Your benefits

  • Symmetrical and asymmetrical stack-ups
  • Choice of several technologies for applications
  • More than one flexible layer possible
  • Impedance across bending area also possible
  • Self-supporting, stable 3D structures without additional assembly
  • Cost savings through replacement of plug and cable connections
  • Optical flexibility through the individual orientation of separate LEDs in lighting applications

We are happy to support your project at every step along the way.

Three-dimensional PCBs make optimum use of restricted installation space. Parts of a circuit that are interconnected across various PCBs or board segments can also replace connectors and leads. What is more, 3D PCBs can increase package density, reduce weight, increase module reliability and open up new design possibilities while reducing overall system costs.

Multi-dimensional boards can be constructed by various methods using a variety of structures and materials. We can offer you a number of different technologies so that your 3D circuit board is implemented in the best possible way. Each of the three processes uses different structures and has different technical characteristics, design advantages and limits.

Motor controller for fan cooling

Structure4-layer multilayer, 70µm copper
MaterialFR4 TG150°C Panasonic R-1566W
PCB thickness1,7 mm
Circuit board technology12mm, 8mm and 2mm wide copper profiles on an inner layer and an outer layer for 60 and 15 amperes
Special featuresEight half-bridges have to be connected to the connectors by 4x15A = 60A conductors. Heat dissipation from the half-bridges has to be carried via a bending edge to a PCB tab that is glued to an aluminium heat sink in the casing.

When designing and producing a 3D PCB there is a large number of parameters to consider. That is why we advise you to talk to us at a very early stage of development. Through our online advice service or on-site workshops we can discuss the technical aspects and special considerations that such PCB types involve right from the start. We are also happy to help you with technical optimisation features or cost reduction measures.
