♦ 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.

♦ Features of Flexible PCB

• • ​​Ultra-thin and light: PI substrate, weight reduction and space saving.
  • ​​High flexibility and bending resistance: can be bent repeatedly (more than 10,000 times).
  • ​​Miniaturization: supports micron-level circuits and high-density integration of components.
  • ​​3D adaptation: fits complex shapes and reduces assembly processes.
  • ​​Stable and reliable: resistant to high and low temperatures (-40℃~+125℃), vibration and shock.

♦ Difficulties in Flexible PCB Manufacturing

• • Delicate substrate: thin and soft, easy to wrinkle and crack during processing.
  • Ultra-fine lines: micron-level line width, easy to break or connect incorrectly.
  • Difficult alignment: multiple layers are easily misaligned.
  • Difficult surface treatment: both bendable and conductive.
  • Troublesome detection: internal problems are difficult to find, and detection is expensive and time-consuming.

♦ 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).
