  Self Bonding Wire  
 

Magnet wires are made by spread insulating or multilayer in each kind of conductor line material after dryings. Self-bonding Wire is a kind of special magnet wire where the conductor is enamelled with two layers. The inter layer is insulation film and outer layer is a self-bonding film. The characteristics and usage are based on the conductor, coating and varnish film thickness. The main uses are on the speaker coils, buzzer coils, micro vibrant motor coils, actuator coils of HDD, pick up coils, antenna coils, sensor coils and the other electronic products etc.
