With the rapid development of modern communication technology,more and more microwave printed circuit boards(PCBs)are designed and applied,and microwave dielectric substrate materials filled with ceramic powder are selected to meet the requirements of more and more stringent design performance indicators,the processability of microwave PCBs,and the reliability of application scenarios.As a world-renowned company ROGERS,has launched a relatively full range of microwave substrate solutions.In this paper,the performance indicators of two types of ceramic based microwave dielectric materials(hard ceramic substrate and soft ceramic substrate)are introduced.Based on the research on the processability of the two types of ceramic based microwave dielectric materials,the manufacturing process of ceramic based microwave dielectric substrate is given.At the same time,the effectiveness of the technology used is discussed in detail according to the characteristics of related manufacturing processes.
