DEVICE FOR SUPPORTING DESIGN COMPONENT ARRANGEMENT ON PRINTED BOARD

PROBLEM TO BE SOLVED: To provide a device for supporting component arrangement designing which can verify the possibility of the arrangement and wiring of all components on a printed board, before the component arrangement is designed. SOLUTION: The design support device which decides whether components can be arranged and wired on a printed board, comprises a component occupation area calculating means 61 which calculates the rate of the total fitting area of the components to the component arrangement area of the board, a component occupation area upper-limit value setting means 62 which sets the upper-limit values of the rate by the kinds of boards, and a decision means 63, which decides whether the components can be arranged and wired on the board by comparing the rate calculated by the component occupation area calculating means with the upper-limit values of the rate set by the component occupation area upper-limit value setting means. It can be decided whether all the components can be arranged and wired on the board, only by inputting data on the component arrangement area of the board to be used, the total fitting area of the components, and the kind of the board.
