Abstract

PURPOSE:To prevent the simultaneous mounting of circuit parts to be mounted selectively and prevent the occurrence of nonconformity caused thereby, in a printed wiring board which is designed so that the function may be changed by the change of the circuit parts mounted. CONSTITUTION:In a common printed wiring board 4, where the function changes between the mounting of a circuit part A and the mounting of a circuit part B, the circuit part A and the circuit part B to be mounted selectively are laid out so that one part each of mounting positions may overlap each other, and these are arranged so that the circuit part A and the circuit part b may not be mounted at the same time.

The mounting positions of the circuit components A and B forming a and 2b are shown. As shown in the drawing, the mounting positions of the two types of circuit components A and B that are selectively mounted are laid out so as to overlap each other. Therefore, only one of the circuit components A and B is mounted.
