2. Description of the Related Art Conventionally, at the time of designing a printed circuit board, a design rule check is performed by a designer visually checking a component arrangement position, a pattern shape, a land shape with reference to a design standard document, or a CAD system design rule check. (Hereinafter referred to as DRC), a common connection check and interval check are mainly performed.

[0003] Also, manufacturing design know-how for preventing the occurrence of quality defects in a mounting line of a factory (manufacturing) department, which is a manufacturing site, is compiled into a list of problem countermeasures, a design standard, and the like. Had been passed to.

[0004]

However, in the conventional DRC method, since the manufacturing design check is not performed by the method of construction or the regulation of the equipment, only the common graphic check is performed. There has been a problem that there are many design modifications and a large cost is incurred due to quality loss.

[0005] Further, since the manufacturing design policy differs depending on the substrate to be developed, checks that conform to the manufacturing design due to factory construction methods and equipment regulations have not been made. There was also a problem that waste such as checking occurred.

In addition, manufacturing design know-how for preventing quality defects in a mounting line at a manufacturing site in a factory (manufacturing) department is compiled into a problem countermeasure list or a design standard document, and is passed to the design department. Depending on the worker who sees and recognizes how far the manufacturing design check may be, there is variation, and the manufacturing design check by preventing quality defects that occurred at the factory is not immediately included in the design standard document, so There is a problem that the same quality defect occurs on other substrates.

In view of the above-mentioned conventional problems, the present invention makes it possible to make a database of manufacturing design know-how for preventing quality defects on a mounting line at a manufacturing site and feed it back to a design department. It is an object of the present invention to provide a printed circuit board mounting system capable of automatically checking a printed circuit board.

The design department can quickly check the manufacturing know-how in the factory (manufacturing) department without making mistakes twice in the design department. You can give feedback.

[0010] Further, the mounting quality check device includes a manufacturing design check operation screen unit, manufacturing design policy data, a manufacturing check control database unit for creating manufacturing design rules, and a check value of the manufacturing design rule. Assuming that it has a stored manufacturing check parameter database unit and a check execution module unit that verifies whether the printed circuit board mounting data converted from the CAD system satisfies the manufacturing design rule, It is possible to check the mounting quality without omission by organizing and classifying manufacturing design rules and reference values. Even if the check method is registered only once as an execution module, even if the user is not skilled in CAD at the check execution module section You can easily use the check function It is not necessary to register check values and condition values many times, and by registering a check function that is not in the DRC function of the CAD system as an execution module, it is possible to compensate for the lack of the CAD check function and reduce the check work. It is effective for

A check execution result database unit for storing the check execution result and an error graphic display function unit for retrieving the check execution result from the check execution result database unit and displaying the graphic data subject to the error on a printed circuit board mounting screen are provided. If provided, the correction location of the printed circuit board design data can be easily determined.
