IPC-2581 (also known as DPMX - Digital Product Model Exchange) provides a unified XML-based data format for exchanging complete PCB design and manufacturing information. It consolidates artwork, drill data, stackup, netlist, BOM, pick-and-place, and assembly instructions into a single intelligent file - replacing the traditional multi-file Gerber approach. Benefits include reduced data errors, bidirectional DFM communication, and support for Industry 4.0 automation. While Gerber remains dominant, IPC-2581 adoption is growing. Ask your fabricator if they accept IPC-2581 files.
