Ceramic PCB - Outstanding Heat Transfer and Cost Performance

aluminum nitride pcb manufacturing

Overview of Ceramic PCB

  • PCBONLINE offers quality ceramic PCB (aluminum nitride), which has higher thermal condutivity than the FR4, and is far cheaper than the MCPCB (copper, aluminum, and iron).
  • Ceramic PCB is versatile due to its enhanced performance and less complex design. Its uses include proximity sensors, high power circuits etc, and it is suitable to develop the smart and high power applications. If you are looking for cheap PCB with high thermal resistance, don't miss ceramic PCB by PCBONLINE.

To ensure the long service life and high stability of the ceramic PCB, PCBONLINE selects ceramic materials with high-temperature resistance, strong acid resistance, alkali resistance, high thermal conductivity, and low thermal expansion coefficient. Also, we strictly uses 96% alumina ceramic baseboard and 100% aluminum nitride ceramic baseboard. All these bring out the excellent quality of the ceramic PCB by PCBONLINE.

FR4 vs. ceramic vs. metal core

  • Both FR4 PCB, ceramic PCB, and MCPCB are all widely used, but they are very different in heat transfer. For the ceramic, the core like beryllium oxide and aluminum nitride are really thermally conductive. The MCPCB also does well in heat transfer and transfer even more heat, but it is somehow expensive. As for the FR4 boards, they are not good in heat transfer. Thus choosing the ceramic PCB or the metal core PCB in this regard would help you in tackling the heat, and this could save your board from reducing its life.
  • If you want to use the circuit board in the application where heat is a major cause, like LED lighting, on a budget, you had better use the ceramic PCB, which has good thermal conductivity and is less expensive than the metal core PCB.
