Why to use Ceramic printed circuit boards (Ceramic PCBs)

Basically, the multilayer ceramic PCB got the materials which include beryllium oxide, boron nitride, and silicon carbide which helps in providing the super performance in thermal conductivity and thermal expansion.

In the industry and direction of PCB, the aluminum with other substrates and the traditional FR-4 aren't considered as suitable in order to develop the smart and high power application. Due to the extensive advancement in science and technology along with the inventions of powerful electronic products in the field of miniaturization, the ceramic is now ruling the PCB industry.

Using ceramic PCBs can also result in a lower overall system cost and be especially cost-effective for dense packages since you have parallel processing of layers. So, using the ceramic PCBs and its technology over the traditional PCB application can result in a great saving in terms of cost and the thermal conductivity of ceramic PCB provides so much enhanced power in the PCB technology.

Most of the PCB users find ceramic board an advantage as compared to the other traditional PCB made up of different materials. The reason behind this superiority is due to providing the high thermal conductivity and the low thermal expansion for the substrates in electronic circuits. Due to this, the performance of the ceramic PCB is increased and made it more versatile due to its less complex design. Their uses include proximity sensors, high power circuits and much more.

Along with its super thermal properties and the expansion coefficient, the ceramic PCB works at the temperature of up to 350 C. This will create the smaller package size that offers the enhanced performance and also no water absorption.

Difference between FR4 Boards, Ceramic PCB & MCPCB?

There are essentially 3 to 4 types of printed circuit boards. The standard PCB is FR4 and the metal core (MCPCB) is also widely used. The ceramic PCB is a type of MCPCB in some terms. You can use other PCBs as there is nothing wrong while using the FR4 but the ceramic PCB has some exceptions which made them superior from the traditional FR4 PCB. It’s good to know how they are different from one another and which you should choose.

Basically it depends on your demands that how you want to use this PCB. Specifically, the applications for which you’ll be using the PCB. Let’s have a look at the pros and cons of the FR4 boards, MCPCB, and the ceramic PCB.

We can classify it by material: Al2O3 ,SiC ,BeO ,Aluminium Nitride (AlN). Specific material parameters are as follows:

Fr4 vs. MCPCB

The very big reason and an important one too for not using the FR4 and going with ceramic PCB are because of heat transfer. The metal cores like beryllium oxide and aluminum nitride are really thermally conductive. But the FR4 boards are not good in that. So, if you want to use the board in the application where heat is a major cause, just like LED lighting, you should be going away from them FR4 boards. Choosing the ceramic PCB or the metal core PCB in this regard would help you in tackling the heat as metal carry more heat, and this could save your board from reducing its life. In this application, you won’t be using the FR4 PCB for sure. The other MCPCB materials along with the beryllium oxide and aluminum oxide can contain steel alloy and copper. Steel alloys are much better in proving the easiness as compared to copper and aluminum but it’s not good in heat transfer. As copper as the ability to dissipate and transfer the heat when part of the printed circuit board. But the problem is its somehow expensive from the other PCBs. So many companies who are on a budget or who want to purchase in great number would choose aluminum. But still, alumina PCB is still better from FR4 in heat dissipating. Aluminum PCBs

For most businesses, the best solution that meets their cost expectation is the MCPCB with that aluminum base. As it has better thermal conductivity and good rigidity for a very reasonable price. So, no matter if you order the MCPCB and don’t specify the copper, you will preferably get the aluminum PCB
