7 factors affecting the price of PCB copy board [Detailed Explanation]


At present, the PCB copy board market is not public, and the cost of copying a PCB board will vary greatly from each company. What is the standard for PCB copy board quotation? The price of PCB copy board is composed of the following factors: material, production process, difficulty, customer requirements, copy board company, payment method, and area.


1. The different materials used in PCB copy boards cause the diversity of prices
Take the ordinary double-sided copy board as an example. The sheet materials are generally fr-4, cem-3, etc., the thickness of the board varies from 0.6mm to 3.0mm, and the copper thickness varies from &;frac12;oz to 3 oz, all of which are on the board. One item of materials has caused a huge price difference; 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 has caused the price diversity.

Second, the difference in the production process used by the PCB copy board causes the price diversity
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 cause different costs, resulting in a variety of prices.


Third, the price diversity caused by the difficulty of PCB copy board itself
Even if the material is the same and the process is the same, the difficulty of the PCB 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 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 and class1 requires a 98% pass rate, but according to the class3 requirement, it may only have a pass rate of 90%, which results in different costs for the board factory. , And finally lead to volatile product prices.


Five, the price diversity caused by different PCB copy board companies
Even for the same product, because different manufacturers have different process equipment and technical levels, different costs will be formed. 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 would rather produce tin-sprayed 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, PCB companies generally adjust PCB prices according to different payment methods, ranging from 5% to 10%, which also causes price differences.


7. Different regions cause price diversity
At present, in terms of geographical location in China, prices are increasing from south to north, and 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 diversity of PCB copy board prices has its inherent inevitable factors.
