Raw material

Currently there're three basic substrates to make ceramic PCB, including Aluminum Oxide (Al2O3), Aluminum Nitride (ALN) and BeO. Different ceramic circuit board making technology will use different substrate. Because of the length limitations, the details will not be show here. For further information about raw material of thick film ceramic PCB, please click Ceramic Substrate to know.

The size of the common ceramic substrate is 114*114mm. The specifications need to check the manufacturing capability of Best Technology. The picture below is the raw material before cutting:
