Factory production 95% alumina ceramic plate
The core component of the alumina ceramic plate is a ceramic material mainly composed of alumina ceramics. Alumina ceramics have good electrical conductivity, mechanical strength and high temperature resistance. The thermal conductivity of alumina ceramic substrate is very high, generally between 30W and 50W. The thinner the sheet, the better the thermal conductivity, and the thicker the sheet, the lower the thermal conductivity. But the overall heat conduction effect is more than 100 times that of ordinary PCB. Due to its superior performance, alumina ceramic substrates are more and more widely used in modern society, meeting the needs of daily use and special performance industries.
