Significant technical updates, greater ease-of-use and compatibility with other key assembly standards are among the many changes users will find in the newly released B revision of IPC/WHMA-A-620 ‘Requirements and Acceptance for Cable and Wire Harness Assemblies’. This industry standard is a joint effort of IPC and the Wire Harness Manufacturer’s Association (WHMA).
The revision addresses more than 500 documented comments and recommendations from users throughout the industry and features 125 new or changed illustrations.
Some of the most extensive changes appear in the moulding 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 the widely used J-STD-001E ‘Requirements for Soldered Electrical and Electronic Assemblies and IPC-A-610E, Acceptability of Electronic Assemblies’.
Users with varying reliability requirements and markets in different regions will also have greater ease-of-use with the addition of UL, SAE and IEC pull-force tables.
