♦ What is Ceramic PCB?                                                 

Ceramic PCB refers to a special process board in which copper foil is directly bonded to the surface (single or double sides) of alumina (Al2O3) or aluminum nitride (AlN) ceramic substrate at high temperature. The ultra-thin composite substrate has excellent electrical insulation performance, high thermal conductivity, excellent soft solderability and high adhesion strength. It can also be etched with various patterns like PCB boards, and has a large current carrying capacity.

♦ Features of Ceramic PCB

• • Excellent insulation performance: Ceramics are good insulators that can effectively prevent current leakage and interference, improve circuit stability and reliability, and ensure the safe operation of electronic equipment.

  • ​​High chemical stability: Strong corrosion resistance, high resistance to chemical corrosion, can maintain stable performance in harsh chemical environments, suitable for chemical and other fields.

  • ​​Good dimensional stability: Excellent dimensional stability and precision in high temperature environments, low thermal expansion coefficient, can prevent circuit board deformation, and ensure that electronic equipment can work normally in different temperature environments

♦ Applications of Ceramic PCB 

• • ​​High-power LEDs: outdoor lighting, car headlights, display screens, etc., efficient heat dissipation and extended life.
  • RF/microwave communications: 5G base stations, radars, satellite communications, stable transmission of high-frequency signals.
  • ​​Power electronics: power modules, electric vehicle inverters, high temperature resistance, high current carrying capacity.
  • ​​High reliability fields: aerospace, military equipment, medical equipment, stable operation in extreme environments.
  • ​​Industrial/IoT: industrial sensors, laser equipment, smart hardware, miniaturization + high temperature resistance requirements.
