System solutions in a minimum of space

Rigid-flex printed circuit boards –
when flexibility solves space problems

Rigid-flex printed circuit boards consist of a combination of rigid printed circuit board and flexible areas made of polyimide, which are inseparably connected to each other and form a unit mechanically and electronically.

When used correctly, rigid-flex printed circuit boards enable optimum solutions for complex installation spaces. An area within a housing can be used in the best possible way. Mechanical movements or vibrations can be absorbed.

Further advantages of rigid-flex PCBs are the dynamic and mechanical load capacity and the resulting 3-dimensional design freedom, simpler installation and the preservation of uniform electrical characteristics.

In addition to the technical advantages, such as the saving of plug-in and line components, this technology also offers economic advantages as the overall price of the product can be reduced.

For symmetrical rigid-flex designs, our Chinese fabrications can provide UL approval (E503852).

Advantages

  • Replacement of rigid PCBs including savings on plug-in and wiring components by combining different parts into a single rigid-flexible PCB
  • More components with less space required
  • Space savings and weight reduction by reducing component size
  • 3-dimensional design
  • Increased reliability and resilience, especially in harsh environments with vibration, acceleration or deceleration
  • Improved signal quality and integrity
  • Reduced logistics by combining multiple components on a single PCB
  • Lower system costs
  • Particularly well suited for miniaturized electronics

Technology spectrum

  • Symmetrical and asymmetrical structures up to 20 layers
  • final thicknesses from 0.8 mm to 3.0 mm
  • several flex layers possible
  • Copper thicknesses for outer layers: from 35 µm to 70 µm
  • Rigid-Flex as HDI PCB possible
