Thick Film Substrate Materials

Thick film substrates are made from high-quality ceramic materials.  Ceramics include:

Alumina (Al2O3):   
Most commonly used substrate.  Good thermal conductivity, most economical material.

  • 96% to 99.6%
  • 0.010” to 0.080” thickness
  • Area up to 4.5” x 4.5”

Aluminum Nitride (AlN)
Better thermal conductivity than alumina. 

  • 0.020” to 0.040” thickness
  • Area up to 4” x 4”

Berrylium Oxide (BeO)
Best thermal conductivity.  Conducts heat almost as well as copper

  • 99% BeO
  • 0.015” to 0.080” thickness
  • Area up to 4” x 4”
