What is Rigid-Flex High Frequency PCB? |
|
|
|
| |
|
1.Rigid-Flex PCBs: Strength, Flexibility, and Precision |
|
|
|
| |
|
A Rigid-Flex High-Frequency PCB combines rigid sections (using high-frequency materials like Rogers RO4350B or RO4003C) for structural support and signal performance with flexible polyimide (PI) sections for bending and twisting. This design is ideal for space-constrained, high-reliability applications, making it suitable for aerospace, medical devices, communication systems, automotive electronics, and consumer electronics. |

2. Key Features of Rigid-Flex PCB |
|
|
| |
|
2.1 High-Frequency Performance:
Utilizes high-frequency materials (e.g., Rogers RO4000 series) to ensure low dielectric loss and stable signal transmission.
2.2 Flexible Design:
The flexible section allows bending, folding, or twisting to adapt to complex spatial layouts.
2.3 High Reliability:
The rigid section provides mechanical support, while the flexible section reduces connection points, enhancing overall reliability.
2.4 Lightweight:
Reduces the need for connectors and cables, lowering weight and volume.
2.5 Customization:
Can be designed with varying layers, thicknesses, and material combinations to meet specific requirements. |

4. Strengths of Rigid-Flex PCB built on FR-4 and poyimide |
|
|
| |
|
When it comes to the Rigid-Flex PCB, I invariably think of 6-Layer Rigid-Flex PCB built on FR-4 and poyimide with immersion gold and 90ohm impedance control.Using it as an illustration, we will make a detailed account.
This high-performance 6-layer rigid-flex PCB is expertly designed for car tracker GPS applications, combining FR-4 and polyimide materials to deliver exceptional reliability and flexibility. With a total thickness of 1.4mm, it features half-ounce copper on inner layers and 1-ounce copper on outer layers, ensuring optimal signal integrity. The design includes 90-ohm impedance control on both outer layers and the inner flexible circuit, while immersion gold-plated pads guarantee seamless SMT assembly.
Built using premium Shengyi base laminate and manufactured to IPC 6012 Class 2 standards, this PCB meets the highest quality requirements. Whether for prototyping or mass production, it’s the perfect solution for advanced automotive tracking systems. |
