    Aluminum is liked for its value-effectiveness and good enough electric conductivity but may possibly require added protecting measures in opposition t oxidation.

    Copper Wire Bonding

    Copper delivers most appropriate conductivity at shrink costs yet poses challenges corresponding to oxidation manage all over processing.

    Silver Wire Bonding

    Silver is less more commonly used however promises excellent conductivity; even though, check issues occasionally prohibit its utility.

    Wire Bond Quality Control Measures

    Ensuring high nice in wire bonding requires rigorous control measures which includes:

  • Visual Inspection
  • Pull Testing
  • Shear Testing
  • X-ray Inspection
