According to the “China Conductive Copper Paste Market Research and Investment Strategy Report (2019 Edition)” released by Limu Information Consulting, electronic paste (conductor, dielectric, resistance) is a new type of material, which is more efficient Environmental protection, energy saving, low cost and other characteristics have been widely used in solar cells, aerospace, sensitive components, resistance networks, displays, electrode materials for lithium-ion batteries and other technical fields.
Conductive copper paste is a mixed conductive paint composed of a copper powder, a thermosetting resin, an organic solvent and other modifiers.、At present, the conductive pastes that have been studied more are gold paste, silver paste, copper paste, etc. Au has good stability, but its price is more expensive, which is not conducive to industrial production. The price of Ag is slightly lower than that of Au, and the conductivity is better, but Ag + migration phenomenon will occur during the use process, which will cause the performance of the product to decrease, which limits its range of use. Cu, as a valence base metal, has a wide range of sources, and its conductivity is only lower than Ag and higher than Au, which has been favored by people in recent years.
