LTCC raw material tape material, LTCC substrate and preparation method
The invention provides an LTCC raw material tape material, an LTCC substrate and a preparation method, and the LTCC raw material tape material comprises the following components in percentage by mass: 40-50 wt% of an inorganic material and 50-60 wt% of an organic material, the inorganic material comprises the following components in percentage by mass: 20 to 60 weight percent of Al2O3 ceramic, 10 to 50 weight percent of ZrO2 ceramic, 25 to 38 weight percent of CaAlSi microcrystalline glass and 0 to 3 weight percent of sintering aid; the organic material comprises an alcohol-ester mixed solvent, a dispersing agent, a binder and a plasticizer. Mixing the raw materials according to the mass ratio, and casting to obtain an LTCC raw material tape material; and after being subjected to overlying forming, the substrate is put into a sintering furnace to be roasted, and the LTCC substrate is obtained. The dielectric constant of the LTCC substrate is 7.0-8.3, the dielectric loss of the LTCC substrate is 0.003-0.005, the bending strength of the LTCC substrate is 300 MPa or above, and the LTCC substrate is good in cofiring matching performance with silver and gold electrode slurry.
本发明提供一种LTCC生料带材料、LTCC基板及制备方法，以LTCC生料带材料的质量百分比计，包括40～50wt％无机材料和50～60wt％有机材料；以无机材料的质量百分比计，包括：20～60wt％Al2O3陶瓷、10～50wt％ZrO2陶瓷、25～38wt％CaAlSi微晶玻璃和0～3wt％烧结助剂；有机材料包括醇‑酯混合溶剂、分散剂、粘结剂和增塑剂。按上述原料的质量比混合，流延得到LTCC生料带材料；将其叠压成型后放入烧结炉中焙烧，得LTCC基板。本发明中的LTCC基板的介电常数为7.0～8.3，介质损耗为0.003～0.005，抗弯强度300MPa以上，且与银、金电极浆料共烧匹配性好。
