摘要
主要针对LTCC(Low Temperature Co-fired Ceramic)滤波器电气连通率较低的问题进行了相关研究。通过比较,发现自制的LTCC滤波器端口导带露出端偏薄,从而导致在端口印上导带之后与中间层导带在端口处的电气连接性能不佳。通过进一步的分析,发现导致滤波器端口导带过薄的原因有两个,一是生瓷切片时刀口的带瓷,二是烧结过程中导体浆料与瓷体材料的收缩率不一致导致导体内缩。最后针对性地提出了相应的改进措施,获得了最优化的工艺技术方案。
This paper mainly studies the problem of low electrical connection rate of the LTCC filter.By comparison,The self-made LTCC filter has a thin side at the exposed end of the tape,which results in poor electrical connection with the intermediate layer conduction band at the port after the conductor is printed on the side.Through further research and analysis,it is found that there are two reasons why the side conduction band of the LTCC filter is too thin.The first factor is that the edge of the porcelain is sliced with porcelain knife,and the second factor is that the shrinkage of the conductor paste and the ceramic material during the sintering process is inconsistent,which causes the conductor to be indented inside.Finally,the corresponding improvement measures are proposed in a targeted manner,and the optimized process technology solution is obtained.
