The need for an independent format that covers the wide range of printed circuit board (PCB) design and assembly requirements has been recognized for many years. IPC-2581 is an independently developed and maintained format for manufacturing output. This format is supported in both Allegro PCB Designer and OrCAD PCB Designer.

IPC-2581 specifies the XML schema that represents the intelligent data file format used to describe PCB and PCB assembly products with details sufficient for tooling, manufacturing, assembly, and inspection requirements. This format may be used for transmitting information between a PCB designer and a manufacturing or assembly facility. The data is most useful when the manufacturing cycle includes computer-aided processes and numerical control machines.

Cadence is a founding member of the recently formed consortium for supply-chain adoption of IPC-2581. The consortium’s goal is “to accelerate the adoption of IPC-2581 as an open, neutrally maintained global standard to encourage innovation, improve efficiency, and reduce costs.”

Cadence statement in support of IPC-2581
Cadence believes it is in the industry’s best interest that an open, public, neutrally maintained standard be adopted by all segments of the PCB design, fabrication, assembly, and test supply-chain. Cadence commits to developing and maintaining IPC-2581 import and export from its Allegro® and OrCAD PCB Designer software and staying current with the latest approved and published IPC-2581 specifications. Cadence additionally commits to collaborating with all consortia members to ensure that IPC-2581 data produced by Allegro and OrCAD can be accurately and smoothly consumed by their technologies, methodologies, and processes.
