High currents of up to several hundred amperes are not uncommon in printed circuit boards. To ensure that the power electronics still function optimally, a lot of copper is needed in the right places on the PCB. We have the right technology for your high-current project.
High currents of up to several hundred amperes are not uncommon today. To ensure that the power electronics still function optimally, a lot of copper is needed in the right places on the circuit board. At the same time, fine conductor structures for control tasks need to be placed on a circuit board.
With a broad technology portfolio for thick copper PCBs, we offer a reliable basis for power electronics requirements - tailored to your project. Our broad product range includes pure high-current PCBs as well as the combination of power and control electronics. Additional functions, such as 3D designs, increase the functionalities and application possibilities.

Optimize high-current PCBs for motor controls: Electronics practice
When realizing a high-current printed circuit board, there are many parameters to consider. You should therefore contact us at an early stage of development. We can discuss the technical aspects and special features associated with these PCB types right from the start via online consultation or an on-site workshop. We are also happy to support you with technical optimizations or cost reduction measures.
The dimensioning of the conductor tracks is subject to a standard set of rules. You can therefore use our practical high-current calculator for your initial calculations. This tool offers you a quick and easy way to calculate the required conductor width for high-current conductors on a FR4 printed circuit board to calculate. Please enter the following values:
