LTCC生料带材料、LTCC基板、LTCF-LTCC异质基板及对应的制备方法
本发明提供LTCC生料带材料、LTCC基板、LTCF‑LTCC异质基板及对应的制备方法，以LTCC生料带材料的质量百分比计，包括45～55wt％无机材料成分和45～55wt％有机材料成分；以无机材料的质量百分比计，无机材料包括50～70wt％陶瓷材料和30～50wt％玻璃材料；有机材料包括溶剂、分散剂、粘结剂和增塑剂。本发明中的流延浆料成型效果佳，制备的LTCC生料带与LTCF共烧匹配性好，烧结致密，且LTCC生料带材料的介电常数为4.5～7.0，介质损耗为2.3×10‑3～4.5×10‑3；LTCF‑LTCC异质基板共烧贴合紧密，剪切面没有崩口，可有效避免LTCC层被LTCF层扩散的情况。
The invention provides an LTCC raw material tape material, an LTCC substrate, an LTCF-LTCC heterogeneous substrate and a corresponding preparation method, and the LTCC raw material tape material comprises 45-55 wt% of an inorganic material component and 45-55 wt% of an organic material component based on the mass percentage of the LTCC raw material tape material; the inorganic material comprises the following components in percentage by mass: 50-70 wt% of a ceramic material and 30-50 wt% of a glass material; the organic materials comprise a solvent, a dispersing agent, a binder and a plasticizer. The tape casting slurry is good in forming effect, the prepared LTCC raw material tape and LTCF are good in cofiring matching performance and compact in sintering, the dielectric constant of the LTCC raw material tape material is 4.5-7.0, and the dielectric loss is 2.3 * 10 <-3 >-4.5 * 10 <-3 >; and the LTCF-LTCC heterogeneous substrate is tightly bonded in a co-firing manner, and the shear surface has no collapse opening, so that the condition that the LTCC layer is diffused by the LTCF layer can be effectively avoided.
