Multilayer PCBs with four or more copper layers are used in almost all areas of electronics.
Rewiring is possible on up to 30 layers.
The miniaturization of electronic devices requires the implementation of more and more functionalities in less and less space. At the same time, the density of components on a circuit board is increasing.
Multilayer PCBs with four or more copper layers are therefore used in almost all areas of electronics. Rewiring is possible on up to 30 layers, which are generally connected with through-hole plating. Thicknesses of up to 3.20 mm are possible in PCB production.
The main challenge with multilayer PCBs and their structure is the optimal handling of the very thin layers of material. Fully automated production processes ensure consistent quality, even with high layer multilayers.
Our precisely designed registration processes guarantee maximum congruence of all layers - even with the finest structures. With insulation thicknesses starting at 50 μm for cores and prepregs, the layer structure can be customized for many electrical requirements (EMC, impedance, etc.).
Intelligent software is used to calculate the resin filling and insulation thicknesses for the layer structures. Cost and quality optimizations can also be carried out
| Number of layers | 4 – 30 |
| PCB thickness | 0.50 - 3.20mm |
| Materials | FR4, hybrid of various FR4s possible |
| Glass transition temperature Base material | 135°C; 150°C; 170/180°C |
| Aspect ratio vias | ≤ 1:10 |
The specified values represent the maximum power spectrum and may be limited in certain combinations.

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.
