This invention provides a highly conductive copper paste that cures in an air atmosphere, its preparation method, and its applications, belonging to the field of conductive paste preparation technology. The highly conductive copper paste comprises: 60-80% conductive copper powder; 3-10% polymer resin; 1-3% curing agent; 3-10% first solvent; 1-5% additives; and 7.5-17% particle-free conductive copper ink. The copper salt precursor in the particle-free conductive copper ink is dissolved in the form of copper ions in a mixture of its complexing agent and second solvent. When the highly conductive copper paste is heated and cured in an air atmosphere, the copper ions in the particle-free conductive copper ink are reduced in situ to nano-copper particles, which form welded connections between the conductive copper powder particles, constituting a conductive network composed of micron-sized conductive copper powder and in-situ generated nano-copper weld points. The highly conductive copper paste of this invention has low manufacturing cost, high conductivity, and the potential for room temperature dormancy and heat-triggered decomposition.

This invention relates to the field of electronic materials technology and discloses a low-temperature curing copper-silver composite paste for TGV interconnects and multilayer RDL fabrication and its preparation method. The aim is to address how to suppress the destructive effect of intrinsic copper oxidation on the conductive network during TGV via metallization in an air atmosphere at 200-300°C. This is achieved by using a dense silver layer to coat copper powder to form silver-coated copper composite particles, suppressing the oxidation of the copper core during the heating process. The low-temperature sintering activity of nano-silver powder forms conductive silver bridges before the silver layer dehumidifies, connecting adjacent silver-coated copper particles. A high-temperature resistant resin with a glass transition temperature higher than 260°C after curing is selected as the binder. After curing, the resin is distributed in a discontinuous island-like pattern between the particles, applying compressive stress to enhance contact and simultaneously resisting multilayer wiring processes. The synergistic effect of these three stages allows the sintering reaction to form a stable conductive network in an air atmosphere at 200-300°C, and it is compatible with photosensitive polyimide insulating layers, making it suitable for additive manufacturing of multilayer RDLs for glass via circuit boards.
