How much money PCB circuit boards, PCB pricing have? According to the PCB design is different, the price will be for PCB material, PCB layers, the size of PCB, each time the number of production, production process, the smallest line width line distance, the smallest aperture and the number of holes, a special process requirements to decide. At present the industry mainly has the following several ways to calculate the price:
1, according to the size calculated price for small batch sample (applicable)
Chamber of commerce according to the different layers of PCB production, the price per square centimeter different process is given, the customer only need to change the size of the PCB to cm and then multiplied by the unit price per square centimeter can be concluded that to produce the PCB unit price. This way of calculation for ordinary process of PCB is very applicable, convenient producers also permit purchaser.
The following is an example:
A single panel factory pricing, for example, FR - 4 material, order for 10-20 square metre, the unit price is 0.04 yuan/square centimeter, at this moment if the purchaser of the PCB size is 10 * 10 cm, the number of production is 1000-2000, will just fit the criteria, the unit price is equal to 10 * 10 * 0.04 = $4 a piece.
2, by elaborating calculation cost price (for large quantities of applicable)
For PCB raw material is copper clad, the production of copper clad factory set the sales in the market, some fixed size common have 915 mm * 1220 mm (36 "x 48"); 940 mm * 1245 mm (37 49 "*"); 1020 mm * 1220 mm (40 "x 48"); 1067 mm * 1220 mm (42 "x 48"); 1042 mm * 1245 mm (41 "49"); 1093 mm * 1245 mm (43 49 "*"); Production according to the chamber of commerce to the circuit boards of production material, layer number, process, the number of parameters to calculate the utilization of this batch of circuit board copper clad laminates, so as to calculate the cost of materials, for example, is in you to make a piece of the circuit boards of 100 * 100 mm, the factory in order to improve the production efficiency, he is likely to spell into 100 * 100 * 4 and 5 large plate to production, which they need to add some spacing and edge for convenient production, general gong plate spacing of 2 mm, edge 8 to 20 mm, then the formation of the large plate in the size of the raw material to cut, if just cut here, no extra plate, is to maximize utilization. Calculate the use of just one step, and drilling cost, see how many holes, the smallest hole, a large plate, how many holes according to bat in the walk line to calculate the electroplating copper cost of each process, such as the cost of the last and each company's average labor, attrition rate, profit margins, marketing expenses, finally the total cost divided by a large piece of raw materials can produce many small plate, it is concluded that the unit price of small plate. This process is very complex, needs to have someone to do, generally offer more than a few hours.
3, PCB online meter
Because the price of PCB is affected by many factors, the ordinary purchaser to supplier process also do not understand, often in order to get a price need to spend a long time, waste a great deal of manpower material resources, also because you want to know the price of a PCB, personal contact information to the factory, with the subsequent constantly harassed. There are a lot of companies start on its web site to build a PCB valuation procedure, through some of the rules, let the customer free price calculation. For people who do not understand the PCB can easily calculate the price of the PCB.
