PCB or printed circuit boards are made by printing conductive pathways into a board that connects transistors, resistors, and integrated circuits.
In the case of Ceramic printed circuit boards (Ceramic PCB), the conductive pathways are printed in ceramic baseboards. This essentially improves the performance quality of such circuit boards. The ceramic used in this case is not the typical ones that are utilized in floors; instead, it is a special kind of material called ‘fine ceramic.’ It is engineered with different chemical substances for specific uses.
A ceramic printed circuit board is made of metal cores. Aluminum nitride boards are suitable for high thermal conductivity. The main drawback of it is the cost. Aluminum nitride boards cost a lot. For less cost, many use aluminum oxide boards, which provide less thermal conductivity comparing to the previous one. In this case, one can increase the conductivity by using silver traces covered with glass. The glass is primarily used for protection. For using in delicate devices, silver corrosion can become a problem, and for this issue, some use gold plating.
Ceramic PCB is comparatively more prices than other PCB. But if we think deeply, it is actually a cheaper option because it requires less maintenance for being a high-quality product. This is why many tech industries are switching to Ceramic PCB to provide their customers with better and safer products.
