PURPOSE:To provide a connecting method of circuit board so as not to exert the influence of mutual circuits when plural kinds of circuits having different properties exist the same printed wiring board (circuit board). CONSTITUTION:When the circuits having different properties, for instance, a power supply circuit 2 and a logical circuit 3 exist in a printed wiring board 1 as a circuit board, respective circuits are connected by a separating means such as a phase 6 which can be free inserted and demounted so that connection between the power supply circuit 2 and the logic circuit 3 can be separated from each other. Since the circuits existing in the circuit board are accessible from outside, a test of the circuit can be simply and easily performed, besides the damage to the other circuit due to a partial failure of the circuit board can be prevented from occurring. |
