The price of PCB is composed of several factors

①The materials used by different diversity price

In ordinary double sheet plate as an example, general FR-4, CEM-3, thickness from 0.6mm to 3.0mm ranging from 3 to Oz thick copper integrant Oz different, all of these will cause a huge price difference in sheet; the solder resist ink, photosensitive thermosetting ordinary oil and there are green a fixed price difference, thus the materials caused by different variety of prices.

②The production process by PCB caused by different price diversity

Different production processes will result in different cost. Such as gold plate and tin spraying plate shape, making the gong (milling) board and beer (red) plate, the printing line and dry film line will form different costs, resulting in the diversity of the price.

③Due to the diversity of different price PCB difficulty

Even if the same material, the same process, but PCB itself different difficulty but also have different costs. Such as two kinds of circuit board has 1000 holes, one plate aperture is greater than 0.6mm and the other plate aperture is less than 0.6mm will form the drilling cost is different; such as the other two kinds of circuit boards are the same, but from a different line width, were more than 0.2mm, a less than 0.2mm, but also have different production costs, because of the difficulty of the retirement rate is higher, the inevitable costs increase, causing the price of diversity.

④Different customer requirements will result in different price

Customer requirements will directly affect the yield of plate plant, such as a plate by IPC-A-600E, the Class1 requires a 98% pass rate, but according to the requirements of class3 may pass rate of only 90%, resulting in different factory cost, finally lead to price change.

⑤Due to the diversity of different manufacturers PCB price

Even the same kind of products, but because of the different manufacturers of process equipment, technical level is different, will form different cost, nowadays many manufacturers love gold plate production, because the process is simple, low cost, but there are also some manufacturers of gold plate, which is caused by rising scrap, raising the cost of production, so they prefer HASL. Thus they HASL offer rather than gold plate.

⑥The price difference caused by different ways of payment

The PCB factory will generally according to the different methods of payment and price adjustment of PCB, amplitude of 5%-10% range, thus causing the price difference.

⑦Regional diversity caused by different price

At present, geographically speaking, from the south to the north, prices showed increasing trend of prices in different regions is different, so different regions also resulted in the diversity of the price.
