0.2mm Thick Flexible PCB High and Low Temperature Resistance High Integration

♦ What is Flexible PCB

​​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.

♦ Advantages of FPC

• • ​​Signal stability: reduce transmission interference and ensure high-speed data transmission.

  • ​​High integration: dense arrangement of circuits and components, integrated functions.

  • ​​Flexible design: support special-shaped layout and shorten the development cycle.

  • ​​Cost controllable: reduce assembly process and material consumption.

  • ​​Environmental adaptability: high and low temperature resistance, vibration resistance, and electromagnetic interference resistance.

♦ Difficulties in Flexible PCB Manufacturing

• • ​​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.

♦ Applications of Flexible PCB

• • ​​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).
