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
