1、 The diversity of prices due to the different materials used for FPC soft boards

Taking ordinary double-sided boards as an example, the board materials generally include PET, PI, etc. The board thickness varies from 0.0125mm to 0.10mm, and the copper thickness varies from 1/2Oz to 3Oz, all of which cause a huge price difference in the board material; There is also a certain price difference due to different brands of materials, resulting in price diversity due to differences in materials. The materials generally include PI FCCl copper foil reinforcement materials and auxiliary materials (NC pad blackening copper plating packaging materials, etc.).

2、 The different production processes used for FPC soft boards result in price diversity

Different production processes can result in different costs. For example, the precision of the production of gold-plated plates and tin spray plates, as well as the use of silk screen and dry film circuits, will result in different costs, leading to price diversity.

3、 The price diversity caused by the different difficulty levels of FPC soft boards themselves

Even if the materials and processes are the same, the difficulty of the FPC soft board 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 0.15mm, and the other is less than 0.15mm, 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.
