Introduction
Inside almost every electronic device is at least one printed circuit board (PCB) onto which the semiconductor and other components are mechanically and electrically connected by soldering. These PCBs are designed using a computer-aided design (CAD) system.{{cite web

}} To physically realize the design, the computerized design information must be transferred to a photolithographic computer-aided manufacturing (CAM) system.{{cite web

}} Since the CAD and CAM systems are generally produced by different companies, they have to agree on a CAD-to-CAM data exchange format to transfer the data. ODB++ is one such file format for performing this transfer.{{cite magazine

}} Other formats are compared and contrasted below. After the bare board is manufactured, the electronic components are placed and soldered, for example by SMT placement equipment and wave or reflow soldering.
File structure
ODB++ can handle all the specifications surrounding a PCB – i.e. not only the basic dimensions and the layout of conducting layers and drill data, but optionally also material stack up, netlist with test points, component bill of materials, component placement and fabrication data.
The data for all these different aspects is stored in a collection of separate files within a specified hierarchy of file folders.

For simplified archiving and transmission the collection is usually packed in a single archive-file that preserves the file structure, for example using tar or gzip or both.
History
Valor was founded in 1992{{cite web

}} and it released ODB in 1995. It added the ++ suffix when component names were added in 1997. The XML version was developed beginning 2000, and ended in 2008 with the donation to IPC. Valor was acquired by Mentor in 2010.
The ODB++ data format was expanded in 2020{{Cite web|author=|date=2020-05-19|title=Siemens Expands ODB Data Exchange Format|url=https://www.digitalengineering247.com/article/siemens-expands-odb-data-exchange-format|access-date=2021-06-08|website=Digital Engineering|language=en|archive-date=2021-06-08|archive-url=https://web.archive.org/web/20210608203815/https://www.digitalengineering247.com/article/siemens-expands-odb-data-exchange-format|url-status=live}} and was designed to facilitate communication between designer and manufacturer by use of a digital twin. The format was renamed the ODB++ Family and was split into three connected format uses.
- ODB++Design: Created using typical EDA software, used for design for manufacturing, fabrication, test and assembly analysis (DFx), as well as being the single carrier of design data to electronics assembly and fabrication.
- ODB++Process: A transitional format for conversion of design data into files for use at any production machine or workstation.
- ODB++Manufacturing: A format for manufacturing floor events, with communication capabilities between machines and Smart Industry 4.0 software solutions.{{Cite web|title=Siemens Expands ODB Data Exchange Format and Adds Electronics Manufacturing Information Flow To Digital Twin|url=https://www.arcweb.com/blog/siemens-expands-odb-data-exchange-format-adds-electronics-manufacturing-information-flow|access-date=2021-06-08|website=ARC Advisory Group|date=20 May 2020 |language=en|archive-date=2021-06-08|archive-url=https://web.archive.org/web/20210608203814/https://www.arcweb.com/blog/siemens-expands-odb-data-exchange-format-adds-electronics-manufacturing-information-flow|url-status=live}}
Adoption
In the late 1990s it became clear to industry participants that a second-generation data transfer format would be more efficient than prevalent Gerber format, which was a first generation format at that time. However, it was very difficult to reach a consensus over which of two candidates should be selected:
- ODB++: proven but proprietary
- IPC-2511 GenCAM: not widely used but open
In 2002, a compromise format, ODB++(X), was recommended by National Electronics Manufacturing Initiative (NEMI; an industry body, subsequently renamed International Electronics Manufacturing Initiative, iNEMI) after a two-year mediation effort between the GenCAM and ODB++ camps. Companies that supported the recommendation at the time included Cadence, Hewlett-Packard, Lucent, Easylogix, Mentor (which acquired Valor some eight years later), Nokia and Xerox. But in fact adoption to date has been minimal. As a result, and as detailed below, the industry is still divided. Late 2014 Gerber X2 was introduced which added attributes ("intelligence") to the Gerber format in a compatible way, converting Gerber to a second generation format.{{cite web|title=Gerber version 2 FAQ|url=http://www.ucamco.com/files/downloads/file/125/the_gerber_file_format_version_2_faq.pdf|access-date=3 December 2016|work=ucamco|archive-date=6 May 2016|archive-url=https://web.archive.org/web/20160506170457/https://www.ucamco.com/files/downloads/file/125/the_gerber_file_format_version_2_faq.pdf|url-status=live}}

Some companies that have adopted the ODB++ format are advocates for its use. Streamline Circuits reports that ODB++ provides much greater efficiency than the competing Gerber format, stating that "an 8-layer printed circuit board can take up to 5 hours to plan and tool using Gerber and only 1 hour when using ODB++." According to Streamline, manufacturers are adopting it to overcome the limitations of the simpler Gerber format.{{cite web

=Criticism=
==Concerns==
ODB++ is a proprietary format controlled by Valor later Mentor and now Siemens, and so, like all proprietary standards, it comes with the risk of vendor lock-in. CAD companies had some concerns about this when ODB++ was controlled by Valor, a CAM company, but these concerns were magnified when a rival CAD company, Mentor, acquired Valor. Although Mentor claims that it
"...openly supports inclusion of ODB++ and updates for other EDA tool vendors,"{{cite webit used to restrict access to the specification{{cite web| url=http://www.mentor.com/products/pcb-system-design/upload/odb-plus-plus-ds.pdf

Alternatives
Critics of the proprietary nature of ODB++ point to several more open formats as models for a future consensus format:
