Curamik Ceramic Substrates

Dbc direct bond copper a high tem.

Curamik ceramic substrates.

Curamik provides two technologies to attach the substrate with the copper. Useable area 127 mm x 178 mm 0 05 copper peeling strength 4 0 n mm 50 mm min for dbc with 0 3 mm cu thickness 10 0 n mm 50 mm min for amb with 0 5 mm cu thickness platings electroless ni. Partial discharge free substrates free of partial discharge for power modules 1 7 kv. Aln ceramic substrates market globally by 2025.

Our engineers have an international reputation for machining to a very high degree of accuracy. Our curamik thermal substrates offer the best thermal conductivity in the industry. Our curamik power plus substrates are based on zr doped al 2 o 3 hps ceramic. These substrates are ideal for applications that demand a long lifetime high power density and robustness.

The low coefficient of thermal expansion of the ceramic substrate means they outperform substrates based on metal or plastic. 3 µm 7 µm 8 2 p all.

These substrates offer a longer lifetime and greater reliability and performance than alumina substrates and it comes at a competitive price point. 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. 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. 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.

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.
