Short Description:

Self-bonding wire is a special wire that overcoated with a bonding layer on the top of base insulation, with this bonding layer, wires can be adhered to each other by heating or solvent. The coil wound by such wire can be fixed and formed by  solvent method.

This self-bonding wire is designed for voice coil motor of mobile phone. Custom-made for different process and application condition.

Solvent Self-Adhesive

Solvent self-adhesion is achieved by applying a suitable solvent (such as industrial alcohol) to the wire during the winding process. The solvent can be brushed, sprayed or coated on the winding during the winding process. The typical recommended solvent is ethanol or methanol (concentration 80~ 90% is better). The solvent can be diluted with water, but the more water used, the more difficult the self-adhesive process will become.




Simple equipment and process 1. Solvent emission problem

2. Not easy to automate

1. Solvent residue may damage the insulation

2. The inner layer of the coil with a large number of layers is difficult to dry, and it is usually necessary to use an oven to self-adhere the residual solvent to completely evaporate.

Usage Notice

1. Please refer to the product brief to select the appropriate product model and specifications to avoid unusable due to non-conformance.

2. When receiving the goods, confirm whether the outer packaging box is crushed, damaged, pitted or deformed; during handling, it should be handled gently to avoid vibration and the whole cable is lowered.

3. Pay attention to protection during storage to prevent it from being damaged or crushed by hard objects such as metal. It is forbidden to mix and store with organic solvents, strong acids or strong alkalis. If the products are not used up, the thread ends should be tightly packed and stored in the original packaging.

4. Enameled wire should be stored in a ventilated warehouse away from dust (including metal dust). It is forbidden to direct sunlight and avoid high temperature and humidity. The best storage environment is: temperature ≤ 30 ° C, relative humidity & 70%.

5. When removing the enameled bobbin, the right index finger and middle finger hook the upper end plate hole of the reel, and the left hand supports the lower end plate. Do not touch the enameled wire directly with your hand.

6. During the winding process, put the bobbin into the pay-off hood as much as possible to avoid the solvent contamination of the wire. In the process of placing the wire, adjust the winding tension according to the safety tension gauge to avoid the wire breakage or the wire lengthening due to excessive tension. And other issues. At the same time, the wire is prevented from coming into contact with the hard object, resulting in damage to the paint film and short circuit.

7. Solvent-adhesive self-adhesive wire bonding should pay attention to the concentration and amount of solvent (methanol and absolute ethanol are recommended). When bonding the hot-melt adhesive self-adhesive wire, pay attention to the distance between the heat gun and the mold and the temperature adjustment.
