Composition Of Flexible Circuit Board Prices
First, the materials used in flexible circuit boards
Take an ordinary double-sided board as an example, the sheet materials generally include PET, PI, etc., the sheet thickness ranges from 0.0125mm to 0.10mm, and the copper thickness varies. Oz to 3 Oz are different, all of which cause a huge price difference on the sheet; the brand of the material also has a certain price difference, so the different materials cause the price diversity.
Second, the production process used in flexible circuit boards
Different production processes will cause different costs. Such as gold-plated plate and tin-sprayed plate, the accuracy of the shape, the use of silk screen lines and dry film lines will form different costs, resulting in price diversity.
Third, the difficulty of the flexible circuit board itself
Even if the materials are the same and the process is the same, the different difficulties of the flexible circuit 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. Different, one is larger than 0.15mm, and one is smaller than 0.15mm, it will also cause different production costs, because the scrap rate of difficult boards is high, the cost will inevitably increase, which will lead to price diversity.
Fourth, customer requirements are different
The level of customer requirements will directly affect the yield of the board factory. For example, a board according to IPC-A-6013, class 1 requires a 98% pass rate, but according to class 3 requirements, it may only have a 90% pass rate, resulting in different costs for the board factory. , And finally lead to changeable product prices.
Fifth, flexible circuit board manufacturers
Even for the same product, because different manufacturers have different process equipment and technology levels, they will also have different costs. Many manufacturers nowadays like to produce gold-plated plates because of the simple process and low cost, but some manufacturers also produce gold-plated plates. As a result of the increase in cost, they would rather produce tin-plated or tin-plated plates, so their quotes for tin-plated plates are lower than gold-plated plates.
Six, payment methods are different
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
At present, in terms of geographical location in China, prices are increasing from south to north, and prices vary from region to region. Therefore, regional differences also cause price diversity.
