Development of Cu Recycling for Micro Cu Powders Used in Electronics-Grade Cu Slurry

Project Details


This project will be aimed to enhance recycle secondary copper technology, electroless Ag-coated Cu process and electronic grade conductive copper slurry development, greatly improve the recovery of secondary copper purity, recycling copper preparation copper powder electronic grade copper slurry application of high value technology development, and to promote Taiwan's high-value industry respectively. The overall goal will apply the development of domestic production of high purity copper powder and electronic grade conductive copper paste technology, and will replace the expensive imported copper powder to create the advantages of domestic industry to enhance international competitiveness. The project will divide into two subprojects, being cooperate with GIGA Solar Materials Corp., to develop the fabrication technology for high-purity copper micro-, nanomaterials. The first subproject will focus on the copper resource purification technology and copper powder preparation research. The second subproject will focus on the material characterizations and the development of electroless Ag-coated Cu nanowires and electronic grade conductive copper slurry technology. The project will be integrated the research of the subprojects, implement the circular economy and create high-value technology to promote the relevant application industry, to help domestic recycling, metal powder, solar cells and capacitor-related industries, so that will achieve the domestic economy and sustainable development in country.
