Why are cables important:
• Compliance Testing
• Band-Aids for Bad Designs
• Impedance control for high speed digital communications is critical.
• Shielding termination techniques can significantly change EMI radiation
• Modern Robotic systems require complex and Robust harnessing.
Cables are Crazy Important!

Cable Drawing Deliverables:
• BOM
• Schematic
• Annotated drawings
• Notes
Documentation your customers need to build cables inspect cables and
purchase cables.
What Do We Need
Get What You Want:
• Contract Manufacturer or In house staff. SAME OBJECTIVE
• Easily moving between vendors
• Procurement should be able source alternative parts
• Inspection should be able inspect your cables
• Procurement
• Make sure you drawings have the important information available
• If color for instance doesn’t matter you could mention Color: Any
• Inspection
• Only provided values that can be verified with available testing methods.

Who Are Your Customers
Cable Drawing Example #1
• Good cable drawing,
• Schematic
• Testing specifications
• Packaging considerations
• Better to use a spec
• Standardize

No need to add another program:
• Getting you Electrical Engineer to
own the assembly drawing.
• Incorporating the Electrical
Schematic
• Maintaining a single library for
your design
