1、 PCB copying material

　　Taking ordinary double-sided sheet metal as an example, sheet materials generally include FR-4, CEM-3, etc., with sheet thicknesses ranging from 0.6mm to 3.0mm, and copper thicknesses ranging from frac12oz to 3oz, all of which cause significant price differences in sheet metal; In terms of solder resist ink, there is also a certain price difference between ordinary thermosetting oil and photosensitive green oil.

　　2、 PCB board copying production process

　　Different production processes can result in different costs, such as gilded and tinned plates, gongs (milled) and beers (punched) plates for manufacturing shapes, and the use of silk screen and dry film circuits.

　　3、 PCB copying difficulty

　　Even if the materials and processes are the same, the difficulty of the PCB itself will result in different costs. If there are 1000 holes on both types of circuit boards, and one board has a hole diameter greater than 0.6mm and the other board has a hole diameter less than 0.6mm, different drilling costs will be formed; If the other two types of circuit boards are the same, but the line width and distance 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 difficult board has a higher scrap rate, the cost will inevitably increase, resulting in price diversity.

　　4、 PCB copying company

　　Even for the same product, different manufacturers may have different costs due to their different process equipment and technical levels. Therefore, it is necessary to carefully select qualified PCB copying companies in order to reduce the cost of copying to a certain extent.
