The conductive silver paste product integrates metallurgy, chemical industry and electronic technology. It is a high-tech electronic functional material MLCC, conductive ink, solar cell electrode, LED, Electronic components such as printed and high-resolution conductors, membrane switches/flex circuits, conductive adhesives, and sensitive components. Metal silver powder is the main component of conductive silver paste, and its conductive properties are mainly realized by silver powder. In a sense, high silver content is beneficial to improve its conductivity, but when its content exceeds the critical volume concentration, its conductivity cannot be improved. The size of the silver particles is related to the conductivity of the silver paste. Under the same volume, the particles are larger, the contact probability is lower, and the space is larger, which is occupied by the non-conductive resin, which blocks the conductor particles, and the conductivity decreases. On the contrary, the contact probability of small particles increases, and the electrical conductivity increases. The general particle size can be controlled at 3-5μm, which is only equivalent to 1/10-1/5 of the mesh size of a 250-mesh ordinary wire mesh, so that the conductive particles can smoothly pass through the network and be densely deposited on the substrate to form a full conductive pattern. . The shape of silver particles is closely related to electrical conductivity. The conductive particles used to make the conductive print are preferably platelet-shaped, flat and needle-shaped, especially platelet-shaped particles. The round particles are in contact with each other, and the tabular particles can form surface contacts. After printing, the flake particles overlap each other at a certain thickness, showing better conductivity.
Storage conditions:
Flake Ag Powder should be kept sealed in a dry,cool environment,should not be exposed to air,prevent oxidation and be affected with damp and reunion,affect the dispersion performance and using effect.The other should try to aviod stress,in accordance with the general cargo transport.
