Product Specification

6-Layer Rigid-Flex PCB (2R+2F+2R) Manufacturing for Complex Electronic Systems

The product shown above is a customized 6-layer rigid-flex PCB (2R+2F+2R) developed for a customer requiring complex routing, flexible interconnection, and high-reliability structural integration.

This advanced 6-layer rigid-flex PCB manufacturing solution integrates two rigid outer layers with two internal flexible layers and two additional rigid layers, enabling superior electrical performance, structural stability, and space optimization.

At Ring PCB, we specialize in high-precision rigid-flex PCB manufacturing and full turnkey PCB assembly services, delivering one-stop PCB and PCBA solutions for demanding industrial and high-tech applications.

What Is a 6-Layer (2R+2F+2R) Rigid-Flex PCB?

A 2R+2F+2R stack-up consists of:

• Two rigid outer layers

• Two flexible core layers

• Two internal rigid layers

This configuration provides:

• Higher layer density

• Enhanced signal routing flexibility

• Improved EMI shielding

• Increased mechanical strength

Compared to standard multilayer boards, 6-layer rigid-flex PCB manufacturing offers better system integration while reducing the need for connectors and cable harnesses.

Key Features & Advantages

1️⃣ Complex Circuit Integration

This 6-layer rigid-flex PCB supports high-density component layout and complex signal routing, ideal for advanced electronic modules.

2️⃣ Flexible Structural Design

The flex section allows dynamic bending or fixed folding, making it suitable for compact devices and irregular housing structures.

3️⃣ Enhanced Reliability

By eliminating traditional interconnect cables, rigid-flex PCB manufacturing reduces failure points and increases long-term durability.

4️⃣ Space & Weight Reduction

A 6-layer rigid-flex PCB design minimizes board count and mechanical connectors, reducing overall product size and weight.

5️⃣ One-Stop PCB & PCBA Manufacturing

We provide integrated rigid-flex PCB manufacturing and turnkey PCBA services, including fabrication, component sourcing, SMT assembly, testing, and quality control.

Technical Challenges in 6-Layer Rigid-Flex PCB Manufacturing

Producing a 6-layer rigid-flex PCB requires:

• Precise lamination control between rigid and flex materials

• Accurate layer alignment

• Controlled copper plating thickness

• Reliable via formation across rigid and flex interfaces

• Stable impedance control

Our engineering team performs DFM analysis to optimize stack-up and manufacturability before production.
