Conductive paste (because the conductive phase is mostly silver, so it is referred to as conductive silver paste) is a high-concentration multi-phase suspension dispersion system composed of silver powder, binder phase, solvent and additives. It is made by screen printing or other printing technology Thick film electronic materials for preparing conductive wiring or surface electrodes on the substrate are widely used in various thick film electronic components, sensitive components, touch screens, radio frequency identification tags (RFID), solar cells, membrane switches, flexible circuits and other fields.
The conductive paste is an intermediate product, which needs to be screen-printed into a wet film according to the designed pattern and then undergo a certain curing process to obtain the final conductive film layer. The ideal conductive film layer should have two main characteristics: the geometric shape and thickness of the film layer are strictly controllable; the resistance of the film layer (usually expressed by square resistance) is as small as possible. The conductive film layer is solid (without volatile organic compounds), and its square resistance is affected by the properties of the components in the film layer, including the volume fraction and morphology of the binder (resin) and the functional phase (such as silver powder) , Size, distribution and interface, etc. In contrast, the theory and practice of the relationship between the composition, structure and performance of multiphase solid materials can be used to guide joint research. The strict controllability of the geometric shape and thickness of the conductive film layer mainly depends on the good screen printing characteristics of the paste. In other words, the paste has good screen printing properties, that is, the paste obtains a strictly controllable geometric shape and film thickness through screen printing. The so-called good screen printing characteristics of the slurry is a qualitative description. The various physical and chemical phenomena in the process of screen printing of the slurry into a wet film pattern should be decomposed and analyzed to find the quantitative parameters that affect the characteristics of the slurry screen printing. Can guide the research of conductive paste and evaluate its performance.
