What is Rigid-Flex PCB?
Overview
A Rigid-Flex PCB is a type of printed circuit board that combines rigid and flexible circuit technologies into a single board. Essentially, it has rigid sections made of standard PCB material (like FR4) and flexible sections made of bendable materials (like polyimide).
Advantages
Saves space and weight compared to separate rigid and flexible boards. Reduces the need for connectors and cables. Provides better durability in dynamic or vibrating environments.
Applications
Compact electronic devices like smartphones, wearables, and medical equipment. High-density or 3D configurations where space is limited.
Our Rigid-Flex PCB Manufacturing Capabilities
At Benlida, we deliver high-precision FR-4 PCB manufacturing with advanced technology, strict quality control, and fast, reliable production from prototype to volume.
Rigid-flex PCB Manufacturing Process
Every rigid-flex PCB undergoes thorough functional testing, automated optical inspection (AOI), and quality verification to ensure reliability and compliance with strict industry standards.
PCB Design & DFM Review
Ensure optimal design and manufacturability before production to prevent errors and improve performance.
Material Preparation
Select and cut FR-4 substrate sheets to the required size and specifications.
Inner Layer Imaging
Transfer circuit patterns onto inner copper layers using photolithography for precise circuit definition.
Etching Process
Remove unwanted copper from inner layers to create the desired circuit patterns.
Layer Lamination
Bond multiple inner layers together under heat and pressure to form the multilayer board structure.
Drilling & Via Formation
Drill holes for component leads and electrical connections between PCB layers.
Copper Plating
Plate drilled holes and surface areas with copper to ensure electrical conductivity.
Solder Mask Application
Apply protective solder mask to prevent short circuits and protect traces.
Surface Finishing
Apply finishes like HASL or ENIG to protect copper and improve solderability.
Electrical Testing & Inspection
Test all circuits for continuity and defects to ensure quality and reliability.
Rigid-flex PCB Design Guides
Designing a rigid-flex PCB requires careful planning to balance flexibility, durability, and electrical performance. Key guidelines include:

Designing a rigid-flex PCB requires careful planning to balance flexibility, durability, and electrical performance. Key guidelines include:
Optimize Bend Areas
Plan flex regions with adequate bend radius to reduce stress and prevent circuit damage during folding or motion
Layer Stackup Design
Separate rigid and flexible layers strategically to maintain signal integrity, thermal performance, and mechanical strength.
Trace Routing
Use consistent trace widths, avoid sharp corners, and minimize vias in flex areas to maintain reliability and performance
Component Placement
Place components on rigid sections whenever possible; avoid placing heavy or high-stress components on flex areas.
Mechanical Support
Add stiffeners, reinforcement, or support frames in critical regions to prevent excessive flexing and mechanical failures.
Thermal Management
Plan copper thickness and heat dissipation strategies to prevent overheating and maintain electrical performance.
Design for Manufacturability
Ensure traces, vias, and pad sizes meet manufacturer capabilities to reduce production errors and improve yield.
