Custom cables assembly design guide

Why Use Custom Cable Design?

Steps to Design Custom Cables

1. Define the Purpose of the Cable:
• Is the cable designed for charging only, or does it need to support data transfer as well?
• Consider the main device and any peripherals (such as sensors or monitors) the cable will connect to.
2. Understand Power and Data Transfer Protocols:
   • Identify the power requirements (e.g., voltage and current).
   • Define the data transfer protocols required, such as USB, Ethernet, or proprietary communication standards.
3. Consider the Environment and Usage:
   • Is the cable for general, everyday use, or does it need to withstand heavy usage, medical environments, or harsh conditions like extreme temperatures or outdoor exposure?
   • Factor in bending and long-term durability, especially for cables that will undergo frequent movement, such as in robotics or industrial applications.
4. Select Connectors:
   • Choose from various connectors, such as Connector 1, Connector 2, or Connector 3, based on your application needs.
   • Decide whether to use brand-name connectors or equivalent ones.
5. Choose the Right Tooling Design:
   • Select the appropriate molding design based on the application field. For example, special shape molding, angle-specific molding, or structural molding designs..
6. Choose Wire Materials:
   • Decide on wire structure, AWG (American Wire Gauge), color, and the material for the wire jacket (PVC, TPE, TPU, etc.).
7. Design the Wiring Diagram:
   • Define current and voltage ratings for the cables.
   • Draw out the wiring diagram, ensuring that all components meet design specifications.
8. Specify Tolerances and BOM:
• Mark tolerance levels and include a Bill of Materials (BOM) in the datasheet.
• Determine the test methods to ensure the design meets performance criteria.
• 
9. Transform the Design into Samples:
   • Once the design is finalized, send it to the assembly factory for evaluation. Ensure that the tooling design is feasible and that assembly is possible.
10. Prototype and Testing:
    • After receiving confirmation from the factory, proceed with mold creation and sample production. The mold cycle usually takes between 7 to 14 days, and material procurement can happen simultaneously.
    • Once samples are made, perform functionality and appearance tests.
11. Finalization of Production:
• Once the samples are tested and approved, set the production schedule. The mass production phase can be tracked in real-time to ensure timely delivery.
