Product Definition

Silver‑filled electrically conductive epoxy is a composite resin system where finely dispersed silver flakes or particles are embedded within a thermosetting epoxy matrix. The silver content typically ranges from 30–70 wt %, creating a percolating network that delivers electrical resistivity in the range of 0.0001–0.001 Ω·cm. The matrix is engineered to provide low viscosity for dispensing, rapid cure at 150–200 °C, and low outgassing for semiconductor cleanroom compatibility. The resulting material offers strong bond strength, excellent thermal conductivity, and resilience under repeated thermal cycling, making it the adhesive of choice for die attach in high‑density ICs, power modules, and emerging wide‑bandgap devices.
