After the electronic product development project is finalized, engineers and procurement departments need to estimate the price of the entire PCBA circuit board. The simple method is to send the design BOM and GERBER files to different suppliers to obtain quotations for comparison. But the problem is that when there is a significant difference in the price of PCBA we obtain, we cannot determine the true and accurate price. Because different suppliers may substitute materials or make random estimates, which can mislead your prices. At this time, it is particularly important to self estimate the price of PCBA processing.

　　PCBA processing price mainly includes: component cost, PCB cost, SMD processing cost, and basic Gross profit of manufacturing enterprises. The cost of components can be inquired through the public Open platform (Tradegate, Datagate), and its open price can be used as a reference. For large goods above 10K, it can generally be estimated at 70% of the open price. The cost of PCB can be calculated through online platforms such as Jialichuang. The cost of SMD processing can be calculated by multiplying the number of pins of components by 0.01 yuan and the number of solder joints of plug-ins by 0.05 yuan. The Gross profit of the enterprise is basically 15%. This can quickly calculate the price of the entire PCBA.

　　In order to obtain accurate PCBA processing prices, designers need to clarify the part number of each material in the BOM file and define the design parameters of the PCB, in order to minimize misleading supplier quotations.
