Introduction
Depending on the design of the circuit board, the price will vary depending on the material of the circuit board, the number of layers of the circuit board, the size of the circuit board, the quantity of each production, the production process, the minimum line width and line spacing, the minimum hole diameter and the number of holes , special process and other requirements to decide. There are mainly the following ways to calculate the price in the industry:
1. Calculate the price by size (applicable for small batches of samples)
The manufacturer will give the unit price per square centimeter according to different circuit board layers and different processes. Customers only need to convert the size of the circuit board into centimeters and multiply by the unit price per square centimeter to get the unit price of the circuit board to be produced. .This calculation method is very suitable for circuit boards of ordinary technology, which is convenient for both manufacturers and buyers. The following are examples:
For example, if a manufacturer prices a single panel, FR-4 material, and an order of 10-20 square meters, the unit price is 0.04 yuan/square centimeter. At this time, if the buyer’s circuit board size is 10*10CM, the production quantity is 1000-2000 piece, just meets this standard, and the unit price is equal to 10*10*0.04=4 yuan a piece.
2. Calculate the price according to the cost refinement (applicable for large quantities)
Because the raw material of the circuit board is copper clad laminate, the factory that produces 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 base on the circuit to be produced The material, layer number, process, quantity and other parameters of the board are used to calculate the utilization rate of the copper clad laminate of this batch of circuit boards, so as to calculate the material cost. For example, if you produce a 100*100MM circuit board, the factory will increase the production efficiency. It may be assembled into large boards of 100*4 and 100*5 for production. They also need to add some spacing and board edges to facilitate production. Generally, the spacing between gongs and boards is 2MM, and the board edge is 8-20MM. Then The formed large boards are cut in the dimensions of the raw material,If it is just cut here, there are no extra boards, and the utilization rate is maximized. Calculating the utilization is only one step, and the drilling fee is also calculated to see how many holes are there, how big is the smallest hole, and how many are there in a large board holes, and calculate the cost of each small process such as the cost of electroplating copper according to the wiring in the board, and finally add the average labor cost, loss rate, profit rate, and marketing cost of each company, and finally calculate the total cost Divide by the number of small boards that can be produced in a large piece of raw material to get the unit price of the small board. This process is very complicated and requires a special person to do it. Generally, the quotation takes more than several hours.
3. Online meter
Because the price of circuit boards is affected by many factors, ordinary buyers do not understand the quotation process of suppliers. It often takes a long time to get a price, which wastes a lot of manpower and material resources. The price of the circuit board, handing over the personal contact information to the factory will lead to continuous sales harassment. Many companies have begun to build a circuit board pricing program on their website, and through some rules, customers can freely calculate the price. For those who do not People who understand PCB can also easily calculate the price of PCB.
