Rigid-flex PCB technology combines rigid FR4 layers with flexible polyimide layers to create compact, high-reliability interconnection solutions. The product shown above is a customized 4-layer rigid-flex PCB (1R+2F+1R) developed for a customer requiring local coil plating and low-resistance inductance control performance.
This advanced rigid-flex PCB manufacturing solution integrates mechanical flexibility with electrical stability, making it ideal for compact industrial electronics, precision control modules, and high-performance power systems.
At Ring PCB, we specialize in rigid-flex PCB manufacturing and PCB assembly services, providing one-stop PCB and PCBA solutions for customers worldwide.
A Rigid & Flex PCB is a hybrid printed circuit board that combines rigid PCB sections with flexible circuit (FPC) areas into a single integrated structure. This design allows electronic products to achieve both mechanical stability and flexible interconnections, making it ideal for compact, high-density, and space-constrained applications.
Rigid & Flex PCB technology is widely used in medical devices, industrial control, automotive electronics, aerospace, and advanced consumer electronics. By reducing connectors and cables, rigid & flex printed circuit boards improve signal reliability, reduce assembly complexity, and enhance overall product durability.
Ring PCB provides customized Rigid & Flex PCB manufacturing and assembly as part of our One-Stop Service for PCB and PCBA service solution, supporting customers from prototype to mass production.
A well-designed Rigid & Flex PCB offers significant advantages over traditional rigid or flexible boards alone.
Integrated rigid PCB and flexible circuit structure
High-density interconnection and compact layout
Flexible bending areas for 3D assembly
Support for ENIG surface finish and hard gold fingers
FPC with PI stiffener for enhanced mechanical strength
Reduced connectors and assembly steps
Improved signal integrity and reliability
Enhanced mechanical durability in dynamic environments
Optimized space utilization and product miniaturization
Suitable for complex, high-precision applications
With advanced manufacturing processes, Ring PCB ensures every Rigid & Flex PCB meets strict performance and quality requirements across various industries.
Manufacturing a Rigid & Flex PCB involves higher technical complexity compared to standard printed circuit boards:
Layer Alignment: Precise registration between rigid and flex layers is critical for reliability.
Material Combination: Managing different materials (FR-4 and polyimide) requires strict process control.
Impedance and Signal Integrity: Fine trace width and spacing demand high-precision etching.
Mechanical Reliability: Bending areas must withstand repeated flexing without cracking or delamination.
As an experienced EMS provider, Ring PCB overcomes these challenges through mature process control, advanced equipment, and skilled engineering teams.
The following specifications are based on the product shown in the image and are for reference only.
Actual parameters can be customized according to customer design requirements.
