First, the different materials used in flexible circuit boards cause the diversity of prices

　　Taking ordinary double panels as an example, the board material is generally PET, PI, etc., the board thickness ranges from 0.0125mm to 0.10mm, and the copper thickness ranges from 0.0125mm to 0.10mm. Oz to 3 Oz, all of which creates a huge price difference in sheet metal alone; The different brands of materials also have a certain price difference, so the different materials cause the diversity of prices.

　　Second, the different production processes used in flexible circuit boards cause the diversity of prices

　　Different production processes result in different costs. Such as gold-plated plate and tinned plate, the accuracy of the production shape, the use of silk screen lines and dry film lines will form different costs, leading to the diversity of prices.

　　Third, the price diversity caused by the different difficulty of the flexible circuit board itself

　　Even if the material is the same and the process is the same, the difficulty of the flexible circuit board itself will cause different costs. If there are 1000 holes on both types of circuit boards, the aperture of one board is greater than 0.6mm and the aperture of the other board is less than 0.6mm, different drilling costs will be formed; If the other two kinds of circuit boards are the same, but the line width and line distance are different, one is greater than 0.15mm, and one is less than 0.15mm, it will also cause different production costs, because the difficult board scrap rate is higher, the inevitable cost will increase, and then cause the diversity of prices.
