What is Ceramic PCB?

A ceramic PCB is a type of PCB made from ceramic materials, such as alumina (Al2O3), ALN (aluminum nitride), or Beryllium Oxide (BeO). These materials are prepared by using thermal conductive ceramic powder and organic adhesive under the condition of below 250℃. Ceramic powders are not easy to made, especially for aluminum nitride powder, this is one of reasons that why ALN ceramic PCB is more expensive.

There are some different methods to make ceramic PCBs, commonly in the market are thick film, DBC, DPC and thin film technology. Different types of ceramic circuit boards have its unique characteristics. May you heard about HTCC, LTCC and AMB, they are also the ways to make ceramic PCBs, but there just a few manufacturers can make. Here is a HTCC ceramic PCB that we made.

Why Ceramic PCBs are popular used?

Different from the traditional FR-4 PCB (wave fiber), ceramic PCBs have good high-frequency properties, electrical properties that organic materials can’t achieved. It is a new generation of large-scale integrated circuits and power electronics module ideal packaging materials. The main advantages of ceramic circuit board including:

Higher thermal conductivity
More matched thermal expansion coefficient (CTE)
Lower resistance
Good weldability and can be used in high temperature
Good insulation
Lower high-frequency loss
High density assembly available
No organic ingredients, resistance to cosmic rays, high reliability in aerospace
No oxide layer in copper layer, so it can be used for a long time in a reducing atmosphere
