[Prior Art]

 Conventionally, a CAD system for designing a printed wiring board using a computer has been widely used. In these CADs, after the design is completed, the photographic original plate drawing information and the drilling data for etching the printed wiring for manufacturing the printed circuit board are used as the data for the automatic assembly machine (for the automatic insertion and the automatic mounter) of the parts, and the placement of the parts. The target can be output as CAM information. However, in addition to the placement coordinates as information for the automatic assembly machine, the shape, insertion depth, assembly model selection data, etc., as individual component parameters, and the component placement seat based on the coordinate system of the automatic assembly machine in addition to the CAD coordinate system. Since a mark is required, an operation of adding or associating these assembling information to the output component information is required for each CAD design.

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a means 1 for providing mounting information, arrangement information, and assembling information in a parts library data, and parts mounted on a printed circuit board by using the parts library. From means 2 for creating CAM information for assembling parts by classifying the categorized into an automatic assembly machine target and an automatic assembly machine non-target, and editing information of the drawing generated by creating a manufacturing drawing of the printed board, By the means 3 for taking out the arrangement state of the board and the parts coordinates for the automatic assembly machine, and the above-mentioned three means, the electronic parts information mounted on the printed board expressed in the manufacturing drawing is taken out and mounted on the information. A procedure to add parts that cannot be expressed in the design process, such as screws, to output purchase / arrangement information for all parts as a parts summary drawing and to create parts arrangement information. A 4, and means 5 for creating a set elevational CAM information of the designated board in the board created as divided board.

[0005]

[Action]

 By using the means 1 in common in the printed circuit board mounting CAD / CAM device that automatically generates the arrangement information and the CAM information for assembly from the printed circuit board mounting design process, each design by CAD described in the conventional technique is performed. It does not require an operation of adding or associating assembly information to the component information output to, and supplies data to a process that requires arrangement information and assembly information, and realizes means 2. The means 2 can omit the operation of classifying the parts corresponding to the automatic assembly machine from the output part information. The means 3 automatically converts the coordinates of the parts into a coordinate system corresponding to the automatic assembling machine without being aware of the state of the board. The means 4 facilitates automation of arrangement work from the production of the printed circuit board to the work of assembling the parts on the printed circuit board. By means of means 5, when it is necessary to assemble only the specified board in the split board, it is easy to create the CAM information for the parts assembly and to automate the arrangement work of the assembly work.
