Chip Welding Wire Applications

  • IC Packaging: Used for wire bonding between chips and lead frames or substrates in integrated circuit manufacturing.
  • Memory Devices: Ensures stable electrical connections in DRAM, SRAM, and flash memory packaging.
  • Power Semiconductor Modules: Provides strong, heat-resistant bonding for high-power device assembly.
  • LED Packaging: Applied in chip-to-lead bonding for LED modules requiring durability and precision.
  • Sensor and MEMS Devices: Supports fine bonding in miniature electronic sensors and micro-electromechanical systems.

Chip Welding Wire Packing 

Chip Welding Wire will be carefully placed in wooden cases or cartons, with additional support from soft materials, to prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
