1、 Nano copper paste: a "macroscopic revolution" of microscopic particles

Nano copper paste is a functional paste formed by uniformly dispersing nanoscale copper particles (1-100 nanometers) in organic solvents or resin matrices. Its core advantages stem from the small size effect and high specific surface area of nanoparticles:

Ultra high conductivity: The surface atomic ratio of nano copper particles is high, forming a tight conductive network with a much lower electrical resistivity than traditional copper materials. The nano copper paste developed by Advanced Institute Technology has a resistivity as low as 2.0 × 10 Ω· m, approaching the level of pure copper, meeting the transmission requirements of high-precision electronic devices.

Excellent dispersibility: Through unique surface modification technology, nano copper particles are evenly distributed in the slurry, avoiding agglomeration and ensuring the formation of a flat and dense conductive layer after printing, thereby improving product reliability.

Low temperature process adaptation: Nano copper paste can be sintered and formed at a low temperature of 150-200 ℃, solving the problem of damage to flexible substrates caused by traditional high-temperature processes and providing key support for flexible electronic manufacturing.

Environmental protection and cost advantages: Compared to precious metal silver paste, copper resources have lower costs and abundant reserves. The production process is free of heavy metal pollution and complies with environmental standards such as RoHS.
