Do you know the factors that affect the cost of PCB pattern making?

Do you know the factors that affect the cost of PCB plate making? When completing a complete PCB project, you are often more concerned about layout and wiring. What is often most easily overlooked is the PCB manufacturing cost. Let’s understand what factors will affect the PCB. The cost of plate making?

1. Number of wiring layers:

The more layers the design has, the easier it is to wire, but the price rises linearly with the number of layers, and the final board production price may double.

2. Via:

If it is not limited by the device pitch or design density, try to use vias with a diameter above 0.25mm and vias with a diameter smaller than 0.25mm. Most PCB manufacturers need to charge a certain fee.

3. Plug the hole in the plate:

Unless there are restrictions on signals, layout, and packaging, try not to use them.

4. Back drilling:

Using it on a backplane or a single board with high-speed signals will increase the cost by about 10% to 20%.

5. Line width and line spacing:

Usually if it is less than 3.5mil, the manufacturer will charge more.

6. Plate:

Unconventional sheets such as high TG sheets, halogen-free sheets, and high-frequency sheets will increase the procurement cycle of PCB manufacturers, which means increased production costs. Some high-frequency plates can be mixed with ordinary plates, which can reduce part of the production cost.

7. HDI and blind and buried via design:

This item increases the cost proportionally, so it is best not to use it if the package allows it. Tip: BGA packages with a pitch of 0.65mm and above can all achieve through-hole fan-out. Some 0.5mm BGA packages can achieve through-hole fan-out based on the pad size and available pin distribution.

8. Surface technology:

Immersed gold, immersed tin, immersed silver, and gold fingers will increase the cost. Of course, these items need to be specifically considered according to the type of product designed. The above are the factors that affect the cost of PCB pattern making. I hope it can help you.
