The Advantages of Copper Bonding Wire Cost Savings
The relatively low cost of copper is one of the reasons for its
appeal as an alternative interconnect material. By replacing gold
wires with copper material, thus replacing the precious metal part,
significant cost savings are possible. In applications that require
increased wire diameters, the usage of copper bears a
disproportionately high impact on the saving effect. Superior
Performance of Copper Wires Copper exhibits significantly better
conductivity than gold or aluminum. Therefore better heat
dissipation and increased power ratings are attainable with thinner
wire diameters. Copper possesses higher mechanical properties
compared to gold. Therefore it displays excellent ball neck
strength and high loop stability during molding or encapsulation.
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!
