IPC A 620 Revision F

IPC/WHMA-A-620F (2025) – Requirements and Acceptance for Cable, Wire and Harness Assemblies (Latest Revision)

IPC/WHMA-A-620 Revision F (published October 1, 2025) is the global industry-consensus standard and benchmark for the requirements and acceptance criteria in the manufacture of cable assemblies, wire harness assemblies, and related interconnections. Developed jointly by IPC and WHMA, it defines best practices, materials, methods, tests, and visual/mechanical acceptance criteria for producing high-quality crimped, mechanically secured, and soldered connections.

Key Scope and Features

• Covers the full range of cable and wire harness assembly processes, including preparation, crimping, soldering, ultrasonic welding, splicing, connectors, shielding, overmolding, marking, and more.
• Applies to three product classes (Class 1: general electronic products; Class 2: dedicated service; Class 3: high-performance/harsh environment) to match end-use reliability needs.
• Does not include criteria for cross-section or X-ray evaluation (see Appendix D for X-ray guidelines).
• In case of conflict, the English version takes precedence over translations.
• Notes that “cable” and “wire harness” terms are used interchangeably in this document.
• Can serve as a standalone document for purchasing and specifying products, but does not define inspection frequencies or limits on process indicators, repairs/reworks — develop these via a statistical process control plan (refer to IPC-9191).

This latest Revision F (IPC/WHMA-A-620F) incorporates the most up-to-date guidance to ensure consistent quality, reliability, and compliance in industries like aerospace, automotive, medical, defense, consumer electronics, and industrial manufacturing.

Whether you’re a manufacturer, supplier, quality inspector, or buyer requiring cable harness acceptance criteria, wire assembly standards, or IPC certification alignment, IPC/WHMA-A-620F is essential for maintaining world-class production standards.
