Mobility of the future: power electronics with hybrid circuit boards instead of ceramics

Press Release /

Scientists at the Fraunhofer Institute for Laser Technology ILT, in collaboration with project partners, have succeeded in developing a novel industrial manufacturing process, one that makes it possible to use low-cost FR4 circuit board substrates in power electronics, for example in electric motors. Compared to conventional power electronics made of ceramics, the so-called hybrid printed circuit boards are not only much more versatile, but also up to 20 times cheaper. This could close a gap in the market in the medium term and, thus, make an important contribution to the mobility of the future.
