As modern electronics become more compact, lightweight, and complex, Flexible Printed Circuit Boards (FPCBs) Market Size are revolutionizing circuit design across industries. Unlike traditional rigid boards, FPCBs are bendable, foldable, and twistable, enabling electronic components to be placed in tight, dynamic spaces—making them indispensable in smartphones, wearables, medical devices, automotive electronics, and more.

What is a Flexible Printed Circuit Board?

A Flexible PCB is a patterned arrangement of conductive materials on a flexible insulating substrate, typically made from polyimide or polyester films. These circuits can conform to 3D shapes and withstand mechanical stress, offering high design versatility and reliability.

Types of Flexible PCBs
