Bumping Wires

Our bumping wire enables the formation of uniform and homogeneous bumps.

Our bumping wires are available with bump formation methods for increasingly smaller, thinner, and higher-density electronics packaging. Bumps can be formed on semiconductor devices, such as ICs and LSIs, and other microelectronic devices at a lower cost and with fewer irregularities.

Features

  • Bumps can be formed with a minimum variance in neck height
  • Bumps can be formed with a minimum variance in shape
  • Suitable for small-volume production
