99.9999% 0.028mm 0.04mm Self Adhesive OCC Enameled Copper Wire

• Semiconductor Packaging: Used as bonding wire in integrated circuit (IC) packaging, replacing gold wires to reduce costs while maintaining performance
• Precision Coil Windings: Ideal for headphone voice coils, miniature speakers, precision sensors, and medical instrument probes

The wire surface is coated with a self-adhesive layer (thermosetting or thermoplastic). After winding, coil turns automatically bond and cure through heating or solvent treatment, forming a unified structure without frames or additional fixing materials. This ensures shape stability, shock resistance, and enables more compact designs.
