The ODB++ data format for PCB designs

摘要

Once a circuit design is complete and the PCB has been laid out, the complex process of transferring all the design data to manufacturing begins. The information communicates not only the physical positions of components, traces, and layers, but also the intent. On top of this is manufacturing data: where to drill, what to mask, and how to apply the board stencil. For decades this data exchange has required a lot of different files, each containing a part of the final picture, somewhat like a jigsaw puzzle.
