PCB Technical - The composition of the price of flexible circuit boards

PCB factory purchasers have been confused by the changeable price of flexible circuit boards. Even some people with years of flexible circuit board procurement experience may not fully understand the reasons for this. In fact, the price of flexible circuit boards is caused by the following multiple factors consist of:

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

Take the ordinary double-sided board as an example. The sheet materials generally include PET, PI, etc. The thickness of the sheet varies from 0.0125mm to 0.10mm, and the copper thickness varies from z to 3 Oz. All of these cause a huge difference in the sheet material. Price difference; there is also a certain price difference between different brands of materials, so the difference in materials causes the diversity of prices.

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

Different production processes will cause different costs. Such as gold-plated boards and tin-sprayed boards, the precision of the shape of the production, the use of silk-screened lines and dry film lines, etc. will cause different costs, resulting in a variety of prices.

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

Even if the material is the same and the process is the same, the different difficulty of the flexible circuit board itself will cause different costs. For example, there are 1000 holes on two kinds of circuit boards, and the hole diameter of one board is larger than 0.6mm and the hole diameter of the other board is smaller than 0.6mm, which will result in different drilling costs; for example, the two kinds of circuit boards are the same, but the line width and line spacing Different, one type is greater than 0.15mm, and one type is less than 0.15mm, which will also cause different production costs, because the difficult board has a higher scrap rate, which will inevitably increase the cost, and thus cause the price diversity.

Fourth, different customer requirements will also cause different prices

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 a 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.

Five, 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 prefer to 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.

Seven. Different regions cause price diversity

At present, in terms of geographic location in China, the price is increasing from south to north. There are certain differences in prices in different regions. Therefore, different regions also cause price diversification.

Through the above discussion, it is not difficult to see that the price diversity of flexible circuit boards has its inherent inevitable factors. This column can only provide a rough price range for reference. Of course, the specific price is still in direct contact with the PCB manufacturer.
