A copper coin is a multilayer PCB but with the addition of a solid piece of copper, called a coin, embedded into the PCB’s stack-up. This allows a direct thermal connection from one side to the other or from a specific layer to an outer layer. Learn more in the video.

Nothing affects the PCB’s total cost and reliability as much as the initial design. That is why we have put together our PCB design tools for engineers, designers and anyone else involved in the PCB design or production process.
