How to choose a good ceramic PCB supplier? I think this is the question that most companies will think about when they choose. First of all, what is "good"? Many people will measure from the aspects of word of mouth, product quality, etc., and big brands are good. This kind of thinking has been subtly present in the mind. Of course, this is not wrong, but I want to say: The best for you is the best! Someone will ask how to know that it is not suitable for themselves? First of all, you have to understand some of the differences between ceramic circuit boards in order to make better choices.
In many ceramic circuit boards, ceramic circuit boards have different classifications due to differences in substrate materials and manufacturing processes. Therefore, it is necessary to understand some of the characteristics of different types of ceramic circuit boards to locate it, and to what extent. Alumina ceramic circuit boards and aluminum nitride ceramic circuit boards are widely used in the market. Today we will analyze these two to see if they differ and what areas should be applied.
In process manufacturing, DPC or DBC technology can be selected for surface metallization. Compared with the traditional PCB, both have a more matching coefficient of thermal expansion and high-frequency insulation. But the biggest difference between the two is the thermal conductivity. At the same temperature, the thermal conductivity of the alumina ceramic circuit board is 7-10 times lower than that of the aluminum nitride ceramic circuit board. So the application distinction comes out.
In high-power applications, the choice of heat dissipation is the first step, so aluminum nitride ceramic circuit boards are commonly used in high power. While low power uses traditional metal substrates or fiberglass panels, alumina substrates can be used in some medium power markets.
After having some simple understanding and then choosing, it is better for professional people to customize your work to solve your needs. Folysky is such a company. It has advanced ceramic PCB manufacturing technology in China, has its own technical research and development team, and exquisite craftsmanship to meet different needs and bring you the most suitable products. Slitong ceramic circuit board has become a good brand in the hearts of customers with higher cost performance and better service. Folysky has also become a good ceramic PCB supplier.
