In this paper, a 1200-V, 150-A IGBT module was designed and fabricated using the nanosilver paste without additional pressure. Comparative tests on thermal-cycling aging were studied between the as-prepared IGBT modules and the commercial modules using high-temp solder. The results indicated that, by the thermal cycling test, the thermal resistance and on-state resistance of the as-prepared IGBT module...
Recently, to accurately study the transient thermal behavior of power modules, a transient thermal measurement system was developed to investigate the transient thermal behavior of insulated-gate bipolar transistor (IGBT) modules attached by nanosilver paste and two kinds of lead-free solders. We found that the transient thermal impedance of IGBT modules attached by nanosilver paste was 9% lower than...
Polymer coatings were doped with low quantity, below 1.5% by weight, of metal and non-metal nanoparticles. The electrical properties, i.e. antistatic properties, volume resistance and temperature characteristics of dissipation factor tan??, were investigated. Antistatic properties were examined by charge decay measurements after corona charging, using JCI 155 apparatus. The results showed that the...
