Introduction of common ceramic substrate PCB board
April. 16, 2021Ceramic substrate refers to a special process plate in which at a very high temperature copper foil is directly bonded to the surface(single sided or double sided) of Al2O3 or AlN ceramic substrate. The ultra-thin composite substrate made has excellent electrical insulation properties, high thermal conductivity, excellent solderability and high adhesion strength, and can be etched into various patterns like a PCB board, and has a large current carrying ability. Therefore, ceramic substrates have become the basic material for high-power power electronic circuit structure technology and interconnection technology.
