Gold Wire Manufacturing Processes

  • Material Selection: High-purity gold (usually 99.99% or higher) is selected as the base material for the wire.
  • Melting: The gold is melted in a controlled environment, typically in an induction furnace, to ensure consistent material quality.
  • Drawing: The molten gold is drawn through a series of progressively smaller dies to form a thin wire. This process may involve several stages, with each die reducing the diameter of the wire.
  • Annealing: After drawing, the wire undergoes an annealing process, where it is heated to a specific temperature to relieve internal stresses and increase malleability, making the wire more workable.
  • Coating (if required): In some cases, gold wire is coated with a thin layer of another metal, such as palladium, to enhance its properties, like oxidation resistance.
  • Cutting and Spooling: The wire is then cut into specific lengths and spooled for storage and shipping. The wire may also be tested for diameter, tensile strength, and conductivity to ensure it meets quality standards.

Gold Wire Applications

  • Semiconductor Industry: Gold wire is essential for wire bonding in semiconductor packaging, connecting chips to external circuits.
  • LED Packaging: Used in the wire bonding process for connecting the LED chip to the lead frame.
  • Electronics: Applied in high-performance electronics for reliable and stable connections, such as in integrated circuits (ICs) and microelectronics.
  • Jewelry Making: Gold wire is used to craft fine jewelry, including rings, necklaces, and bracelets, due to its aesthetic appeal and malleability.
  • Medical Devices: In medical devices, gold wire is used for critical components that require long-lasting performance and biocompatibility.
  • Aerospace: Gold wire is used in aerospace for reliable and durable wiring in high-stakes environments.

Gold Wire Packaging

Gold Wire is carefully placed in wooden cases or cartons with additional soft materials to support and prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
