Ceramic PCB Board

Ceramic PCB boards play an important role in the field of electronic technology. Ceramic PCB boards are different from ordinary PCBs.

What is a Ceramic PCB Board?

Ceramic PCB is also called ceramic substrate, ceramic circuit board, ceramic copper clad laminate, and ceramic PCB board refers to copper foil directly bonded to alumina (Al2O3) or aluminum nitride (AlN) ceramic substrate or other ceramic substrate surface at high temperature. (single-sided or double-sided) on special craft boards. The ultra-thin composite substrate made of ceramic PCB board has excellent electrical insulation properties, high thermal conductivity, excellent solderability and high adhesion strength, and can etch various graphics like PCB boards. Ceramic PCB boards Has a great current carrying capacity. Therefore, ceramic PCB boards have become the basic material for high-power power electronic circuit structure technology and interconnection technology.

Advantages and Disadvantages of Ceramic PCB Board

1. Ceramic PCB board has very good thermal conductivity and insulation performance

The ceramic PCB board is made of ceramic substrate. The ceramic substrate itself has very good insulation and thermal conductivity. The thermal conductivity is 25~230w, and the insulation resistivity is negative 14 of 10. It can be seen that the insulation performance of the ceramic PCB is very good. .

2. The dielectric constant of the ceramic PCB board is very low, the dielectric loss is small, and it has very good high-frequency performance. The dielectric loss of the alumina ceramic PCB board is less than 0.0003@1MHz, and the dielectric loss of the aluminum nitride ceramic PCB board is less than 0.0005@1MHz. The dielectric loss is small, the high-frequency performance is good, and it is widely used in the field of high-frequency communication.

3. The ceramic PCB board is high temperature resistant, corrosion resistant, environmentally friendly, can work at high frequency for a long time in a very complex environment, and has a long service life.

4. The size of the ceramic PCB board is small, the general size is less than 120mm, the special customization is 200mm, 230mm, the general price is more expensive, and the material cost of the ceramic PCB board is higher. In addition, because the ceramic PCB board is made of ceramic material, it does not have better toughness like the FR4 board. It can be more than one meter long and wide. In addition, the ceramic PCB board is easy to break during the processing process, and the scrap rate is high.

The Maximum Number of Layers of Ceramic PCB

The maximum number of layers of ceramic PCB boards is a topic that many customers are more concerned about. Ceramic PCB boards can be made of multiple layers, more than three layers and more than a dozen layers, and HTCC technology and LTCC technology are mostly used, but the processing cost of ceramic PCB boards is relatively high.

How to Quote Ceramic PCB Board

The quotation of ceramic PCB board needs to provide drawings, process requirements and quantity for evaluation and quotation. The price of aluminum nitride ceramic PCB boards is higher than that of alumina ceramic PCB boards, and the price of multilayer ceramic PCB boards is higher than that of single-sided and double-sided ceramic PCB boards. The more difficult it is, the production cycle and price of ceramic PCB boards will also increase.

The above describes the ceramic PCB board from the four aspects of the definition, advantages and disadvantages, number of layers, and quotation of the ceramic PCB board. The market prospect of the ceramic PCB board is broad. Ceramic PCB board companies and factories need to continuously improve process capabilities, product quality and delivery capabilities, so as to grasp the market opportunities of ceramic PCB boards.
