PCB board cutting is an important content in PCB design. But because it involves sandpaper grinding board (belong to harmful work), tracing line (belong to simple and repetitive work), many designers do not want to engage in this work. Even many designers think that PCB cutting is not a technical job, junior designers with a little training can be competent for this job. This concept has some universality, but as with many jobs, there are some skills in PCB cutting. If designers master these skills, they can save a lot of time and reduce the amount of labor. Let’s talk about this knowledge in detail.

First, the concept of PCB board cutting

PCB board cutting refers to the process of getting schematic and board drawing (PCB drawing) from the original PCB board. The purpose is to carry out later development. Later development includes installation of components, deep testing, circuit modification, etc.

Two, PCB board cutting process

1. Remove the devices on the original board.

2. Scan the original board to obtain graphic files.

3. Grind off the surface layer to obtain the middle layer.

4. Scan the middle layer to get the graphics file.

5. Repeat steps 2-4 until all layers are processed.

6. Use special software to convert graphics files into electrical relation files -PCB drawings. With the right software, the designer can simply trace the graph.

7. Check and complete the design.
