ABOUT THE COURSE

The Evolution of IPC’s Cable & Wire Harness Documents: IPC-D-620, IPC/WHMA-A-620 and IPC-HDBK-620

Often the most overlooked, ignored, and “taken for granted” component in a design, the high-quality cables and wiring harnesses, are essential to the performance and reliability of any electrical / electronic system.

Cables and wiring harnesses are equivalent to the human circulatory and nervous system.  They deliver energy, transmit command and control instructions, and collect and distribute sensory data describing not only the environment external to the system, but the health and status of the system itself.

This presentation will be a detailed, but often light-hearted and realistic, discussion on how the IPC’s cable and harness assembly documents were created – from the submission of comments and technical content covering acceptance requirements for cable and wire harness assemblies to be included in the IPC-A-610 “Acceptability of Electronic Assemblies” document; into the IPC/WHMA-A-620 “Requirements and Acceptance for Cable and Wire Harness Assemblies” document; the Space Addendum IPC/WHMA-A-620x-S – Space Applications Electronic Hardware Addendum to IPC/WHMA-A-620”; and then evolved to include companion documents covering design IPC-D-620 “Design and Critical Process Requirements for Cable and Wiring Harnesses”, the handbook IPC-HDBK-620 “Handbook And Guide To IPC-D-620 and IPC/WHMA-A-620”, and separate design and acceptance documents for optical fiber, optical cable, and hybrid wiring harness assemblies.

This course will also include:

• How can the documents be used – and what does the acceptance code mean?
• Why are there separate design, acceptance, and handbooks – and how they work together?
• When will there be new revisions?
• What does a handbook do / not do?
• “Hot” topics that are included in the documents
