of molten solder so as to form simultaneously a bridge across the gap and connections to said components in circuit mounted on the board.
