1. Advantages of ceramic substrate pcb:
2. The ceramic substrate pcb is made of ceramic material, which is an inorganic material and is environmentally friendly;
3. The ceramic substrate itself is insulated and has high insulation performance. The insulation volume value is 10 to 14 ohms, which can carry high power and high current.
4. The ceramic substrate pcb has good thermal conductivity, and the thermal conductivity of different ceramic materials is different. Among them, the thermal conductivity of alumina ceramic substrate PCB is about 30W; the thermal conductivity of aluminum nitride ceramic substrate PCB is above 170W; the thermal conductivity of silicon nitride ceramic substrate PCB is 85w~90w
5. The ceramic substrate has strong pressure resistance
6. The ceramic substrate pcb has high frequency performance, low dielectric constant and low dielectric loss.
7. The ceramic substrate pcb has high temperature resistance, corrosion resistance and long service life.
Disadvantages of ceramic substrate pcb: the production cost is higher, because the ceramic substrate pcb is easily broken, the scrap rate is relatively high, the board is worn out, it is difficult to make a high-level ceramic substrate PCB, and the cost is high.
