7 factors affecting the price of PCB board [Detailed explanation]

7 factors affecting the prICe of PCB board [DetaiLED explanation]


At present, the PCB copying MARKet is not open, and the cost of copying a PCB varies greatly from one manufacturer to another. What is the quotation standard for PCB copy? PCB copy price is composed of the following factors: material, production process, difficulty, customer requirements, copy company, payment method and region.

1、 Different materials used for PCB board reading result in price diversity

Taking ordinary double-sided copy board as an example, the sheet materials generally include fr-4, cem-3, etc. The thickness of the sheet varies from 0.6mm to 3.0mm, and the copper thickness ranges from&; frac12; Oz to 3 Oz are different, all of which cause huge price difference in sheet metal; In terms of solder resist ink, there is a certain price difference between common thermosetting oil and photosensitive green oil, so the difference of materials results in the diversity of prices.

2、 Different production processes used for PCB copying result in price diversity

Different production processes will result in different costs. For example, gold plating plate and tin spraying plate, gongs (milling) plate and beer (punching) plate with shape, silk screen circuit and dry film circuit will all form different costs, resulting in price diversity.

3、 Price diversity caused by different difficulties of PCB copying

Even if the materials are the same and the process is the same, the different difficulty of PCB itself will result in different costs. For example, if there are 1000 holes on both kinds of circuit boards, the drilling cost will be different if the hole diameter of one board is greater than 0.6 mm and the hole diameter of the other board is less than 0.6 mm; If the other two types of circuit boards are the same, but the line width and line spacing are different, one is greater than 0.2mm, and the other is less than 0.2mm, it will also cause different production costs. Because the boards with great difficulty have a higher scrap rate, the cost will inevitably increase, which will lead to price diversity.

4、 Different customer requirements will lead to different prices

The level of customer requirements will directly affect the yield of the board factory. For example, according to the requirements of IPC-a-600e and class1, the yield of a board is 98%, but according to the requirements of class3, the yield may be only 90%. This will result in different costs for the board factory, and ultimately lead to variable product prices.

5、 Price diversity caused by different PCB copying companies

Even for the same product, different manufacturers have different costs because of their different process equipment and technical levels. Nowadays, many manufacturers like to produce gold plated plates because of their SIMple process and low cost. However, some manufacturers produce gold plated plates, and the cost increases as they are scrapped. Therefore, they prefer to produce tin spraying plates, so their tin spraying plate quotation is lower than that of gold plated plates.

6、 Price difference caused by different payment methods

At present, board copying companies generally adjust PCB prices according to different payment methods, ranging from 5% to 10%, which also leads to price differences.

7、 Different regions result in price diversity

At present, in terms of geographical location in China, prices are increasing from south to north. Prices in different regions are different to some extent, so different regions also cause price diversity.

From the above discussion, it is not difficult to see that the diversity of PCB copy price has its inherent inevitable factors.
