Ceramic substrate contrast aluminum substrate, copper substrate
Release time:
2023-07-13
The thermal conductivity of ceramic substrates is relatively high due to the absence of insulating layers. The thermal conductivity of common ceramic substrates is as follows: alumina ceramic substrates: 20-30 W/m · k aluminum nitride ceramic substrates: 170-320 W/m · k silicon nitride ceramic substrates: the theoretical thermal conductivity of single crystal silicon nitride can reach 400W/(m.k). Advantages: ① the thermal conductivity of ceramic substrates is much higher than that of metal substrates such as aluminum and copper; ② because it is not metal materials, ceramic substrates have the best electrical insulation performance. Disadvantages: ① Ceramic substrates are also special materials and need to be customized, and the order production cycle is relatively long; ② Ceramic substrates are brittle, with relatively poor machining performance and relatively low yield after processing; ③ In comparison, the comprehensive cost of ceramic substrates is equivalent to copper substrates.
ceramic substrate is relatively high due to the absence of insulating layer. The thermal conductivity of common ceramic substrates is as follows:
alumina ceramic substrate: 20-30 W/m · k
aluminum nitride ceramic substrate: 170-320 W/m · k
silicon nitride ceramic substrate: the theoretical thermal conductivity of single crystal silicon nitride can reach 400W/(m.k)
advantages:
① The thermal conductivity of ceramic substrate is much higher than that of aluminum-based, copper-based and other metal substrates
② Because it is not a metal material, the electrical insulation performance of ceramic substrate is the best
Disadvantages:
① Ceramic substrate is also a special material and needs customization, and the order production cycle is relatively long;
② Ceramic substrate is brittle and has relatively poor machining performance, the yield rate after processing is relatively low;
③ Compared with the comprehensive cost ceramic base and copper base are comparable.
