Embodiment Construction
[0015] S1, removing the oxide layer on the surface of the copper wire.
[0016] Specifically, the oxide layer on the surface of the copper wire can be removed by mechanical processing, or the oxide layer on the surface of the copper wire can be removed by soaking and dissolving in a chemical solvent. The adhesion between the oxide layer and the copper body is not enough. Early removal will affect the bonding force between the subsequent outer cladding and the copper body.
[0017] S2, polishing the outer wall of the copper wire.
[0018] Specifically, the burr on the surface wall of the copper wire is mainly removed by means of mechanical processing, and the surface of the copper body is smoothed, thereby increasing the bonding force between the outer cladding layer and the copper body.
[0019] S3, wrapping a polyimide tape on the surface of the copper wire.
[0020] Specifically, the polyimide tape is evenly wound on the surface of the copper wire.
[0021] S4. Make the...
