| As an ingredient of conductive pastes, the conductive filler plays a crucial role in determining the conductivity of the slurry, and it also affects the welding strength, mechanical strength and other physical properties of the sintered film. The effect of conductive fillers on the slurry performance is reviewed from every aspect of the content, particle size, morphology and surface properties of the fillers. The new graphite nano-packing is also introduced. The future trends for conductive pastes, the authors suggested, should be using nano-packing materials, developing low-cost and environmentally friendly process and expanding the product variety as well as to improving product quality. |
