A Flexible Printed Circuit (FPC) is a type of electronic circuit that is made on a flexible substrate, allowing it to bend and twist without breaking. This design is commonly used in various electronic devices, such as smartphones and tablets, where space is limited and components need to be lightweight. FPCs can connect different parts of a device while maintaining a compact form factor. FPCs are typically made from materials like polyimide or polyester, which provide durability and flexibility. They can be single-sided, double-sided, or multi-layered, depending on the complexity of the circuit. Their versatility makes them essential in modern electronics, enabling innovative designs and improved performance.
