The typical features of Ceramic Substrate For Thin Film Circuits are low dielectric loss, lowand stable dielectric constant, high mechanical strength, and good chemical stability. Although the alumina content is different, the electrical property is hardly affected. However, the mechanical property and thermal conductivity vary greatly. Substrates with low purity have more glass and higher surface roughness; substrates with higher purity are smoother, denser and have lower dielectric loss.
Application Ceramic Substrate For Thin Film Circuits are widely used in microwave/millimeter wave circuits, optical communication, medical, automotive, LED, photovoltaic, military industry and other fields.
