Ceramic PCB board is also called ceramic substrate or ceramic circuit board, ceramic copper coated plate, ceramic substrate refers to the copper foil directly bonded to alumina (Al2O3) or aluminum nitride (AlN) ceramic substrate or other ceramic substrate surface (single or double) on the special process board. The ultrathin composite substrate has excellent electrical insulation performance, high thermal conductivity, excellent soft brazing and high adhesion strength, and can be etched into a variety of graphics like PCB board, with great current-carrying capacity. Therefore, Ceramic PCB board has become the basic material of high power electronic circuit structure technology and interconnection technology.

Ceramic PCB board can do several layers at most, how many layers can be done, is a lot of customers more concerned about the topic. Ceramic PCB board can be made of multiple layers, mostly using HTCC process and LTCC process, but the processing cost is high. At present, Hitech circuit has made 4 layers, 8 layers, 16 layers of Ceramic PCB board, and so on, so far the customer feedback is good.
