ODB++ is a comprehensive PCB manufacturing data format developed by Mentor (now Siemens) that contains all information needed for fabrication and assembly in a single structured package. Unlike Gerber (separate files for each layer), ODB++ includes layer data, drill files, netlist, component placement, design rules, and metadata. ODB++ enables automated DFM checks, intelligent panelization, and assembly programming. It's the native format for some CAM systems. IPC-2581 is a similar open-standard alternative.
