It goes without saying that many beginner designers make the mistake of cramming their components too close together on their first layout only to run out of space when it’s time to start routing. This happens most commonly with integrated circuits which have lots of pins that need to be connected all over your board. If you don’t give this one component enough room to breathe, then you’ll likely run out of space and will have to start your layout over again from scratch. When placing components, always be thinking about how you’ll route them, and leave enough room between parts to make that process easy.
