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.”
