Our curamik Ceramic substrates offer high heat conductivity, high heat capacity and thermal spreading of the substrates' thick copper cladding, making our substrates indispensable to power electronics. The low coefficient of thermal expansion of the ceramic substrate means they outperform substrates based on metal or plastic.

Benefits

  • Great heat conductivity and temperature resistance
  • High insulation voltage
  • High heat spreading
  • Low coefficient of thermal expansion outperforms metal or plastic substrates
  • Adjusted expansion coefficient enables chip on board
  • Efficient processing of master cards and single pieces
  • Range of formulations optimized for various power applications
