Wire Harness Assembly Standards

Following IPC Wire Harness Assembly Standards offers tremendous benefits for Wire Harness Manufacturers. 

The Wire Harness Manufacturer’s Association and the IPC (Association Connecting Electronics Industries) combined forces to create the “IPC/​WHMA-A-620C Requirements and Acceptance for Cable and Wire Harness Assemblies” which is an amazing resource for Wire Harness Manufacturers

The IPC/WHMA-A-620C serves as the only industry-consensus international Wire Harness Assembly Standard for the performance and acceptance of cable and wire harness assemblies. 

As you well know, manufacturing products based on strict industry standards creates a healthy competitive advantage. 

This also ensures high quality products which in turn creates satisfied customers. 

Consequently, manufacturing Wire Harness Assemblies falls in this category. 

Especially since Wire Harness Manufacturing comes with many challenges. 

There are many moving parts (no pun intended). 

In particular, electrical components keep getting smaller and smaller. 

This invites many demands for Wire Harness Manufacturers to stay current with proper crimp tools and equipment due to decreasing sizes. 

In addition, staff training also plays a critical role. 

As a result, keeping current with Wire Harness Assembly Standards keeps a company aligned with customer expectations. 

For that reason, closely following IPC/WHMA-A-620C Wire Harness Assembly Standards serves as an absolute top priority for Wire Harness Manufacturers

IPC/WHMA-A-620C: Wire Harness Assembly Standards

Creating a wire harness assembly without following a standardized guide could lead to disaster. 

Above all, poor assembly methods creates extremely unhappy customers. 

The guiding principle of the IPC Wire Harness Assembly standardization efforts include the following: 

  • Show relationship for Design for Manufacturability and Design for the Environment 
  • Minimize time to market 
  • Contain simple language 
  • Focus on end product performance
  • Include a feedback system on use and problems for future improvement 

Most importantly, the standard creates a consistency among manufacturers and purchasers. Maintaining a consistent level of acceptability helps prevent misunderstandings between parties. 

Additionally, the IPC standard follows all procedures to qualify for ANSI approval

Above all, this book deliver priceless information for seasoned veterans as well as those brand new to creating a wire harness.

For example, manufacturers, engineers and new product developers will find information in this book invaluable.

This book covers a wealth of topics including preparation, soldered and crimp terminations, insulation, slices and much more.

The IPC/​WHMA-A-620C provides helpful information on Wire Harness Manufacturing Terms and Definitions.
