Semiflex PCB

Semiflex PCBs are partially flexible circuit boards that can be bent over defined areas while the rest of the board remains rigid. This technology allows space-saving, reduces connectors, and improves the reliability of electronic systems. Semiflexible PCBs are often used as a cost-efficient alternative to rigid-flex PCBs and are ideal for applications with moderate bending requirements.

Advantages of Semiflex PCBs

Semiflex PCBs combine the advantages of rigid and flexible circuit boards without requiring additional cables or connectors. They offer a space-saving and cost-efficient solution for compact electronic designs. With their specifically bendable areas, they reduce assembly effort and increase mechanical stability, especially in moving or vibration-intensive applications.

Types of Semiflex PCBs

Depending on requirements, there are various Semiflex variants:

  • FR4-based Semiflex PCBs 6 Standard solution with limited bending capability
  • Polyimide-based Semiflex PCBs 6 Increased flexibility & better thermal properties
  • Multilayer Semiflex PCBs 6 For complex & compact designs
  • Semiflex with reinforced areas 6 Combines flexibility with high stability at loaded spots

Typical Areas of Application

With their innovative design, semiflex PCBs are used in numerous industries. In industrial electronics & IoT they optimize space-saving controllers and sensor modules. In the automotive sector, they are ideal for vehicle lighting and onboard electronics. The medical technology uses them for portable devices, while in aerospace they stand out for their lightweight and high reliability. In telecommunications, they enable powerful antenna and network technologies.

How often can a semiflex PCB be bent?
Semiflex PCBs are designed for a limited number of bending cycles (typically 10-15), while flex PCBs are suitable for frequent bends.
How does a semiflex PCB differ from a rigid-flex PCB?
Semiflex PCBs have limited bendability only in specific areas, while rigid-flex PCBs offer permanent flexibility over multiple areas.
What bend radii are possible with semiflex PCBs?
The minimum bend radius depends on the material thickness but typically ranges from 5 to 15 mm.
