导电银浆的丝网印刷适性与流变学

Screen Printing Suitability and Rheology of Conductive Silver Paste

导电银浆的性能参数对指导产品开发具有重要的意义。通过分析导电银浆在丝网印刷成膜过程中的受力情况,指出了丝网印刷的主要特性参数;结合流变学的基本概念和模型,建立了特性参数与量化的流变学参数之间的对应关系;重点介绍了浆料流变学性质的连续旋转、振荡和法向拉伸等测试方法的基本原理和应用。

The performance parameters of conductive silver paste are of great significance to guide the development of products. Through analysis of the stress of conductive silver paste in the screen printing film forming process, the main characteristic parameters of screen printing were obtained. According to the basic concept and model of the rheology, the corresponding relationship were established between the characteristic parameters and quantitative rheological parameters. The basic principles and applications of continuous rotation, oscillation and tensile test method of rheological properties of silver paste were also introduced in detail.
