WHMA/IPC Releases IPC/WHMA-A-620 Rev E

The newest revision is here and ready for you!

The IPC/WHMA-A-620 Revision E, Requirements and Acceptance for Cable and Wire Harness Assemblies prescribes practices and requirements for the manufacturing of cable, wire, and harness assemblies, and describes materials, methods, tests, and acceptability criteria for producing crimped, mechanically secured, and soldered interconnections, and the related assembly activities associated with cable and harness assemblies. It is the ONLY industry-consensus standard for cable and wire harness assembly requirements and acceptance.             

Revision E showcases significant changes to the standard, at the request of the industry. The WHMA/IPC-A-620 standards development committee adopted a new chaptering system for the entire document, added new figures and updated several sections of the standard. Of significance was the alignment of soldering requirements with IPC J-STD-001, Requirements for Soldered Electrical and Electronic Assemblies. The Circular Mill Area was revised and terms and definitions in Appendix A were updated.                                                                                           

“IPC/WHMA-A-620E sets expectations between WHMA members and their customers for what is considered acceptable quality workmanship for cables and harnesses,” said David Bergman, IPC vice president of standards and technology. “The revisions requested by the industry were significant, resulting in a much-improved standard.”
