0.35mm 2uew Self Bonding Adhesive Enameled Copper Magnet Wire for Speaker Voice Coil

Product Description

Product Description

 

Self bonding copper wire refers to a wire with self-adhesive properties formed by coating the outer layer of insulating paint film with a layer of self-adhesive paint. Compared with ordinary enameled copper wire, self bonding wire not only has its own wire diameter specification It is small and does not need to use auxiliary materials such as skeleton during the winding process, which can greatly reduce the weight and volume of the winding, and is more suitable for micro and small electronic components and electronic products.

3. Self-bonding Film

Compared with the hot melt bondable magnet wire   wire and the alcohol-soluble bondable magnet wire, the self-adhesive paint material is different, the strength of the hot melt is higher, and the ability to resist re-softening and loose circles is strong. The alcohol-soluble self-adhesive wire bonding process is simple and the heat resistance is poor.

Alcohol self-bonding: The self-bonding effect is achieved by adding an appropriate solvent (such as industrial alcohol) to the wire during the winding process. The recommended solvent is ethanol or methanol.

Hot air self-bonding: Hot air is to achieve self-bonding effect by blowing hot air on the wire during the winding process. The temperature of the hot air at the winding is usually between 120ºC-230ºC

Power-on self-bonding: Electric self-bonding is achieved by electric current (resistive heating). The required amperage depends on the shape and size of the coil. Power-on self-bonding is recommended for products with wire diameter above 0.10mm (38AWG)

Oven self-bonding: Oven self-bonding is achieved by placing the finished coil in an oven to heat it to achieve self-adhesive effect. In order to achieve uniform heating of the coil, according to the shape and size of the coil, the temperature of the oven usually needs to be between 120 ° C and 220 ° C, and the required time varies from 5 to 30 minutes.
