How much is a PCB circuit board, and what are the pricing methods for a PCB circuit board? According to the design of the PCB circuit board, the price will vary depending on the material of the PCB, the number of layers of the PCB, the size of the PCB, the quantity of each production, the production process, the smallest line width and line spacing, the smallest aperture and the number of holes, special Process and other requirements to determine. At present, there are mainly the following ways to calculate prices in the industry:

1, calculate the price by size (applicable for sample small batches)

The manufacturer will give the unit price per square centimeter according to the number of PCB layers and different processes. Customers only need to change the size of the PCB into centimeters and then multiply by the unit price per square centimeter to get the unit price of the PCB to be produced. The calculation method is very suitable for ordinary PCBs, which is convenient for manufacturers and buyers. The following is an example:

For example, a manufacturer's pricing for single panel, FR-4 material, 10-20 square meters of orders, the unit price is 0.04 yuan / square centimeter, at this time, if the buyer's PCB size is 10*10CM, the production quantity is 1000-2000 pieces, Just meet this standard, the unit price is equal to 10*10*0.04=4 yuan a piece.

2, calculate the price based on the cost (applicable for large quantities)

Because the raw material of the PCB circuit board is copper clad laminate, the factory that produces the copper clad laminate has set some fixed sizes for sale in the market, the common ones are 915MM*1220MM(36"*48");940MM*1245MM(37"*49") ;1020MM*1220MM(40"*48");1067mm*1220mm(42"*48");1042MM*1245MM(41"49");1093MM*1245MM(43"*49"); The manufacturer will produce according to The material, number of layers, process, quantity and other parameters of the circuit board calculate the utilization rate of the copper clad laminate of this batch of circuit boards, so as to calculate the material cost. For example, you produce a 100*100MM circuit board. In order to improve production efficiency, He may put together 100*4 and 100*5 large boards for production. Among them, they also need to add some spacing and board edges to facilitate production. Generally, the spacing of the gongs is 2MM, and the edges are 8-20MM. Then the large plate formed is cut in the size of the raw material. If it is just cut, there is no extra plate, which is the maximum utilization rate. Calculating the utilization is only one of the steps, and the drilling fee is also calculated to see how much Each hole, how big is the smallest hole, how many holes are in a large board, and calculate the cost of electroplating copper and the cost of each small process according to the wiring in the board, and finally add the average labor cost and loss of each company Rates, profit margins, marketing expenses, and finally divide this total cost by how many small boards can be produced in a large piece of raw material to get the unit price of small boards. This process is very complicated and requires someone to do it. Generally, quotations are required. More than a few hours.

Since the price of PCB is affected by many factors, ordinary buyers don't understand the supplier's quotation process. It often takes a long time to get a price, wasting a lot of manpower and material resources, and also because they want to understand a PCB. Price, the personal contact information is handed over to the factory, which brings subsequent continuous sales and harassment. At present, many companies have begun to build a PCB pricing program on their own websites, and through some rules, let customers freely calculate prices. For those who don’t understand PCB people can also easily calculate the price of PCB.
