IPC HDBK-620:2018

This Handbook is a companion reference to IPC-D-620 Design and Critical Process Requirements for Cable and Wiring Harnesses and IPC/WHMA-A-620 Requirements and Acceptance for Cable and Wire Harness Assemblies and is intended to provide supporting information, guidance, and technical insight into the design and acceptance requirements
for cable and wire harness assemblies.
The intent of this Handbook is to capture how and why information and provide additional technical rationale for the specification limits, acceptance criteria, as well as how those specifications and criteria interrelate. In addition, other supporting information is provided to give a broader understanding of the process considerations needed for the design and production of acceptable hardware.
The target user of this Handbook is a process or manufacturing engineer.
Reference materials listed in this text are among those considered as required reading. The User is encouraged to obtain all relevant referenced materials as this document cannot (nor can any single document) cover every material, process, environment, performance, or safety aspect that affect a given design.
This handbook addresses a wide range of technologies and processes used in cable and wiring harness assemblies, including optical fiber technology, adhesives and polymerics, torque, test, etc. Reference materials listed in this text are recommended for reading to obtain a complete understanding of the topics presented. The User is encouraged to obtain all relevant referenced materials as this document cannot (nor can any single document) cover every material, process,
environment, performance, or safety aspect that affect a given design.
It is not enough to understand the properties of the various components, materials and processes; the user should understand what is to be achieved by the set of selected components, materials, and processes within the end use environment and how to verify that the desired results have been realized.
This document is intended to be used as a reference only. It is the responsibility of the user to determine the suitability of the cable and/or wire harness assembly design as a functional system in the intended end use application.
