High Quality Polyimide Material Flexible PCB Double Layer Flex PCB FPC

Flexible PCB (FPC), also called a "soft board" or flexible circuit, is a type of printed circuit board (PCB) made from flexible insulating materials, such as polyimide (PI) or polyester (PET), instead of rigid fiberglass (FR4). This unique construction allows FPCs to bend, fold, and twist without breaking, enabling compact, lightweight, and space-saving designs in modern electronics.

• Lightweight and portable: thin thickness and light weight, saving equipment space and weight
• Flexible and bendable: bendable and foldable, adaptable to complex structural design
• Durable: resistant to repeated bending and long service life
• Stable signal: reduce transmission interference and ensure high-speed data transmission
• High integration: dense arrangement of circuits and components, integrated functions

• Base material is fragile: PI film is thin and easy to wrinkle and crack, low-tension precision processing is required
• Micro-line is difficult to control: micron-level line width/spacing, electroplating and hole filling are prone to defects
• Strict alignment: multi-layer lamination requires high precision, and offset affects yield
• Surface sensitivity: The plating needs to balance flexibility and conductivity, and the process window is narrow
• Complex detection: internal line defects are difficult to detect, relying on expensive equipment such as X-ray

• Smartphones & Wearables (foldable screens, flexible displays)
• Laptops & Tablets (hinge connections, battery flex cables)
• Automotive Electronics (sensors, lighting, dashboard controls)
• Medical Devices (implantable electronics, diagnostic equipment)
• Aerospace & Defense (lightweight, high-reliability circuits)
