The wavy appearance of a circuit drawn on a napkin may have a certain organic charm to it, but it can be very difficult to read at times.Дue to creating the first PCB designs by hand, the use of a grid for the layout was very critical. Using gridded paper for sketching out schematics is only natural in order to keep your symbols roughly the same size as well as aligned. I remember as a child watching my dad sketch out electronic symbols, diagrams of the backyard shed, or even the layout of a model train set on that wonderful paper with the lines on it. There are of course many other benefits as well, and weвЂ™ll take a look at how managing grids in a PCB design can leverage those benefits in order to help you with your design.ДЇinding the origin of a grid is usually a matter of opening up a menu in your PCB design tools, but instead of jumping into the tools right away, letвЂ™s first look at grids historically. With a CAD tool design grid you can more easily work with parts and nets, find your way around the design, and add new circuitry as needed. IsnвЂ™t it interesting that the benefits that a gridded city plan gives its inhabitants are very similar to the benefits of using a grid in your PCB design CAD tools. Gridded cities are known for being more easily walkable, navigable, and adaptable when new city blocks are added. The principle of designing cities using blocks or lots separated by straight streets and intersected at right angles is still in use today. The practice of building cities on a grid plan has been around for a long time dating back to ancient places such as Babylon in the 17th century BC. The grid used in PCB design CAD tools has some similarities to a city grid plan
