FPC single panel is the most basic type of FPC circuit board, with only one layer of conductive graphics layer, which is usually used for simple circuits. In SMT placement processing, the advantage of FPC single panel is its simple structure, clear placement path, easy placement and routing. However, limited by the single-layer design, its component density and complexity are low. During processing, it is necessary to pay attention to the rationality of the layout between the components, avoid pin interference, and control the welding temperature to prevent substrate deformation.
