Design Parameters
Plated-through slots, also called PTH slits (PTH = plated through hole), plated elongated holes , plated-through milling or PTH routing, are producible from 0.6mm width. Smaller…
This section of the design aid provides you with all the information you need on the mechanical processing of PCBs.
Milling - lists the available milling cutter diameters and provides tips on the…
Scoring (also known as v-cut) is used for mechanical pre-separation of circuit boards. A V-shaped breaking line is formed in the circuit board with a precision cutting tool. Please observe the…

Multilayer circuit boards comprise outer and inner layers (copper layers) and help to achieve more complex, denser wiring structures. Multilayer circuit boards are pressed from the following…
A prepreg (from pre-impregnated) is fibreglass impregnated with resin. The resin is pre-dried, but not hardened, so that when it is heated, it flows, sticks, and is completely immersed. Prepregs are…
In the following you can see the defined layer buildups for PCB prototypes with 4, 6 and 8 layers. These can be selected free of charge in our PCB calculator.
If you wish to have different layer…
For layer buildups of circuit board series you may use any combination of available prepregs and cores with a moderate surcharge. Please observe rules for layer buildups. We would be happy…
The following is an example of the layer buildup of Flexible circuit boards. Usually, these requirements are met. If a special layer buildup is required, please contact us: We will be happy to…
Possible variants
The standard layer buildups for Rigid-Flex circuit boards are as follows. Variations from these defaults are of course also possible, please contact us. We would be happy to…
