Understanding FPCs and Their Unique Features

What Is an FPC?

A flexible printed circuit (FPC) is a special type of circuit. It can bend and twist without breaking. Unlike hard boards, FPCs are made with thin, bendable materials like polyimide or polyester film. This makes them fit into small spaces and odd shapes. They are perfect for modern gadgets.

FPCs are made using advanced methods like electrohydrodynamic (EHD) printing. This process creates very tiny features, even smaller than the nozzle size. It works on micro and submicron levels. EHD printing uses many materials, like thick polymers and soft metals. By adjusting voltage and timing, makers get clear and steady results. For example, nano-silver circuits can be printed on flexible PET sheets. This shows how useful FPCs are for new technology.

How FPCs Differ from Traditional Circuit Boards

FPCs are different from regular circuit boards because of their special features. Both are important for electronics, but they are built and work differently. The table below shows their main differences:
