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!
