High tensile test performance Ultra Fine Wire Gold Bonding Wire for
semiconductor packaging and assembly processes
Ultra-fine gold bonding wire (15-50μm diameter) delivers
exceptional tensile strength (≥12g) for critical semiconductor
interconnects in advanced IC packaging. Engineered with 99.99% pure
gold, it ensures superior electrical conductivity (≤2.0μΩ·cm) and
oxidation resistance, minimizing wire breakage risks in
high-frequency/high-temperature environments. Ideal for automotive
electronics, medical devices, and aerospace applications requiring
MIL-STD-883 compliance.
Key advantages:
- Precision Control: ±0.5μm diameter tolerance for stable loop
formation
- Cost Efficiency: 30% lower breakage rate vs. copper alternatives
- Eco-Compliance: RoHS-certified, halogen-free
- Optimized for wire bonding machines (K&S, ASM), our wire
enhances production yields by 15% while meeting JEDEC J-STD-035
standards. Custom spool lengths (500-2000m) with ESD-safe packaging
available.
Winner manufacture gold wire in diameters as small as 0.0005 inch
(12.5 microns), with highly uniform elongation, tensile strength,
and dimensional properties. All our high-purity gold wire products,
including bonding wires and gold wires, are produced from highly
refined, vacuum-processed metals.

Why Gold Bonding Wire?
Gold (Au) bonding wire is used in a wide range of applications
rangining from high pin-count, ultra-fine pitch microelectronic
devices to high-power discrete components. Au is the preferred
choice of bonding material when a) the contact material is not
compatible with Aluminum (Al) and/or Copper (Cu) b) the contact
area is limited c) the device will be subject to high temperature
or high humidity environments.
The Advantages of Gold Bonding Wire:
• Extreme bond reliability
• A wide processing window
• Low-impact ball and wedge bonding
• Superior looping performance
• High tensile test performance
• Excellent corrosion resistance
• Higher fusing current than standard Al bond wire.
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?
Of course you can!
