This article will explore how to improve the conductivity of nano copper paste in thin film circuits through technological means, and specifically introduce the technology of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum YB5102 Nano Copper PasteApplication in this field.

1、 The conductivity basis of nano copper paste

Nano copper paste is formed by uniformly dispersing nanoscale copper particles in a specific solvent, and its unique physical and chemical properties give it extremely high specific surface area and surface activity. This characteristic makes the transmission of electrons between copper particles more efficient, thereby significantly improving the conductivity of the material.Nano copper pasteThis characteristic makes it an ideal material for preparing highly conductive thin films, electrodes, and other electronic components.

2、 Technical means to improve the conductivity of nano copper paste

1. Optimize the dispersibility of nano copper particles

   The dispersibility of nano copper particles in solvents directly affects their conductivity. By adjusting the type and concentration of dispersants, as well as controlling pH values and other conditions, significant improvements can be madecu nanoparticlesThe dispersion stability. For example, under the conditions of PVP concentration of 10g/L and pH value of 10 ± 0.5, copper colloids that are stable for more than 4 months can be prepared. This stable dispersion helps to form a uniform conductive network in thin film circuits, thereby improving conductivity.

2. Heat treatment modification

   Heat treatment is one of the effective methods to improve the conductivity of nano copper paste. By high-temperature sintering, the organic coating layer on the surface of nano copper particles can be removed, allowing for tighter contact between copper particles and thus improving conductivity. For example, in an Ar gas atmosphere, by raising the temperature to 500 ℃ at a rate of 5 ℃/min and holding for 3 hours, a copper film with a resistivity of 2.5 × 10 Ω· cm can be obtained. Further controlling the organic content in the copper film before sintering can further reduce the resistivity to less than 10 μ Ω· cm.

3. Choose appropriate solvents and additives

   The selection of solvents and additives also has a significant impact on the conductivity of nano copper paste. By selecting appropriate solvents and additives, the dispersion and stability of nano copper particles can be optimized, thereby improving conductivity. For example, using isopropanol as a solvent can prepare copper colloids with good dispersibility and stability.
