BANNOCKBURN, IL – The B revision of IPC/WHMA-A-620, Requirements and Acceptance for Cable and Wire Harness Assemblies, has been released.

This standard is a joint effort of IPC and the Wire Harness Manufacturer’s Association.

It includes technical updates, greater ease-of-use, and compatibility with other assembly standards. The revision addresses more than 500 documented recommendations from users throughout the industry and features 125 new or changed illustrations.

Some of the most extensive changes appear in the molding and potting section, which has been expanded for increased coverage of Class 2 and 3 requirements, including 31 new illustrations.

The document also provides new criteria for wires as small as 32 AWG, and has a section on requirements flow down, which requires companies to have their subcontractors use the standard to ensure all hardware is manufactured to the same guidelines.

In addition, the revised document allows users to more easily reference and apply criteria from multiple standards, thanks to greater compatibility with J-STD-001E, Requirements for Soldered Electrical and Electronic Assemblies and IPC-A-610E, Acceptability of Electronic Assemblies.

The revision includes the addition of UL, SAE and IEC pull-force tables. The document is 400 pages and features 682 full-color illustrations.
