1. Calculating prices by size, manufacturers will provide unit prices per square meter for different FPC flexible circuit board layers and processes. Customers only need to convert the size of the FPC flexible circuit board into meters and multiply it by the unit price per square meter to obtain the unit price of the circuit board to be produced. This calculation method is very suitable for ordinary FPC flexible circuit boards.

2. Calculate the price based on cost refinement, as the raw material of FPC flexible circuit boards is copper clad plates. The factory that produces copper clad plates has fixed sizes for sale in the market. The manufacturer will calculate the utilization rate of copper clad plates for this batch of FPC flexible circuit boards based on the parameters such as the material, layer number, process, and quantity of the circuit boards to be produced, and thus calculate the material cost.
