99.99% High Purity Au Wire Gold Wire Gold 0.5mm Wire Evaporation Materials
Material of Gold Wire
Gold wire is produced by drawing and bonding Au material with a purity of over 99.99%, containing trace elements like Ag/Cu/Si/Ca/Mg.
Function of Gold Wire
Gold wire serves as an exceptional internal lead material, possessing excellent electrical, thermal conductivity, mechanical properties, and chemical stability. It is primarily used in semiconductor packaging materials (bonding wires, frames, encapsulation materials, solder balls, high-density packaging substrates, conductive adhesives, etc.). In LED packaging, gold wire functions as a conductor, connecting the chip surface electrode and the bracket. When current passes through, it illuminates the chip.
Advantages of Gold Wire
Gold wire boasts high conductivity, corrosion resistance, and good ductility. Widely utilized in integrated circuits, its key advantage lies in its resistance to oxidation, making it a primary choice in packaging applications.
