A brief overview of how USB cables are produced:
Wire drawing: Copper wire is drawn from copper rods through a series of dies to obtain the desired diameter.
Stranding: The copper wire is then stranded into groups of 2, 3, 4, or 5 conductors, depending on the type of USB cable being produced.
Insulation: Each conductor is insulated with a thin layer of plastic or foam material to prevent short circuits and interference between wires.
Shielding: A braided shield made of copper or aluminum is woven around the insulated conductors to provide additional protection against interference.
Jacketing: The entire cable is then sheathed in an outer jacket made of PVC or other materials to protect the internal components and provide structural support.
Connector attachment: The connectors are attached to each end of the cable using soldering or crimping techniques.
Testing: The finished USB cables are tested to ensure they meet the required specifications for signal quality and transmission speed.
