1. The relationship between the line width and the size of the via on the PCB board and the current passing through
The thickness of the copper foil of the general PCB is 1 ounce, about 1.4 mil, and the maximum current allowed by the roughly 1 mil line width is 1A. Vias are more complicated, not only related to the size of the via pads, but also to the thickness of the copper sinking on the hole wall after electroplating during processing.
2. To convert the PCB file to GERBER file and drilling data, and then hand it over to the PCB factory
Because electronic engineers and PCB engineers have different understandings of PCB, the GERBER file converted by the PCB factory may not be what you want. For example, if you define the parameters of components in the PCB file during design, you do not want these parameters to be displayed. On the finished PCB, but no explanation is given, the PCB factory will leave these parameters on the finished PCB. Therefore, it is more accurate to convert PCB files to GERBER files to manufacture PCBs.
Completing the design of a printed board diagram generally goes through the process of schematic input - netlist generation - definition KeepoutLayer - netlist (component) loading - component layout - automatic (manual) wiring and so on. The MovetoGird function can be used, which can automatically move components to grid intersections, which is of great benefit to improving the routing rate.
