We must know the price of flexible FPC first know what is an FPC flexible circuit board. The FPC is a highly reliability and flexible flexible circuit board made of polyimide or polyester film, with high wiring density, light weight, thin thickness, and bending. Understanding what is the FPC flexible circuit board, we can come to the price of flexible FPC proofing.  
FPC procedures:  
1. The outer frame (clamping edge) of the circuit board puzzle should be closed-loop design to ensure that the FPC puzzle is fixed in the clamp.  
2, the outer cassette and the internal board, the connection between the sheets and the small plates cannot have large devices or extended devices, and the edges of the components and the FPC board should remain larger than 0.5 mm space, To ensure that the cutting tool is operating normally.  
3, four positioning holes in the four-frame frame of the puzzle, the aperture 4mm ± 0.01mm; the intensity of the hole should be moderate, ensuring that it does not break during the upper and lower plates; the aperture and position accuracy are high, the hole wall is smooth without burr .  
4. Each small plate in the board is at least three positioning holes, 3 ≤ aperture ≤ 6 mm, and wiring or patches are not allowed within 1mm edge positioning holes.  
Price calculation method of fpc flexible circuit board:  
1. According to the size of the size, the production chair will give the number of flexible circuit boards according to different FPC flexible circuit boards, and customers only need to convert the size of the FPC flexible circuit board to rice and multiply the unit price per square meter. The unit price of the circuit board to be produced can be obtained. This calculation method is very applicable to the FPC flexible circuit board of ordinary processes.  
2. According to the cost refined calculation price, because the raw materials of the FPC flexible circuit board are coated copper, the production of copper-clad plates set some fixed sizes to sell in the market, and the production chair failed according to the materials, layers of the circuit board to produce, the number of layers, The process, quantity and other parameters calculate the copper use of the FPC flexible circuit board to calculate the material cost.
