Rigid PCB design and implementation of commercial manufacturing to follow these rules
Rule 1: Select the correct grid - set and always use the grid spacing that can match the most components. Although multiple grids seem to be useful, engineers can avoid problems at intervals and maximize boarding if they can think more about Rigid PCB layouts early. Since many devices are available in a variety of package sizes, engineers should use products that are best for their own design. In addition, polygons are essential for copper cladding on the circuit board. Multilayer circuit boards typically produce polygon fill errors when performing polygonal copper cladding, although they are not as standard as a single grid, but provide the required board life The
Rule two: keep the path the shortest and most direct. This sounds simple, but at every stage, even if it means changing the board layout to optimize the cabling length, keep it in mind. This is also particularly applicable to system performance is always partially limited by impedance and parasitic effects of analog and high-speed digital circuits.
Rule 3: Use the power tier to manage the distribution of the power cord and ground as much as possible. The copper layer of the power supply layer is a quicker and simpler option for most Rigid PCB design software. By sharing a large number of wires, it is guaranteed to provide the highest efficiency with minimal current or voltage drop, while providing adequate ground return paths. If possible, you can also run multiple power lines in the same area of the board to see if the ground plane covers most of the layers of a Rigid PCB, which facilitates the interaction between lines running on adjacent layers.
