CAD and CAM systems are often produced by different companies, so, it is necessary to agree on a CAD-to-CAM data exchange format. ODB++ is such a format and arguably the closest to a global industry standard. Developed and released by Valor Computerized Systems, Ltd. in 1995, it was and still is continuously improving to meet the evolving needs of PCB designers, fabricators, and assemblers.
In 1997 together with component names the ++ suffix was added in reference to C++ and in 2000 development of an XML version started, which ended in 2008 when this new ODB++ format, called ODB++(X), was donated to the Association Connecting Electronics Industries (IPC) in an attempt to merge GenCAM (IPC-2511) and ODB++ into a new format called IPC-2581. ODB++ is the de facto standard for intelligent PCB data exchange containing all data necessary to fabricate, assemble and test in a single hierarchical file structure which makes it superior to the only format more popular: Gerber.
Some of the major benefits of ODB++ include:
The aforementioned reasons explain why ODB++ is the standard format of PCB-Investigator, which is always used internally even if the data were imported in a different format.
