Get to know the Benefits of Ceramic Printed Circuit Boards

Ceramic Printed Circuit Boards (PCBs) are the latest innovation that has gained popularity in the last few years. Ceramic PCBs use an organic compound called polyimide as the solder paste and a ceramic (alumina, beryllia, phosphate) as the substrate material. These PCBs are an alternative to the conventional PCB technology that is based on FR-4 glass epoxy laminated with a thin layer of copper. The market for ceramic PCBs is still in its infancy but it is growing rapidly due to their unique properties as well as cost effectiveness. They offer several benefits over traditional FR4 based PCBs, including thermal conductivity, chemical resistance, electrical insulation and high thermal shock resistance. They are widely used for military and aerospace purposes, but have recently made their way into the consumer electronics industry, particularly IoT devices. This post analyzes the benefits offered by these PCBs over regular FR4 PCBs and their application.

Benefits of Ceramic Printed Circuit Boards Over Traditional PCBs

There are several benefits of using ceramic printed circuit boards. They help reduce the size and weight of the end product significantly, whilst augmenting the energy efficiency. High quality surface finish (due to its flatness), high temperature resistance, and low dielectric constant are their other notable advantages. Additionally, ceramic boards are durable and can resist abrasion, which means they can be used in areas where there is high mechanical stress. The other beneficial features of ceramic PCBs are as follow:

  • Ceramic printed circuit boards can accommodate high component density on a single board because the ceramic substrate is purer than glass fiber reinforced epoxy boards and FR-4 boards. This means that they can house smaller components while still maintaining the same mass and footprint.
  • Ceramic boards are several times more resistant to high temperature than FR4. They also have much higher heat deflection temperature than traditional FR4. This provides the board with better performance in extreme temperature conditions, which in turn extends the life of the board.
  • Ceramic PCBs are more resistant to atmospheric moisture than FR4 boards.
  • Ceramic PCB boards are not made from epoxy glass but from ceramic, which is much more durable and rigid than epoxy glass.
  • Ceramic boards are denser than traditional PCBs, which assures high signal integrity. Additionally, these boards are faster and more reliable than traditional boards.
  • Owing to their rigidity, these boards are less prone to damage, which is often caused by vibration or dropping. They also have minimal flex, so they can be used in applications with high heat or high impact.
  • Another advantage of ceramic PCBs is that they are fireproof. This can make them a good choice for products that need to meet certain guidelines regarding flammability and thermal resistance. Ceramic boards have a high thermal resistance because of its low heat conduction. The thin layer of ceramic fiber on the surface of PCBA can block heat from flowing into the board, and at the same time, it can protect the conductive traces from cracking when exposed to too much heat.

Major Application Areas of Ceramic Printed Circuit Boards

Ceramic PCBs are often used in harsh environments and microelectromechanical systems (MEMS). They are commonly used in space, military, aerospace, and automotive applications. All these industries have high-reliability requirements. They can't afford to fail when it is needed the most!

A few of the applications of ceramic PCBs are:

  • High-power circuits
  • Chip-on-board modules
  • Proximity sensors
  • Solid state relays (SSR)
  • Solar panel arrays
  • Transmission/Receiving modules
  • Multi-layer interconnect boards
  • Analog/Digital PCBs
  • LEDs
  • Automotive light systems
  • Solar cells

Ceramic PCBs are popular these days as they have some amazing benefits over traditional PCBs to improve the performance of end products. The rise in demand has triggered growth of PCB manufactures who offering the service of designing and fabricating ceramic boards. The most important factor to consider when choosing a PCB manufacturer is quality and experience. If the finished PCB doesn’t meet your industry quality guidelines, there are all chances that your end product won’t succeed. That’s why it is important to choose a manufacturer that takes quality seriously like Twisted Traces.
