Cable and Wiring Standard Nears Completion

A new revision of the IPC and Wire Harness Manufacturer’s Association (WHMA)  standard for cabling and wire harnesses is drawing close to completion, with publication expected in October, if not sooner.

IPC/WHMA-A-620B, Requirements and Acceptance for Cable and Wire Harness Assemblies, got a fair amount of feedback during its public comment phase, underscoring the interest level in this technology. Altogether the joint IPC and WHMA working group has resolved more than 500 documented recommendations for this revision.

Comments from the first ballot have been addressed, so the standard is now in second ballot for final approval.

The document has a significant number of improvements.  It will have more than 100 new photographs, and the section on molding and potting materials has a far larger list of criteria. And those are just a few of the changes.

“There have been some major enhancements in nearly every chapter, with updated and expanded criteria,” said Jack Crawford, IPC’s Director Certification and Assembly Technology.

To get notification when the standard is released, please e-mail KimSterling@ipc.org.

    Is the standard including cable connector, which is wire welded to connector pins?

    The IPC/WHMA-A-620B does not have criteria for welding of wires. It’s only for crimp and solder.
