IPC WHMA A-620: Requirements and Acceptance for Cable and Wire Harness Assemblies

IPC/WHMA-A-620 gives your team a clear, industry-recognised framework for tackling the unique challenges of cable and wire harness assembly, helping ensure every build meets globally accepted quality standards while protecting your reputation and revenue.

Whether you’re dealing with crimping issues in demanding environments, inconsistencies in inspection and testing, or increased scrutiny during customer and quality audits, IPC/WHMA-A-620 training equips your team with the skills and confidence to produce reliable, compliant, high-quality harnesses, every time.

The IPC WHMA A-620 training course and certification has become the international acceptability standard.  Electrical and electronic products have multiple connection points and related assembly activities. The IPC WHMA A-620 course is an inspection course designed to help identify what is considered acceptable quality workmanship during the assembly of the product. This training complements the IPC/WHMA A610, and will give delegates the knowledge to inspect with confidence.

While delegates should have knowledge of industry language and a basic understanding of cable manufacture, wire harnessing and soldering, there are no specific prerequisites.

This course covers the requirements and associated acceptance across multiple product classes.

Crucial for operators involved in the manufacture of cable and wiring harness assemblies, this is a must have for anyone involved with assembly or inspection of cable and wire harness assemblies.

What does it cover?

Any team or person who work within an electronics manufacturing industry team would benefit from this standard and training.

Focusing on high-performance industries such as motorsport, aerospace and defence, all roles involved in the build, test or inspection of cable and wire harnesses should have a thorough understanding of the acceptance criteria for all three classes of product:

While aerospace, defence and motorsport electronics manufacturers usually work to Class 3, the training and its standard covers all three classes – Class1, Class 2 and Class 3.

(We discuss the different class levels in our blog – Electronics Manufacturing – mastering soldering basics)

In particular, the IPC WHMA A-620 course looks at all aspects of cable and wiring harness assembly, including inspection criteria including:

Crimp Termination and Insulation Displacement Connections

Soldered Terminations and High Voltage Applications

Connector Assembly, Over-Moulding and Potting

Ultrasonic Welding and Splices

Markings, Labels and Final Assembly

Co-Axial and
Bi-Axial Assemblies

Shielding and Protective Coverings

The IPC WHMA A-620 certification usually takes 3 days and is valid for 2 years. You can recertify within 3 months before expiry but if your certificate expires, you’ll need to take the full course again.

The optional practical element takes an additional day and is also valid for 2 years.
