Ceramic Printed Circuit Boards Compare to Flexible PCBs

The word ceramic conjures images of pottery baking in a kiln, but this material could also play an essential role in electronics. It has an inherent high thermal conductivity, which means it can do a fantastic job of balancing the heat in electronic devices, preventing overheating and prolonging their lifespans.

The electrical insulation of ceramic printed circuit board is just as good as its thermal properties, protecting components from unwanted currents. This feature is ideal for industries that require PCBs to withstand harsh environments, such as oil and gas exploration, aerospace, and military applications. The superior electrical resistance of ceramic is also a big advantage, as it protects against electromagnetic interference (EMI) and electromagnetic compatibility issues.

In addition, ceramic has a low coefficient of thermal expansion, meaning it will still function well even at high temperatures. This makes it a great choice for industrial electronics, power semiconductor modules, and smart power devices. Moreover, the copper used in ceramic PCBs is able to endure high temperatures without oxidation, making it more resistant to corrosion and aging. This also makes it a popular choice for manufacturers of high-speed boards that must operate at high speeds. The high thermal conductivity of ceramic also helps to reduce the temperature of the copper layers, ensuring that they do not become too hot and damaging components.

When it comes to manufacturing, ceramic is very easy to work with and can be fabricated through a number of methods. The fabrication process of a ceramic PCB starts with applying the circuit pattern onto metal foil using photo-lithography techniques. The circuit pattern is then etched away with medium or low-power RF CO2 lasers to create the holes required for connection. Finally, the circuit is plated with copper and gold to connect the different layers of the board together.

If you’re interested in exploring the benefits of a ceramic circuit board, consider working with a trusted PCB manufacturer. Look for a company with ISO 9001 certification and rigorous quality assurance and testing protocols. Evaluate their manufacturing capabilities and capacity, as well as their ability to produce a variety of sizes, shapes, and traces.

Whether you’re building a small prototype or an advanced multi-layer circuit, a ceramic PCB is a great choice. Their insulating and thermal conductivity make them an excellent choice for any project, while their superior electrical insulation and EMI/EMC performance make them perfect for industrial, medical, and military electronics. Considering these advantages, it’s not surprising that ceramic is fast becoming the preferred option for many companies.
