Hot air or hot wind and solvent, however we recommend to choose hot air bonding layer,. because the hot air bonding process is environmentally friendly compared to solvent bonding process, allows faster winding, and has potential for process automation. Very thin coils can be produced with self bonding silk severed litz wire unique construction giving additional space for designers or to help to achieve miniaturization goals.
1.High winding speed. Wind the wire and blow the hot air by heat gun, don’t need to choose glue the adhesive the coils separately, that greatly enhance the winding speed and quanlity
2.Solderable without pre-stripping of insulation. Recommended soldering temperature
380-420℃for several seconds,
3.Thin walled overcoat allows small coils.
4.Excellent bonding strengths with hot air bonding.
