Hot Air Self Bonding 0.030mm Enameled Copper Wire for Speaker Winding

Ultra-fine enamelled copper wire is widely used in miniature electronic devices, mobile phones, computers and other tiny electronic products for conductive connection, signal transmission and circuit wiring.

Due to the small diameter and softness of the wire, ultra-fine enameled copper wire can easily realize high-density wiring in a small space, making electronic equipment smaller and more efficient,its excellent temperature resistance ensures the stability and reliability of electronic equipment during long-term operation.
