Hard board: PCB, commonly used as motherboard, can not be bent.
Hard Board: Printed Circuit Board (PCB); Flexible Printed Circuit Board: FPC or FPCB. Rigid Rigid Board: RFPC or RFPCB (Rigid Flex Printed Circuit Board), as the name implies, is a new type of wire Board with both hard Board and soft Board characteristics. The hard part, like the PCB board, has a certain thickness and strength to mount electronic components and withstand mechanical forces, while the soft part is usually used to achieve three-dimensional installation. The use of the soft board allows the whole hard and soft board to bend locally.
Soft board: FPC, also known as flexible circuit board, can be bent.
FlexiblePrintedCircuit board (FPC), also known as flexible circuit board, flexible circuit board, its light weight, thin thickness, free bending and folding and other excellent characteristics are favored, but the domestic quality inspection of FPC also mainly rely on manual visual inspection, high cost and low efficiency. With the rapid development of electronic industry, circuit board design tends to be more and more high precision, high density, the traditional manual detection method can not meet the production demand, FPC defect automatic detection has become an inevitable trend of industrial development.
