FAQ
Frequently Asked Questions About Ceramic Substrates
These answers cover material selection, metallization, customization and the technical information needed to review a ceramic substrate project.
How do I choose between alumina, aluminum nitride and silicon nitride substrates?
Alumina is widely selected for dependable electrical insulation and cost-effective circuit support. Aluminum nitride is preferred when higher thermal conductivity and a thermal expansion match closer to silicon are important. Silicon nitride is considered for high mechanical strength and demanding thermal-cycling conditions. Final selection should be based on heat load, voltage, mechanical stress, dimensions and cost target.
What is the difference between DBC and DPC ceramic substrates?
DBC bonds relatively thick copper to alumina, AlN or other suitable ceramics and is commonly used where high current and strong heat spreading are required. DPC uses sputtering, photolithography and copper plating to create finer conductor patterns, thinner copper layers and through-hole connections for compact or high-density electronic packages.
Can ceramic substrates be customized from customer drawings?
Yes. Custom dimensions, thicknesses, holes, slots, edge profiles, surface roughness, flatness, polishing and metallization layouts can be reviewed according to the drawing and application requirements.
Which metallization processes are available for ceramic substrates?
Depending on the material, circuit geometry and assembly method, options may include thick-film and thin-film metallization, direct bonded copper, direct plated copper, active metal brazing and other customized conductor or plating systems.
Are ceramic substrates suitable for power modules, LEDs and RF devices?
Yes. Ceramic substrates are widely used where electrical isolation, heat transfer, high-frequency performance, dimensional stability or reliable metal-to-ceramic integration is required. The substrate material and metallization route should be matched to current, voltage, thermal load, frequency and package design.
What information should be included in a ceramic substrate RFQ?
Provide the drawing or Gerber data, substrate material, thermal conductivity target, dimensions, thickness, flatness, surface finish, copper or metallization specification, plating finish, electrical and thermal operating conditions, quantity and project stage.
