Advantages of ceramic substrate
Different from the traditional glass fiber FR4 substrate, the ceramic material has good high-frequency performance and electrical performance, and has high thermal conductivity, chemical stability, excellent thermal stability and other characteristics that other ordinary substrates do not have.
● High thermal conductivity and high temperature resistance
● Smaller coefficient of thermal expansion.
● Stronger and lower resistance.
● Good insulation performance.
● Low high-frequency loss.
● Excellent thermal stability.
Alumina substrate features:
● Good surface characteristics, providing excellent flatness and flatness.
● Good thermal shock resistance.
● Excellent oil and chemical resistance.
● Low warpage.
● Good stability in high temperature environment.
● Can be processed into various complex shapes.
Aluminum nitride substrate characteristics:
● High thermal conductivity, more than 5 times that of alumina.
● Low coefficient of thermal expansion, which can effectively reduce the thermal stress caused by thermal expansion.
● Higher electrical insulation and smaller dielectric constant.
● High mechanical strength and density.
● Excellent corrosion resistance to molten metal.
● Low dielectric loss and more stable reliability.
Silicon nitride substrate features:
● Has high thermal conductivity
● Good electrical insulation, high hardness
● Low dielectric constant and dielectric loss
● Excellent mechanical strength and thermal shock resistance
● Good anti-oxidation performance and good hot corrosion performance.
● High mechanical strength and density.
