Iceberg®-PCBs are characterized by structures with mixed copper thicknesses from 105 to 400 µm in outer layers - with a uniform surface topography. High currents and fine conductors can be efficiently combined in a multilayer with optional inner layers.
Increasingly powerful components require more and more power and emit more and more heat loss. To ensure the reliability of the circuit in the long term, the printed circuit board must also meet these requirements. Thick copper/iceberg®-PCBs are characterized by structures with mixed copper thicknesses of 105 to 400 µm in outer layers - with a uniform surface topography. High currents and fine conductors can therefore be efficiently combined in a multilayer together with additional optional inner layers.
These circuit boards are used for large (high) current outputs and for cooling for good thermal management. This is because the copper favors heat dissipation. They are usually designed as multilayer boards.
Whether thermal management or current carrying capacity, thick copper and know-how are required here. KSG can provide you with both to suit your project.

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
