Flexible Printed Circuit Board
Flexible Printed Circuit Board in Electronics Manufacturing
A Flexible Printed Circuit Board (FPC) is a special type of PCB (Printed Circuit Board) designed to bend or flex during use. Unlike traditional rigid PCBs, FPCs are made of flexible materials like polyimide, allowing them to fit into tight or irregular spaces.
This guide explains what flexible PCBs are, how they work, and why they are crucial in modern electronics.
What is a Flexible Printed Circuit Board (FPC)?
Question: What does an FPC do?
Answer:
A Flexible Printed Circuit Board (FPC) is a thin and lightweight circuit board that can bend without breaking. It connects electronic components while accommodating designs that require flexibility or compactness.
FPCs are commonly used in foldable devices, wearable electronics, and medical devices, where space-saving and flexibility are key.
