What are Wire Bonding Capillaries?

Wire bonding capillaries are high precision ceramic bonding tools used in semiconductor and microelectronic assembly to form electrical interconnections between a device die and a package substrate or leadframe. They are a critical component in ball bonding and bumping processes, where fine metal wire is guided, shaped, and bonded with controlled force, heat, and ultrasonic energy.

In ball bonding applications, the bonding wire, typically gold, copper, or silver, is fed through the central hole of the capillary. A free air ball is first formed at the wire tip and is then pressed onto the bond pad on the device. The capillary then controls wire looping and forms the second bond, commonly referred to as the stitch bond, on the substrate or leadframe.

Key characteristics of wire bonding capillaries include:

  • Ceramic tools that transmit force, heat & ultrasonic energy during bonding process
  • Critical to ball formation, placement accuracy, looping and second bond consistency
  • Geometry and surface finish tailored to wire material, diameter and pad pitch design
  • Available in a wide range of designs for stud bumping and ball bonding applications
