Equipping the PCB Design and Supply Chain with 21st Century Data

The consortium was created in June and includes the following founding members from across the PCB design/supply chain:

  • OEMs: Harris, Ericsson, Fujitsu, nVidia.
  • EMS/ODM: Sanmina-SCI.
  • Software tools: ADIVA, Cadence, Downstream Technologies, Zuken.
  • Media: UP Media Group.

The consortium is open to any PCB design/supply chain company that is prepared to adopt the consortia goals/objectives and commit to a roadmap for IPC2581 adoption: a) publicly state that the company is a supporter of IPC2581, and b) actively support IPC2581 by either producing or consuming IPC2581 in the next 12 to 16 months.

Further, systems companies are asked to require suppliers to produce/consume IPC-2581 data within the next 12 months. EDA design tool companies are asked to output IPC-2581 from board designs. DfM verification companies must export IPC-2581, and fabricators, assemblers and test companies must import and consume IPC-2581.

Why is Cadence Design Systems involved, and to what degree? 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 develop and maintain IPC-2581 import and export from its Allegro PCB design software and stay current with the latest approved and published IPC-2581 specification. Cadence additionally commits to collaborating with all consortium members to ensure that Allegro-derived IPC-2581 data can be accurately and smoothly consumed by their technology(ies), methodology(ies) and process(es).

Whither ODB++? Before being acquired by Mentor Graphics, Valor Systems was in some ways a major contributor to IPC-2581. Indeed, Valor donated its ODB++X format, which was merged with IPC’s GenCAM to form the foundation of IPC-2581. With ODB++/ODB++X no longer in the open “pseudo standard” domain, the consortium feels compelled to ensure that an open, unbiased “living” standard is maintained, adopted and promoted across the global supply-chain.

Eastern-US: China’s New Competitor?

Parity emerges among EMS Factories from Asia, Mexico and the US.

For the first time in years we see parity in the Eastern US among EMS factories from Asia, Mexico and the US. This EMS market condition will permit American OEMs (the EMS industry refers to OEMs as customers) to have more EMS pathways to choose from. Now more than ever, such EMS assignments will require deeper investigation relating to the OEMs’ evaluation of manufacturing strategies.
