Problems solved by technology

[0003] Among the existing capacitor dielectric materials, "ceramic materials" have the advantages of high dielectric properties and low loss, but their bonding performance with PCB boards is poor. At the same time, the powder is easy to agglomerate and the process conditions are harsh, so the practical application is limited.
The "polymer material" has good processing performance, low price, and good bonding performance with the PCB board, but its dielectric constant is very low (generally ε<5)

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to an electronic material with high dielectric properties and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, the requirements for electronic products are more miniaturization, light weight, low cost, multi-function, and high reliability. In the printed circuit board (PCB), passive components are more than 20 times that of active devices, occupying 40% of the space, and the number of capacitors accounts for 40% of passive components, so capacitors occupy an important role in electronic products. status. [0003] Among the existing capacitor dielectric materials, "ceramic materials" have the advantages of high dielectric properties and low loss, but have poor bonding performance with PCB boards, and at the same time, the powder is easy to agglomerate and the process conditions are harsh, so th...
