PCB Circuit board price and cost standards

PCB Circuit board price and cost standards

Depending on the design of the circuit board, the price will vary due to the material of the circuit board, the number of layers of the circuit board, the size of the circuit board, the number of each production, the production process, the smallest line width and spacing, the smallest aperture and the number of holes , Special technology and other requirements to determine. There are several ways to calculate prices in the industry:

1.Calculate price by size (applicable to small batches of samples)

The manufacturer will give the unit price per square centimeter according to the different layers of the circuit board and different processes. The customer only needs to change the size of the circuit board to cm and then multiply 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 the circuit board of common technology, which is convenient for both manufacturers and buyers. The following are examples:

For example, the price of a single panel, FR-4 material, and an order of 10-20 square meters is priced at 0.04 yuan per square centimeter. If the size of the circuit board of the buyer is 10 * 10CM, the quantity produced is 1000-2000. Block, just meet this standard, the unit price is equal to 10 * 10 * 0.04 = 4 yuan a piece.

2.Fine calculation by cost (for large quantities)

Because the raw material of the circuit board is copper clad laminates, the factories that produce the copper clad laminates have 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 calculate the copper clad utilization of this batch of circuit boards according to the circuit board materials, layers, processes, quantities and other parameters to be produced, so as to calculate the material cost. For example, you produce a 100 * 100MM circuit board In order to improve the production efficiency, the factory may produce large boards of 100 * 4 and 100 * 5 for production. Among them, they also need to add some spacing and board edges to facilitate production. Generally, the gap of the gong board is 2MM. Leave 8-20MM on the edge of the board, and then cut the large board in the size of the raw material. If it happens to be cut here, there is no extra board, which means that the utilization rate is maximized. Calculating the utilization is only one step, and it is also a drill. Hole fee, see how many holes there are, how small the smallest hole is, how many holes a large board has, and the cost of each small process such as the cost of electroplated copper according to the wiring in the board, and finally add each The company's average labor cost, attrition rate, profit margin, marketing costs, and finally divide this total cost A large number of raw materials can be produced in small plates, small plates draw unit price. This process is very complex, the need for someone to do, usually have to offer more than a few hours.

3.Online meter

Because the price of circuit boards is affected by many factors, ordinary buyers do not understand the process of quoting suppliers. Often it takes a long time to get a price, a lot of manpower and material resources are wasted, and it is because they want to understand a circuit. The price of the board, the personal contact information is handed over to the factory to bring follow-up continuous sales harassment. Many companies have begun to build a circuit board pricing program on their website, allowing customers to calculate the price freely through some rules. People who know PCB can easily calculate the price of PCB.

The maximum charge for maintenance costs is not more than 30% of the original value of the electronic board. Secondly, fees are charged according to the degree of circuit board breakage, difficulty, number of parts, and the cost of parts. In special cases, increase or decrease as appropriate.
