CQFP Ceramic Four-Sided Flat Housing AlN HTCC Substrate

Aluminum nitride HTCC substrate is made of aluminum nitride as raw material with accurate thickness and good densification of raw ceramic sheet, using tungsten, molybdenum, manganese and other metal slurry, and the designed circuit diagram is formed on the raw ceramic sheet through drilling, micro-hole grouting, printing and other processes, and then laminated together and sintered at 1500℃~1850℃. Finally through electroplating, brazing and other processes, a monolithic structure of three-dimensional wiring system is formed. Aluminum nitride HTCC substrate has high mechanical strength, good heat dissipation performance, high temperature and corrosion resistance, high wiring density, it 's suitable for electronic components those need to work at high temperature environment, with high thermal stability requirements and large power.
