How to Calculate The Cost And Quotation of PCB Board (1)

First, the different materials selected for pcb boards cause the price diversity.

Let’s talk about double-sided boards. Sheet materials generally include FR-4, CEM-3, etc. The sheet thickness varies from 0.6mm to 3.0mm, and the copper thickness varies from ½Oz to 3 Oz. These different sheets cause huge costs difference. The gap, in terms of solder mask ink, there is also a certain price difference between ordinary thermosetting oil and photosensitive green oil, so the difference in materials causes the price diversity.

 

Second, the difference in the production process used by PCB causes the diversity of prices.

Different production processes will cause different costs. For example, gold-plated boards and tin-sprayed boards, the production of gongs (milling) boards and beer (punching) boards, and the use of silk-printed lines and dry film lines will all cause different costs, resulting in a variety of prices.

 

Third, the price diversity caused by the difficulty of PCB.

Even if the material is the same and the process is the same, the difficulty of the different PCB will cause different costs. If there are 1000 holes on two kinds of circuit boards, 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 are different, one is greater than 0.2mm, and the other is less than 0.2mm, 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-600E, 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.

 

Fifth, the price diversity caused by different PCB 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, when some manufacturers produce gold-plated plates, the scrap will increase, as a result of increased costs. They would rather produce tin-sprayed panels, so their quotation for tin-sprayed panels is lower than that of gold-plated panels.

 

Sixth, price differences caused by different payment methods.

At present, PCB board manufacturers generally adjust PCB prices according to different payment methods, ranging from 5% to 10%, which also causes price differences.

 

Seventh, the diversity of prices caused by regional differences.

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

1. Plate cost (different plate has different cost)

2. Drilling costs (the number of holes and the size of the aperture affect the cost of drilling)

3. Process cost (different process requirements of the board lead to different process difficulties, and even prices will vary)

4. Artificial water and electricity plus management costs (this cost depends on the cost control of each factory)

That’s all for the basic composition. As for the prices of raw materials, they have basically stabilized and the possibility of price increases is unlikely.
