Key Equipment for Electronic Paste Production: SMIDA Three Roll Mill & Planetary Centrifugal Mixer
Optimizing Conductive Silver Paste Preparation for Photovoltaic & Electronic Applications
2026-05-31
Conductive silver paste is a core raw material for photovoltaic cells and electronic components, and its preparation quality directly affects battery conversion efficiency, component power and product reliability. The whole process relies on two key pieces of equipment from SMIDA: the three roll mill and the planetary centrifugal mixer.
In the batching stage, the SMIDA planetary centrifugal mixer uniformly blends ultra-fine silver powder, glass powder and organic carriers, effectively preventing material separation and ensuring stable initial mixing. This step lays a solid foundation for subsequent dispersion and viscosity control.
For dispersion and refinement, the SMIDA three roll mill delivers powerful shear and grinding effects. It thoroughly breaks up agglomerates, refines particle size, and optimizes the dispersion of functional components. This improves electrical conductivity, oxidation resistance, sintering performance and screen-printing properties, while lowering volume resistivity of the silver paste.
Other auxiliary processes such as viscosity testing, composition adjustment and bottling work as supplements. With stable performance and high precision, SMIDA’s three roll mill and planetary centrifugal mixer have become essential equipment for high-quality electronic paste manufacturing.
