Dielectric constant regulation and control method and preparation method of ceramic substrate material
The invention relates to the technical field of ceramic materials, in particular to a dielectric constant regulation and control method and a preparation method of a ceramic substrate material, and the ceramic substrate material comprises the following components: at least two kinds of glass powder with different particle sizes, ceramic powder and an organic carrier; the dielectric constant of the ceramic substrate material is regulated and controlled by adjusting the ratio of the glass powder with different particle sizes. The glass powder at least comprises large-particle glass powder with the median particle size of 2.5-2.8 microns and small-particle glass powder with the median particle size of 1.1-1.4 microns. The compact degree of the sintered substrate is controlled by adjusting the particle size grading of the glass powder in the LTCC slurry, so that the ceramic substrate material with the adjustable dielectric constant is obtained under the condition that the mechanical property fluctuation is small, and the LTCC slurry has wide application prospects in the fields of electronic ceramic elements, electronic device packaging and the like.
本发明涉及陶瓷材料技术领域，具体为一种陶瓷基板材料的介电常数调控方法及制备方法，所述陶瓷基板材料的成分包括：至少两种不同粒径的玻璃粉体、陶瓷粉体和有机载体；通过调节不同粒径的所述玻璃粉体的配比，对所述陶瓷基板材料的介电常数进行调控。所述玻璃粉体至少包括中值粒径在2.5‑2.8微米的大颗粒玻璃粉体和中值粒径在1.1‑1.4微米的小颗粒玻璃粉体。本发明通过调节LTCC浆料中玻璃粉体的粒径级配，来控制烧结基板致密程度，从而实现在力学性能波动较小的情况下，得到介电常数可调的陶瓷基板材料，在电子陶瓷元件、电子器件封装等领域具有广阔的应用前景。
