Factors that affect PCB production price changes

PCB processing belongs to OEM customer OEM products, not the same customer customized products are different, few shared products, on the other hand, out of quality thinking, some customers may also specify the use of a manufacturer's substrate, or ink, in order to achieve its quality and cost control requirements, so there is a variable price PCB processing.

PCB price is composed of the following factors:

First, PCB materials are not the same, leading to the diversity of prices.

Take the usual double panel as an example, the plate generally has FR-4, CEM-3, plate thickness from 0.6mm to 3.0mm is not equal to, copper thickness from 1Oz to 3 Oz is not the same, all these in a plate led to a great price difference; In welding ink, there is a certain price difference between ordinary thermosetting oil and photosensitive green oil, so the different materials lead to the diversity of prices.

Second, PCB board think is appropriate and the use of production technology is not the same, resulting in the diversity of prices.

Different production processes will lead to different costs. Such as gold-plated plate and tin plate, manufacturing appearance of gong (milling) plate and beer (punching) plate, think appropriate and the use of silk screen line and dry film line will form a different cost, resulting in the diversity of price.

Third, the price diversity caused by the different degree of difficulty of PCB itself.

Although the material is the same, the process is the same, but the PCB itself is not the same difficulty will lead to different costs. If there are 1000 holes on both types of circuit boards, the hole diameter of one board is greater than 0.6mm and that of the other board is less than 0.6mm, the drilling cost will be different. If the other two kinds of circuit boards are the same, but the line width and line distance are not the same, one is greater than 0.2mm, one is less than 0.2mm, it will also lead to different production capital, due to the difficulty of the blackboard scrap rate is higher, the cost will increase, continue to lead to the diversity of price.

Four, different customer requirements will lead to different prices.

The level of customer requirements will directly affect the finished product rate of the plate factory, such as a plate according to IPC-A-600E, class1

It is required to meet the standard rate of 98 percent, but according to the class3 requirement may only meet the standard rate of 90 percent, which leads to the different costs of the board factory, and the final result is the variable product price.

Five. Price diversity caused by different PCB manufacturers.

Even if the same product, but because different manufacturers process equipment, technical level is not the same, will also form different costs, many manufacturers like to produce gold-plated plate, because of the simple process, low cost, but also a small number of manufacturers produce gold-plated plate, abandoned is rising, resulting in cost growth, so they would rather produce tin-spray plate, Therefore, their spray tin blackboard offer is lower than the gold plate.

Six,Price difference caused by different forms of payment.

Up to now,circuit board manufacturers generally adjust PCB prices according to different forms of payment, with a range of 5%-10%, which also leads to the difference in prices.

Seven, the range of different regions lead to the diversity of prices.

Up to now, from the geographical position of the country, from the north to the south, the price of the increase trend, not the same as the regional range of price has a certain difference, so the regional range is not the same, also led to the diversity of the price how to calculate PCB quotation!

1. Board cost (different board cost is different)

2. Drilling cost (the number of holes and the volume of the aperture reflect the drilling cost)

3, the cost of the process (different process requirements of wrenches cause different degrees of difficulty in the process, and even the price will be different)

4, artificial water and electricity plus management costs (this cost depends on the cost of various factories, relatively speaking, Taiwan-funded factories on the low multinational) basic structure performance of these, as for the price of raw materials, now tend to be stable, the possibility of rising half.

Eight: in terms of board material: the price is mainly affected by the following points:

1, board material: FR-4, CEM-3, this is our common double-sided and multi-layer board, its price is also related to plate thickness and plate mid-waist copper platinum thickness, and FR-I, CEM-1 these are our common single and plate material, and the price of this material is also higher than double-sided, multi-layer board difference is very large.

2, is the thickness of the board, its thickness is 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 our common plate thickness price difference is not often large.

3, is the thickness of copper platinum will affect the price, copper platinum thickness is generally divided into: 18 (2/1OZ), 35 (1OZ) 70 (2OZ), 105 (3OZ), 140 (4OZ), etc

Nine: PCB circuit board manufacturing other factors

1, to see the PCB above the line, such as the line is dense and thin (in 4/4mm), the price will be calculated separately

2. There is a BGA on the board, so the cost will rise relatively. In some places, BGA counts some money in addition.

3, to see what is the appearance of the disposal process, we commonly have: spray lead tin (hot air leveling), OSP (environmental protection board), spray pure tin, tin, silver, gold and so on, of course, the appearance of the process is not the same, the price will be different.

4, also look at the process standard; We commonly used is: IPC2 level, but some customers will be higher requirements, (than such as Japanese) our common are: IPC2, IPC3, enterprise standard, military standard and so on, of course, the higher the standard, the higher the price will be.

Every PCB circuit board sold in the industry is customized, because of this, the quotation of PCB circuit board needs to be advanced line cost calculation, but also needs to refer to the PCB circuit board computer semi-automatic layout calculation, in the standard size of copper clad plate typesiting material utilization rate to make a comprehensive quotation.

The cost calculation of PCB circuit board is the most especially and the most complex in the whole industry. From opening material, pressing plate, forming, until FQC, packaging, completion and storage, the cost of material, labor and production of each process input is calculated step by step, and then the total cost of batch according to the product number of the order. Moreover, different types of products, the standard rate of the process will be different. For some products such as blind hole plate, gold plate, copper plate, because of its process or the special nature of all materials, it is necessary to consider this appropriate and use a special calculation method. Similarly, the volume of drill nozzle used in the drilling process will also affect the cost of the product, which directly affects the calculation and evaluation of WIP cost and waste cost.
