High-Performance Ceramic PCB Manufacturer
Benlida specializes in ceramic PCB manufacturing, offering high thermal conductivity ceramic circuit boards, including alumina ceramic PCB and aluminum nitride PCB (AlN PCB), for high-power and high-reliability electronic applications.
What Is Ceramic PCB?
A ceramic PCB is a circuit board that is made using ceramic materials for its substrate instead of the common FR-4 material. It is usually designed for electronic applications that have the need for efficient thermal management, high electrical properties, and reliability. Ceramic PCBs are distinguished by their increased heat conduction, heat-resistance, and dimensional stability, hence, they are the perfect choice in cases of dealing with heat produced by high-power electronic parts.
Several types of ceramic materials can be employed for producing ceramic PCBs, like alumina (Al2O3) and aluminum nitride (AlN). AlN PCB is one of the most widespread types of ceramic PCBs and is also called aluminum nitride PCB or AlN PCB. Due to its great ability of heat dissipation and insulation, AlN PCB is commonly used in such applications as power modules, LED lighting, semiconductor packaging, RF devices and high reliability electronics.
