How to choose a good ceramic PCB supplier? I think this is something that most companies think about when they make their choices. What is "good" in the first place? Many people will measure from the direction of word of mouth, product quality and so on, and the big brand is good, this idea has been imperceptibly existing in the brain. Of course, it is right to think so, but I want to say: suitable for oneself is the best! Some people will ask how to know whether it is suitable for them? First of all, you must understand some of the differences between ceramic circuit boards in order to make a better choice.
In many ceramic circuit boards, because of the different substrate materials and manufacturing processes, ceramic circuit boards have different classifications. Therefore, it is necessary to understand some characteristics of different types of ceramic circuit boards to locate it and what range it is suitable for. Alumina ceramic circuit board and aluminum nitride ceramic circuit board are widely used in the market. Today, we will analyze these two, and see what the differences are and what areas should be applied.
In terms of process manufacturing, DPC or DBC technology can be selected for surface metallization. Compared with the advantages of traditional PCBS, both have a more matched thermal expansion coefficient and high frequency insulation. But the biggest difference between the two is the thermal conductivity, at the same temperature, the thermal conductivity of alumina ceramic circuit board is 7-10 times lower than that of aluminum nitride ceramic circuit board. Hence the application distinction.
In high-power applications, the choice of heat dissipation is the first step, so aluminum nitride ceramic circuit boards are widely used in high-power applications. Small power is used in the traditional metal substrate or glass fiber board, so in some medium power markets alumina substrate can play its own value.
After having some simple understanding, and then to choose, it is not as good as professional people to make professional customization for you to solve your needs. Fuli Tiansheng is such an enterprise, with advanced ceramic PCB manufacturing technology in China, has its own technology research and development team, exquisite technology to provide customization, to meet different needs, to bring you the most suitable products.
