Palladium Coated Copper Wire with Ultra Fine 0.01mm diameter for Integrated Circuits
Palladium Coated Copper (PCC) bonding wire was developed and has now become the most dominant bonding material used in fine wires of diameters of <50 microns being used as substitute for more expensive gold. Thermosonic wire bonding is the most popular form of interconnection for most semiconductors. It requires the creation of a molten Free-Air Ball (FAB) at the end of the wire that is then ultrasonically-pressed on semiconductor bonding pads to form the first bond. When using PCC wires however,forming gas is needed during the FAB formation to prevent the oxidation of Cu that is usually exposed during the process. The exposure of Cu is caused by the Pd coating flowing within the FAB due to differences in surface tension between the component metals
Features:
* Gold-plated/palladium bonding wire made of 4N high-purity copper material with a certain proportion of trace elements added;
* In addition to the characteristics of conventional copper wire, it also has high strength,low curvature, high toughness, and anti-oxidation
* Chemical characteristics, the arc isimpact-resistant and the welding wire is corrosion-resistant;
* Surface gold/palladium special bonding wire developed for IC packaging;
What Is Palladium Coated Copper Bonding Wire?
Palladium Coated Copper Bonding Wire is easier to bond than your standard bare copper wire. The Palladium (Pd) coating allows for high performance and stable bonding, all within a wider bonding. The Pd coating controls the oxidation build up that can occur on the surface of the copper wire.

Application:
Applications of palladium-plated copper wire: Can be used in integrated circuits, semiconductor packaging, LED packaging, optoelectronic packaging, etc.
Advantages:
Good Conductivity & Thermal Conductivity:
Copper has excellent electrical and thermal conductivity. The palladium plating doesn't much affect these. It transmits current and heat well for electronic signal and heat dissipation, ensuring component operation.
Strong Oxidation Resistance:
Palladium is a stable precious metal. The palladium layer on the wire surface stops copper core contact with air and moisture, preventing oxidation, prolonging wire life and enhancing device reliability.
Higher Hardness:
Palladium plated copper wire is harder than pure copper. It keeps shape and stability during wire bonding, reducing contact issues from deformation. But watch for cratering in wire bonding.
1.What kind of Enameled copper wire do Winner produce?
We focus on research and development of selfbonding magnet round copper wire, fine polyurethane magnet wire, selfbonding litz copper wire and selfbonding silk covered wire.
2.What's diameters available of the Enamelled copper wire ?
We specialize in fine and ultra fine enamelled copper wire,diameters available of our products is Φ0.018-0.50mm.
3.What's selfbonding enameled copper wire?
Selfbonding enamelled copper wire is a special type of enamelled wire with an additional adhesive enamel overcoat such as thermoplastic resin.This adhesive has a bonding feature, which is activated
by heat or solvents.
Once activated the adhesive bonds turn to turn windings into a compact self supporting coil.
The use of selfbonding wire may offer cost and manufacturing advantages in some winding applications
as bobbins, tape, varnishing, or impregnation may be eliminated.
4. Is possible to get any sample of selfbonding enamelled copper wire that you have in production?
