A flexible PCB (Printed Circuit Board) is a type of circuit board made from flexible substrates, widely used in thin film switch products. This type of circuit board has high flexibility and can be bent, folded, or even curled, allowing it to adapt to various shapes and space requirements. Board layer: double-sided board Line width: 0.3mm Line spacing: 0.3mm Aperture: 0.2mm Surface treatment: immersion gold Color: Yellow application area 1.
