Testing Function
Power semiconductor modules (IGBT, SiC power packages) place extreme electrical, thermal, and dielectric demands on ceramic packaging substrates (Al2O3, AlN, Si3N4). Our Ceramic Substrates Testing Solution provides turnkey verification of high-temperature DC electric breakdown from 200°C to 600°C, volume and surface resistivity across wide temperature spans, dielectric constant and loss tangent up to 1650°C, and prolonged leakage current stability under electric stress.
