Heraeus AlSi:Pads – solderable and adhesive bond pads

With Heraeus bond preforms you achieve more reliable and flexible circuit board designs. Usually soldered onto PCBs and ceramic hybrids, the bond pads allow to apply additional and reliable bond isles fully automated.

The bondpads are characterized by an excellent electrical and thermal conductivity and enable complex functionalities and freedom of design in the tiniest space. With these advantages, they are mainly used in the automotive and high-end segment where miniaturisation and growing requirements play an ever-increasing role.

Profit from our customer-specific advice. Together we will find the optimal configuration and material combination for your application.

Our solderable and adhesive bond preforms offer a particularly high level of conductivity with optimal use of space.

All benefits at a glance:

  • Excellent electrical and thermal conductivity
  • Highest robustness of the bonding connection
  • Bondable with Al thick wire, AlSi thin wire or gold wire
  • Optimal compatability with all solderable and adhesive surfaces
  • Easy and reliable processing by pick-and-place
  • Highest quality thanks to fully automated manufacturing equipment and 100% camera inspection
  • Freedom of design even within the smallest space
  • Compliance with legal regulations: All bond pads are available in RoHS compliant versions and may be used with both lead-containing and lead-free solders.
