Rigid-Flex PCB - 8-layers Rigid-Flex PCB

8-layers Rigid-Flex PCB

Our 8-layers rigid-flex PCB seamlessly merges the structural stability of rigid boards with the flexibility of flexible circuits, making it a perfect fit for space-constrained and vibration-sensitive applications in instruments and automotive electronics.

Key Features

Hybrid Substrate & Stacked Structure: Built with FR4 (for rigid parts) and PI (for flexible sections), the PCB uses a “FR4 4L + FLEX 4L” stacked design. This ensures both mechanical strength (for rigid areas) and bendability (for flexible regions) while maintaining reliable signal transmission.

Precise Thickness & Copper Plating: The finished board combines a 0.2mm-thick flexible portion and a 0.8mm-thick rigid portion, adapting to tight assembly spaces. With 1 oz (35 μm) copper plating, it offers excellent current-carrying capacity and signal integrity.

High-Precision Manufacturing: Boasts a minimum line width/spacing of 5/5 mil (0.127mm/0.127mm) and a minimum aperture of 0.2mm, enabling dense component placement and fine-pitch connections for complex designs.

Durable Surface Treatment: Chemical gold surface treatment enhances corrosion resistance, solderability, and long-term reliability—critical for harsh automotive and industrial environments.

Applications

This PCB excels in scenarios requiring compactness, durability, and complex form factors:

Industrial Instruments: Ideal for test equipment, measurement devices, and control systems where space efficiency and vibration resistance are vital.

Automotive Electronics: Suited for in-vehicle sensors, infotainment systems, and powertrain components that need flexible routing in tight engine bays or cabin spaces.
