What Is IPC-WHMA-A-620?

The IPC-WHMA-A-620, Requirements and Acceptance for Cable/Wire Harness Assemblies is a joint project of IPC (Institute of Printed Circuits) and WHMA (Wire Harness Manufacturers Association). Originally released in 2002, IPC/WHMA-A-620 has become the industry standard against for quality.

What SHINE’s IPC-WHMA-A-620 Certification Means for You

Today, IPC/WHMA-A-620 is the most important process, materials, and inspections standard for the cable assembly and wire harness industry.

IPC-WHMA-A-620 Criteria and Classes

IPC-WHMA-A-620 describes acceptability criteria for crimped, mechanically secured, and soldered interconnections and the corresponding lacing/restraining criteria associated with cable and harness assemblies. Three classes of products are defined and each includes criteria for Target, Acceptable, Process Indicator and Defect conditions.

IPC-WHMA-A-620 Class 1

IPC/WHMA-A-620 Class 1 products are suitable for applications where the major requirement is a function of the complete assembly. Examples include general electronic products such as consumer devices.

IPC-WHMA-A-620 Class 2

IPC/WHMA-A-620 Class 2 products require continued performance and extended life. Uninterrupted service is desired, but not critical. Class 2 products include communications equipment and other dedicated-service electronic products.

IPC-WHMA-A-620 Class 3

IPC/WHMA-A-620 Class 3 products meet all of the following criteria

  • continued performance or performance-on-demand is critical,
  • equipment downtime cannot be tolerated,
  • end-use environment may be uncommonly harsh, and
  • equipment must function when required.
