Alumina Substrate
Alumina substrate, also known as aluminum oxide substrate or ceramic substrate, is primarily composed of aluminum oxide (Al2O3). The excellent electrical, thermal, and mechanical characteristics of alumina, a well-known ceramic material, lead to its selection. The manufacturing process of alumina substrate involves synthesizing high-purity alumina powder, shaping it into desired shapes, and sintering the material at high temperatures. The sintering process promotes densification, resulting in a strong and dense Al2O3 substrate with outstanding physical properties.
