Conductivity

The conductivity of conductive silver paste is mainly reflected in its conductivity. Conductivity (σ) is an important indicator for measuring the conductivity of materials, usually expressed in Siemens per meter (S/m). According to experimental data, the conductivity of conductive silver paste is usually between 10 ^ 5 S/m and 10 ^ 6 S/m. The conductivity within this range is already very close to that of pure silver (about 10 ^ 7 S/m), which is sufficient to meet the needs of most high-precision electronic applications.
