Electronic components have to handle a steadily increasing amount of functions in the tiniest of spaces. At the same time, power transmission must work optimally at the interfaces and the heat must be dissipated quickly and efficiently.
Roll clad strips bring ideal conditions for exactly this topic. The combination of thick wire, bonding ribbons and AlSi roll clad materials permits particularly flexible thermal as well as electrical connections and thus a good heat dissipation while simultaneously making use of the widest process windows.
As a specialist with many years of experience in the production of roll clad strips, we develop the ideal solution for your requirements. We supply you with matched materials that meet the highest demands – particularly with regard to such growing requirements as surface cleanliness, for example.
Whenever materials reach their limits due to physical or chemical properties, roll clad strips from Heraeus could be your solution. The combination of different materials unites the advantages of each material in a multi-layer system.
You therefore enjoy the benefits of all materials used. With our broad materials and process portfolio and our expertise, we ensure that our product is a perfect match for your customer-specific requirement.
