Thick copper PCBs, manufactured using pure etching technology, are the first choice for high currents
and are characterized by structures with copper thicknesses from 105 to 400 µm.
This classic PCB is your first choice when high currents are unavoidable: the thick copper PCB, manufactured using pure etching technology.
Thick copper PCBs are characterized by structures with copper thicknesses of 105 to 400 µm. These PCBs are used for high currents and to optimize thermal management. The thick copper enables large conductor cross-sections for high current loads and favors heat spreading.
The design is usually a multilayer design or a double-sided PCB. With this PCB technology, it is also possible to combine fine layout structures on the outer layers and thick copper layers in the inner layers.

Edge metallization
In order to improve the EMC protection of a circuit board, to create an electrical contact to the housing of the assembly or to meet increased cleanliness requirements, the front sides of the circuit board contour can be metallized.
Milled vias
It is possible to produce application-specific components with so-called milled through-holes. The resulting circuit boards can be soldered onto another circuit board as components (interposer) due to their front-side contacting option.
Contour processing
Contour production: milling and scoring
