Laminated composite magnetic dielectric substrate material and preparation method thereof
The invention belongs to the technical field of electronic materials, and relates to a laminated composite magnetic dielectric substrate material and a preparation method thereof. The ferrite ceramic diaphragms and the dielectric ceramic diaphragms are alternately stacked in proportion to form the laminated structure, and a continuous magnetic circuit without an air gap is formed in the magnetic layer by adopting a laminated compounding mode, so that the magnetic conductivity is hardly influenced, and the magnetic conductivity is greatly improved. Therefore, the magnetic conductivity of the laminated composite magnetic dielectric substrate material can reach the product of the magnetic conductivity of a ferrite magnetic material and the ratio of the total thickness of the magnetic layer to the total thickness of the substrate, and is greatly higher than the magnetic conductivity of a magnetic dielectric composite material obtained by mixing powder traditionally; and a larger implementation space is provided for regulating and controlling the magnetic and dielectric properties of the magnetic dielectric substrate material. The applicable frequency of the laminated composite magnetic dielectric substrate material can cover 1MHz-5GHz, and specific application frequency regulation and control can be realized by flexibly regulating and controlling the magnetic dielectric property of the composite material; the invention provides a simple, feasible and mature preparation process.
本发明属于电子材料技术领域，涉及一种叠层复合磁介基板材料及其制备方法。本发明通过将铁氧体陶瓷膜片和介电陶瓷膜片按比例交替堆叠构成叠层结构，采用叠层复合的方式，在磁性层中形成连续不开气隙的磁路，使得磁导率几乎不受影响，因此本发明叠层复合磁介基板材料的磁导率可达到采用铁氧体磁性材料的磁导率乘上磁性层总厚度与基板总厚度之比，大大高于传统采用粉体混合得到磁介复合材料的磁导率，给调控磁介基板材料的磁性和介电性能提供了更大的实施空间。本发明的叠层复合磁介基板材料，其适用频率可覆盖1MHz～5GHz，并可通过灵活调控复合材料的磁介电性能来实现具体的应用频率调控；且提供了简单易行成熟的制备工艺。
