Cast sheet for ceramic packaging and preparation method thereof
The invention discloses a cast sheet for ceramic packaging and a preparation method of the cast sheet. The cast sheet comprises 90-95 wt% of Al2O3 powder, 2-6 wt% of SiO2 powder, 0.3-1 wt% of CaO powder, 0.5-1.5 wt% of MgO powder, 0.5-1.5 wt% of Cr2O3 powder, 0.7-2 wt% of MoO3 powder, a dispersing agent accounting for 0.6-1.5 wt% of the total weight of the ceramic powder, a binder accounting for 6-10 wt% of the total weight of the ceramic powder and a solvent accounting for 20-30 wt% of the total weight of the ceramic powder, and the SiO2 powder and the CaO powder are prepared according to the mass ratio of 6-15. According to the invention, the Al2O3 powder is subjected to airflow crushing treatment, so that the prepared cast sheet has larger aperture and pore volume, in the sintering process, organic matters decomposed at high temperature are easier to overflow from apertures of the cast sheet, the sintered product has less carbon residue and low dielectric loss, and the signal transmission loss of the sintered product meets the electronic ceramic packaging requirement of a high-frequency device.
一种陶瓷封装用流延片及其制备方法，流延片组成包括Al2O3粉体90～95wt％，SiO2粉体2～6wt％，CaO粉体0.3～1wt％，MgO粉体0.5～1.5wt％，Cr2O3粉体0.5～1.5wt％，MoO3粉体0.7～2wt％，分散剂占陶瓷粉体总重量的0.6～1.5wt％，粘结剂占陶瓷粉体总重量的6～10wt％，溶剂占陶瓷粉体总重量的20～30wt％，SiO2粉体和CaO粉体按照质量比为6～15配制。本发明通过对Al2O3粉体进行气流解碎处理，使得制得的流延片具有较大的孔径和孔容，烧结过程中，高温分解的有机物更容易从流延片的孔缝中溢出，烧结后碳残留少且介电损耗低，烧结后的产品信号传输损耗满足高频器件电子陶瓷封装需求。
