PCB processing

The key step in the design of the hardware circuit is the drawing and processing of the printed circuit board. The drawing in these two links is a self-controllable part. Drawing according to functional requirements generally does not have principle errors, but the processing link will be more difficult. Control, therefore, it is necessary to write the processing instructions attached to the documents, and the more detailed it is, the more accurate the processing is. In addition to indicating the type of the plate, the dielectric constant, the thickness of the substrate, and the thickness of the copper, the plating form must also be indicated. , Whether to add solder mask, etc. Although it is more complicated, these contents can be solved very well through communication with the processing manufacturer. for reference only!
