PCB Tech - PCB manufacturers: Four factors controlling PCB costs

So many PCB manufacturers in Guangdong, what standards do they use to control costs? This is what our majority of PCB circuit board users need to understand.

For PCB manufacturers in Guangdong, there are 4 major factors involved in controlling PCB costs. The editor summarizes the following 4 points:

1. In the case of the same area, the more PCB layers, the more expensive the price. The design engineer must use as few layers as possible to complete the PCB design while ensuring the quality of the design signal.

2. In the case of a certain number of layers, the smaller the size of the PCB, the lower the price will be. If the design engineer can reduce the size of the PCB without affecting the electrical performance in the PCB design, the size can be reduced reasonably and the cost can be reduced.

3. The main parameters affecting PCB manufacturing include minimum line width, minimum line spacing, minimum drilling, etc. If these parameters are set too small or the process capability has reached the minimum limit of the PCB factory, then the yield of PCB will be lower and production The cost of manufacturing will increase. Therefore, in the process of PCB design, try to avoid challenging the limits of the factory, set reasonable line width and line spacing, and drill holes. In the same way, through holes can complete the design, try not to use HDI's blind and buried holes, because the processing technology of blind and buried holes is much more difficult than that of through holes, which will increase the production cost of PCB.

4. There are many classifications of PCB boards, common paper-based printed circuit boards, epoxy glass fiber cloth printed circuit boards, composite substrate printed circuit boards, special substrate printed circuit boards, and metal substrates. There is a big gap in the processing of different materials, and some special materials will have a longer processing cycle, so in the design, try to choose materials that meet the design requirements and are more common and inexpensive, such as FR4 materials.

Editor's summary: If you are still struggling to choose a PCB manufacturer. The editor quietly tells you that the PCB quality produced by ipcb strictly according to the standard is excellent, and it is a good choice for you!
