Because FPC soft board can bend, fold or repeatedly move in many ways, compared with ordinary hard board (pcb), it has the advantages of light, thin, flexible, and so on. Its application is more and more extensive, and its price has also attracted people's attention. What are the factors that affect the price of FPC soft board? Let's talk about it in detail in the following section.

Factors affecting the price of FPC soft board

1. The diversity of prices due to different materials used

Take the ordinary double-sided plate as an example, the sheet materials generally include PET, PI, etc. The sheet thickness varies from 0.0125 mm to 0.10 mm, and the copper thickness varies from 1/2 oz to 3 oz, all of which cause a huge price difference in sheet materials; Different brands of materials also have a certain price difference, so different materials lead to price diversity. Materials generally include PI FCCl copper foil reinforcement materials and auxiliary materials (NC base plate blackened copper plating packaging materials, etc.).

2. Different production processes lead to diversity of prices

Different production processes will cause different costs. For example, gold-plated plate and tin-sprayed plate, the accuracy of the shape, the use of screen printing circuit and dry film circuit will form different costs, resulting in the diversity of prices.

3. Price diversity caused by different difficulties

Even if the materials are the same and the process is the same, the different difficulty of FPC soft board itself will cause different costs. For example, if there are 1000 holes on both circuit boards, the hole diameter of one board is greater than 0.6mm and the hole diameter of the other board is less than 0.6mm, different drilling costs will be formed; For example, the other two types of circuit boards are the same, but the line width and line spacing are different, one is greater than 0.15 mm, and the other is less than 0.15 mm, which will also cause different production costs. Because of the high scrap rate of difficult boards, the cost will inevitably increase, which will lead to price diversity.

4. Different customer requirements will also lead to different prices

The level of customer requirements will directly affect the finished product rate of the board factory. For example, a kind of board is required to have a 98% pass rate according to IPC-A-6013, class 1, but may only have a 90% pass rate according to class 3, resulting in different costs of the board factory, and finally lead to variable product prices.

5. Price diversity caused by different manufacturers

Even for the same product, different fpc manufacturers will have different costs because of their different process equipment and technical level. At present, many fpc manufacturers like to produce gold-plated plates because of their simple process and low cost. However, some fpc manufacturers produce gold-plated plates, and the scrap will rise, resulting in higher costs. Therefore, they prefer to produce tin-plated plates or tin-plated plates, so their price of tin-plated plates is lower than that of gold-plated plates.

6. Price difference caused by different payment methods

At present, FPC softboard manufacturers generally adjust the price of FPC softboard according to the different payment methods, ranging from 5% to 10%, which also leads to price differences.

7. Regional differences lead to price diversity

At present, in terms of geographical location in China, prices are increasing from south to north, and there are certain differences in prices in different regions. Therefore, regional differences also lead to price diversity.
