LTCC raw material tape material, LTCC substrate and preparation method
The invention discloses an LTCC raw material tape material, an LTCC substrate and a preparation method, the LTCC raw material tape is formed by LTCC tape casting slurry, and the LTCC tape casting slurry comprises 40 wt%-50 wt% of an inorganic material component and 50 wt%-60 wt% of an organic material component; the inorganic material is prepared from the following components in percentage by mass: 10 to 60 percent of one or two of BSi glass and BSiAl glass, and 0 to 15 percent of one or two of CaAlSi microcrystalline glass, CaBSi microcrystalline glass and BaBAlSi microcrystalline glass; 10-60 wt% of at least two of Al2O3 ceramic, SiO2 ceramic, ZrO2 ceramic, cordierite ceramic and quartz glass powder; the organic materials comprise a solvent, a dispersing agent, a binder and a plasticizer, and the solvent is an alcohol-ketone mixed solvent. By adjusting the mass ratio of the BSi glass, the BSiAl glass, the CaAlSi microcrystalline glass, the CaBSi microcrystalline glass, the BaBAlSi microcrystalline glass, the Al2O3 ceramic, the SiO2 ceramic, the ZrO2 ceramic, the cordierite ceramic and the quartz glass powder, the LTCC raw material tape and the silver electrode slurry are co-fired and tightly attached, and no bubble or hole exists around the silver electrode.
本发明公开了一种LTCC生料带材料、LTCC基板及制备方法，该LTCC生料带由LTCC流延浆料流延成型，按质量百分比计，LTCC流延浆料包括40wt％～50wt％的无机材料成分，以及50wt％～60wt％的有机材料成分；以无机材料的质量百分比计，无机材料包括：10～60％wt％的BSi玻璃、BSiAl玻璃中的一种或两种，0～15wt％的CaAlSi微晶玻璃、CaBSi微晶玻璃、BaBAlSi微晶玻璃中的一种或两种；10～60wt％的Al2O3陶瓷、SiO2陶瓷、ZrO2陶瓷、堇青石陶瓷、石英玻璃粉中的至少两种；有机材料包括溶剂、分散剂、粘结剂和增塑剂，其中，溶剂为醇‑酮混合溶剂。本发明通过调整BSi玻璃、BSiAl玻璃、CaAlSi微晶玻璃、CaBSi微晶玻璃、BaBAlSi微晶玻璃、Al2O3陶瓷、SiO2陶瓷、ZrO2陶瓷、堇青石陶瓷、石英玻璃粉的质量比，LTCC生料带与银电极浆料共烧贴合紧密，银电极周围无鼓泡，无孔洞。
