PCB processing belongs to the OEM customer's OEM products. Different customers order different products, and there are few shared products. On the other hand, some customers may specify the use of a manufacturer's substrate for quality considerations. Ink and so on, in order to achieve its quality and cost control requirements, so PCB processing prices are changeable.
What are the factors that affect the price of PCB processing? Basically consists of the following factors:
First, the materials used in the PCB are different
Taking ordinary double-panel as an example, the sheets generally have FR-4, CEM-3, etc., the thickness ranges from 0.6mm to 3.0mm, and the thickness of copper varies from 1oz to 3oz. The price varies greatly from specification to specification; In terms of ink, there is also a price difference between ordinary thermosetting ink and photosensitive green ink, so the difference in materials causes price diversity.
Second, the PCB uses different production processes
Different production processes can result in different costs. Such as gold-plated plate and tin-plated plate, the use of silk screen lines and dry film lines will form different costs, resulting in price diversity.
Third, the PCB itself is different in difficulty
Even if the materials and processes are the same, the difficulty of the PCB itself will result in different costs. If the two circuit boards are the same, but the line width and line spacing are different, one is greater than 0.2mm, and one is less than 0.2mm, which will result in different production costs. Because the difficult board has higher scrap rate, the cost will increase. .
Fourth, different customer requirements
The level of customer requirements will directly affect the yield of the board factory, such as a board according to IPC-A-600E, class1 requirements 98% pass rate, but according to class3 requirements may only have a 90% pass rate, resulting in different costs of the PCB factory.
Five, PCB manufacturers are different
Even the same product, but because of different PCB manufacturers' process equipment and technical level, different costs will be formed.
Six, different payment methods
At present, PCB manufacturers
generally adjust PCB prices according to different payment methods, ranging from 5% to 10%.
Seven, different regions
At present, in terms of geographical location in China, from south to north, prices are increasing, and prices in different regions are different.
