Circuit board PCB processing belongs to the OEM customers OEM products, different customers order different products, few shared products, on the other hand, for quality considerations, some customers may also specify the use of a certain manufacturer’s substrate, or ink, etc., in order to achieve its quality and cost control requirements, so the PCB processing there are variable prices.
PCB price is composed of the following factors:
First, the PCB itself is different in difficulty caused by the diversity of prices
Even if the material is the same, the same process, but the PCB itself is different in difficulty will result in different costs. Such as two kinds of circuit boards have 1000 holes, a board aperture are greater than 0.6mm and another board aperture are less than 0.6mm will form different drilling costs; such as two kinds of circuit boards are the same, but the width of the line spacing is different, one are greater than 0.2mm, one are less than 0.2mm, will also result in different production costs, because of the difficulty of the board’s high scrapping rate is bound to increase the cost, and thus cause price diversity. In turn, resulting in price diversity.
Second, different customer requirements will also cause different prices
Customer requirements of the high and low will directly affect the board factory’s yield, such as a board according to IPC-A-600E, class1 requirements have a 98% pass rate, but according to class3 requirements may only be 90% pass rate, resulting in different board factory costs, and ultimately lead to the price of the product varied.
Third, different materials used in PCB caused by the diversity of prices
Ordinary double-sided board, for example, the board material generally FR-4, CEM-3, etc., the board thickness from 0.6mm to 3.0mm, copper thickness from 1Oz to 3 Oz different, all of which in the board material on a huge price difference; in the soldermask ink, ordinary thermosetting oil and photographic green oil there is a certain price difference, and thus the different materials caused by the diversity of prices.
Fourth, the PCB used in different production processes resulting in price diversity
Different production processes will result in different costs. Such as gold-plated boards and tin-sprayed boards, the production of the shape of the gong (milling) boards and beer (punching) boards, silk-screened lines with dry film lines and so on will form a different cost, resulting in price diversity.
Fifth, the price difference caused by different payment methods
Currently PCB board manufacturers will generally adjust the PCB price according to the different payment methods, ranging from 5% -10%, thus also causing price differences.
Sixth, the price diversity caused by different regions
At present, the domestic geographically speaking, from south to north, the price is increasing trend, there are some differences in prices in different regions, thus different regions also caused by the diversity of prices how to calculate the PCB offer!
1, the cost of the board (different board costs are different)
2, drilling costs (the number of holes and hole size affects the cost of drilling)
3, process costs (the board’s different process requirements lead to different process difficulties, so the price will be different)
4, artificial power and water plus management costs (this cost depends on the cost control of the various factories, relatively speaking, Taiwan-funded factories on the low multi-country) The basic composition of these, as for the price of raw materials, now basically stabilized, the possibility of price increases is not very likely.
Seven, PCB manufacturers caused by different price diversity
Even if the same product, but because of different manufacturers of process equipment, different levels of technology, but also the formation of different costs, many manufacturers like to produce gold-plated boards, because the process is simple, low-cost, but there are also some manufacturers to produce gold-plated boards, that is, the end-of-life rise, resulting in increased costs, so they prefer to produce tin spray boards, and thus their tin spray board offer instead of lower than the gold-plated boards.
Eight, PCB circuit board production of other factors
1, to see the line above the PCB, such as line density line fine (in 4/4mm) the following words, the price will be another calculation
2, there is a board with BGA, then the cost will rise relatively, some places are BGA another calculation of how much money a. 3, it depends on what surface treatment.
3, to see what surface treatment process, we commonly have: spray lead tin (hot air leveling), OSP (environmental protection board), spray pure tin, tin, silver, gold, etc., of course, the surface process is different, the price will be different.
4, but also look at the process standards; we commonly used: IPC2 level, but there are customer requirements will be higher, (such as the Japanese capital) we are common: IPC2, IPC3, enterprise standard, military standard, etc., of course, the higher the standard, the higher the price will be.
Nine, as far as the plate is concerned: the main impact on the price of the following points:
1, plate material: FR-4, CEM-3, this is our common double-sided and multi-layer plate, his price is also related to the plate thickness and the board in the middle of the copper platinum thickness, and FR-I, CEM-1 these are our common single and the material of the board, and the price of this material than the above double-sided, multi-layer plate is a big difference.
2, is the thickness of the plate, the thickness of our common is: 0.4, 0.6, 0.8, 1.0, 1.2, 1.5, 1.6, 2.0, 2.4, 3.0, 3.4, and the thickness of our regular plate price difference is not very big.
3, is the copper-platinum thickness will affect the price, copper-platinum thickness is generally divided into: 18 (2/1oz), 35 (1oz) 70 (2oz), 105 (3oz), 140 (4oz) and so on.
4, the supplier of raw materials, we are common and commonly used to: Sang Yi ＼ Kingboard ＼ International and other process costs.
PCB industry to sell each piece of PCB is customized, therefore, the PCB board offer needs to be the first costing, but also need to refer to the PCB computer automatic layout calculations, in the standard size of the copper-clad laminate plate on the layout of the material utilization to make a comprehensive offer.
PCB industry costing is the most special and complex of all industries, from the opening, pressure plate, forming, until the FQC, packaging, completion and warehousing, need to be based on the cost of materials invested in each process, labor costs, manufacturing costs, etc., step-by-step accounting, and then based on the order of the product number of the cumulative cost of batches. And different types of products, the standard rate of the process will be different. For some products such as blind buried holes plate, sinking gold plate, press copper seat plate, because of its process or all the special characteristics of the material, the requirements must be used in some special calculation methods. Similarly, the size of the drilling nozzle used in the drilling process also affects the cost of the product, which directly affects the calculation and evaluation of WIP cost and scrap cost.
