Curamik Ceramic Substrates

Our engineers have an international reputation for machining to a very high degree of accuracy.

Curamik ceramic substrates.

The doping process provides enhanced robustness and improved properties when exposed to mechanical constraints. Our curamik performance substrates are based on si 3 n 4 ceramics joined with copper by active metal brazing amb. At ceramic substrates we operate with a bank of nine cnc s twelve traditional lathes and mills producing fully engineered machinable ceramic components six days a week. Our curamik thermal substrates offer the best thermal conductivity in the industry.

The low coefficient of thermal expansion of the ceramic substrate means they outperform substrates based on metal or plastic. Dbc direct bond copper a high tem. 3 µm 7 µm 8 2 p all. Download the complete technical data sheet with all curamik advantage features.

Curamik high temperature high voltage substrates consist of pure copper bonded to a ceramic substrate such as al2o3 alumina aln aluminum nitride hps zro2 doped or silicon based si3n4 silicon nitride. Contact our sales specialists for further information about curamik advantage. Aln ceramic substrates market globally by 2025. Our curamik power plus substrates are based on zr doped al 2 o 3 hps ceramic.

The substrates ain direct bond copper dbc provides an adjusted thermal expansion coefficient which is closer to that of silicon and results in little tension in the solder layer between chip and substrate.
