IPC WHMA-A-620 - Acceptability of Cable and Wire Harness Assemblies

IPC 620 CIT training at Electronics Yorkshire

Improve the quality of your cable and wire harnesses, reducing errors and costs, with IPC WHMA-A-620 certification.

Most electrical/electronic assemblies and products get connected, one way or another, to something else via a cable or wire harness of some sort, or include internal connections and cabling. Faulty cables can be amongst the hardest items to diagnose, especially as many cable harnesses are used in adverse environments such as automotive or aerospace.

You don’t want your products to fail due to a fault in a wire harness, and your customers certainly don’t want to be let down.

Companies have seen significant improvements in quality through implementing the IPC cable harness programme, as staff are much better able to identify and solve problems when they work to well-defined criteria of what is acceptable and unacceptable.

Applying the IPC WHMA-A-620 Standard to your business will help reduce problems and therefore save you time and money. IPC WHMA-A-620 certification also demonstrates a commitment to customer requirements and can help achieve ISO certification or other quality assurance initiatives.

Who should attend IPC WHMA-A-620 training?

This standard is aimed at anyone responsible for manufacturing cable and wire harnesses, for making products and assemblies that include wires, cables and connectors, or for anyone assessing cables in goods in, such as:

  • assembly operators
  • quality controllers
  • inspection personnel
  • anyone responsible for the quality and reliability of cable and wire assemblies

IPC WHMA-A-620 for trainers or staff

There are two levels of IPC WHMA-A-620 training.

  • To have your team able to apply the standard you need the Application Specialist (or CIS) level.
  • To take responsibility for your own training at least one of your team must gain the Certified IPC Trainer (or CIT) level to train and certify the rest of their colleagues. Any company which has a large number of staff who will benefit from IPC WHMA-A-620 knowledge and certification may find it more beneficial to train and maintain their own employees.

Electronics Yorkshire has Master IPC Trainers delivering CIS and CIT certification across all five practical and classroom-based IPC programmes.

IPC WHMA WHMA-A-620 course overview

IPC WHMA-A-620 is the leading industry standard for cable and wire harness fabrication and installation. The course enables staff to understand procedures for fault finding, rectification, methods of soldering and quality of finished product on cable and wire harness assemblies.

The IPC WHMA-A-620 standard describes the acceptability criteria for crimped, mechanically secured and soldered interconnections and the corresponding lacing/restraining criteria associated with cable and harness assemblies.

IPC WHMA-A-620 covers three classes of quality assurance:

Class 1 General electronic products - such as cameras, audio/video and domestic appliances. The lifetime of these products is limited, and a failure is not critical.
Class 2 Dedicated service electronic products - such as printers, copiers, computers and general production equipment. The lifetime of the products is longer than class 1, the amount of usage is higher, and an uninterrupted service is desirable.
Class 3 High reliability/critical products - such as military, aerospace and medical. Not only is the product lifetime extended but the products must function without interruption and downtime is not an acceptable option.


IPC WHMA-A-620 is a modular programme. Apart from mandatory modules your staff may only need the elements relevant to your company; however both IPC and Electronics Yorkshire strongly recommend that all modules are taken. For Certified Trainers all modules are mandatory; CIS courses listed in the Training Calendar include all modules.
