Alumina (Al2O3) and aluminum nitride (AlN) compatible. High thermal conductivity substrate for IGBT and power devices.
We provide ceramic substrates for power devices and IGBT applications that require high heat dissipation and high insulation. We offer two types: alumina (Al2O3, thermal conductivity ≧ 24W/m·K) and aluminum nitride (AlN, thermal conductivity ≧ 170W/m·K). Our products support DPC (operating temperature -55 to 350℃) and DBC (-55 to 800℃), with high-precision processing capabilities for maximum dimensions of 128×178mm, minimum pattern width of 0.100mm/pattern spacing of 0.075mm, and minimum hole diameter of 0.1mm.
