High-frequency printed circuit boards

High frequencies require high precision. And great know-how. Together with our customers from the automotive and telecommunications industries, we at KSG have developed into one of the leading manufacturers of printed circuit boards for high-frequency applications in the 24 to 77 GHz range. 

Thanks to our many years of experience in processing special high-frequency materials, we are exactly the right partner for you and your PCB project.

Number of layers2-20
PCB thickness0.25 - 3.20 mm (depending on base material type) 
MaterialsFR4, PTFE, hydrocarbon system, modified FR4 systems 
Glass qualities Some "Square Weave" or "Spread Fibres" and low-Dk glass available 
Layer structure

double-sided printed circuit board, unmixed multilayer, hybrid multilayer
External laminates (laminate technology) for multilayer possible

Technology combinations  countless possibilities on request 

The specified values represent the maximum power spectrum and may be limited in certain combinations.

With high process reliability, etching tolerances of ±15 µm are possible. To achieve this, the processes are specifically controlled for each order and each PCB layout. In addition, inspection processes during production ensure consistent quality.

Solder resist masks

  • Photosensitive coating systems, thermal final curing
  • Colors: green, red, blue, black glossy, black matt, white, yellow
  • Non-photosensitive coating systems, purely thermal curing: white, black


Additional prints 

  • Labeling/equipment
  • Hole filler/through-hole filler
  • Peelable lacquer
  • Heatsink
  • Carbon


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.

Need for Speed - Success factors of a reliable HF printed circuit board

The desire for highly secure, reliable and ever faster data transmission is putting high-frequency and radar applications in the spotlight. It is therefore high time that we at KSG XPERTS took a closer look at this topic. After all, the PCB has a decisive influence on the functionality, costs and reliability of the assembly, from the choice of material to the layer structure and the HF-optimized layout.
