                          What factors affect the unit price of FPC soft board

                          FPC soft board is made of polyester film or polyester imine, light and thin, high density, high flexibility, bendable and foldable, and has advantages that other types of circuit boards do not have. Compared with the traditional interconnection technology, the FPC soft board can withstand millions of bending times, is easy to install, and has good heat dissipation.

                          So, what factors affect the price of FPC?

                          1. The different materials used in FPC soft boards result in different prices

                          For example, ordinary double-sided flexible boards, the sheet materials generally include PI, PET, etc., the thickness of the board varies from 0.0125mm to 0.10mm, and the thickness of copper varies from 1/3oz to 3oz. All these have caused a big price difference. There is also a certain price difference between different material manufacturers, that is, different brands. This is the price diversity of the selection of materials. The material also contains steel sheet, FR4, PIFCCI copper foil reinforcement material and auxiliary materials.

                          Second, the process used in the flexible circuit board does not need to cause a different price

                          Different production processes also cause different costs. For example, if we use Immersion Gold, Immersion Tin, or OSP, which requires the accuracy of the shape, and the use of wet film lines or dry film lines, etc., different costs will result, resulting in different prices.

                          Third, the different technical difficulties of the flexible circuit board itself cause different prices

                          In the case of the same requirements and processes, if our flexible circuit board itself has different design difficulties, it will also cause different costs. For example, one of the two types of circuit boards has over-standard holes on the board, and the other is within the conventional range, so the cost of drilling is also different. Unfinished circuits, such as one with a line width greater than 0.1MM, and the other If it is less than 0.1mm, this will also cause a price difference, because the scrap rate of difficult boards is high, and the cost will inevitably increase, resulting in different prices.

                          Fourth, the customer requirements are different, the price is also different

                          The level of customer requirements will directly affect the production rate of the board factory. For example, a board according to IPC-A-6013, class1 requires 98% pass rate, but according to class3 requirements, it may only have a pass rate of 90%, resulting in different costs for the board factory. , And finally lead to volatile product prices.

                          Fifth, the price diversity caused by different flexible circuit board manufacturers

                          Even for the same product, because different manufacturers have different process equipment and technical levels, they will have different costs. Nowadays, many manufacturers like to produce gold-plated plates because of the simple process and low cost. However, some manufacturers produce gold-plated plates, and the scrap will increase. As a result of increased costs, they would rather produce tin-sprayed panels or tin-plated panels, so their quotation for tin-sprayed panels is lower than that of gold-plated panels.

                          Six, price differences caused by different payment methods

                          At present, flexible circuit board manufacturers generally adjust the price of flexible circuit boards according to different payment methods, ranging from 5% to 10%, which also causes price differences.

                           7. Different regions cause price diversity

                          At present, in terms of geographic location in China, prices are increasing from south to north, and there are certain differences in prices in different regions. Therefore, different regions also result in price diversification.

                          Eight, different electroplating methods cause different prices

                          Partial electroplating is about 15% of full electroplating.

                           Nine, the surface treatment method of the golden finger part

                           The difference between gold plating and tin plating is about 5%

                          Ten: The defect rate in the FPC production process also determines the unit price of FPC

                          Eleven: The cost of SMT on behalf of customers and the level of non-performing rate also determine the unit price of FPC
