PCB price influencing factors

First, the materials selected for the pcb board are different in PCB price.
Sheets generally have FR-4, CEM-3, etc., the thickness of the sheet varies from 0.6mm to 3.0mm, and the thickness of copper varies from H/H Oz to 3 Oz. These sheets cause a huge cost gap.

Second, the different production processes used in PCBs result in PCB price diversities.
Different production processes can result in different costs. For example, gold-plated plates and tin-plated plates, the shape of the boring (milling) plate and the beer (punching) plate, the use of silk screen lines and dry film lines will form different costs, resulting in price diversity.

Third, the price diversity caused by the difficulty of the PCB itself.
Because of the high scrap rate of the difficult board, the cost will increase, which will result in the diversity of PCB prices.

Fourth, different customer requirements will also result in different PCB prices.
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.

Fifth, regional differences cause PCB price diversity.
Even if the same product, but because of different manufacturers' process equipment and technical level, different costs will be formed.
