Flexible PCB are a sort of printed circuit board expected to bend and flex to get into negligible or phenomenally formed contraptions. Dissimilar to conventional inflexible PCBs, which are produced using strong materials like fiberglass, flexible PCBs use materials like polyimide or polyester that permit them to be collapsed, contorted, or folded over corners without harming the circuitry. This adaptability empowers their utilization in applications where space is restricted or where the board should adjust to a particular shape.
