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
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.
High-speed cameras
| Structure | Sequential, 6 copper layers, 2 flex layers |
| Material | FR4 – Isola DE104 (TG≈135 °C), polyimide |
| PCB thickness | 1,1 mm |
Circuit board technology | Rigid-flex, symmetrical, through connection, Line/space: 100µm/150µm |
| Surface | Chemical nickel/gold |

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.
