Abstract
A method for producing printed wiring board (PWB) fabrication drawings obtains (20) design information for existing PWB fabrication requirements. If a new PWB design is needed PWB fabrication files are produced (18). Next project file information is obtained (24), if a drawing change is necessary. New project file information including drill hole information (30), custom notes (32) and placement and size of drawing symbols (34) are generated. This new project information is transferred (38) to a program for production of the PWB fabrication drawings.
Claims28
A method for producing PWB fabrication drawings comprising the steps of:
- determining whether a PWB fabrication requirements, requested by a user, are new or existing;
- obtaining design information for the PWB fabrication requirements, if the PWB fabrication requirements are existing;
- producing PWB fabrication files, if the PWB fabrication requirements are new;
- determining whether a PWB fabrication drawing changes is necessary;
- obtaining project file information, if a drawing change is necessary;
- generating new project file information;
- updating a drill hole table with changes made to a drill hole of a PWB by the user;
- extracting hole data from the drill hole table;
- reading parameters of a drill hole from input from the user;
- comparing the parameters of the drill hole with the hole data from the drill hole table;
- and
- transferring the new project file information including the updated drill hole table for production of the PWB fabrication drawings.
