Creating high quality electronics schematics
SMRTR summary
A clean circuit diagram can be the difference between success and frustration. Veteran electronics designer Phil Schamp has shared fourteen practical guidelines for creating readable schematics that will save countless headaches down the road.
"Stick to the grid," Schamp advises, a foundational principle that begins his recommendations. His guidance emphasizes visual clarity through consistent routing—keeping power flowing upward, ground downward, and signals moving horizontally across the page.
The most striking visual examples show the dramatic difference between "spaghetti" wiring and organized connections. One before-and-after comparison transforms an unreadable tangle into a logical circuit that tells its own story.
Particularly valuable is Schamp's advice on component symbols: "Component symbols are supposed to represent the function of the part. They don't need to be a rectangle with pins placed in the same order and location as the physical device pins."
His emphasis on documentation stands out in a field where future troubleshooting is inevitable. "Make notes," he insists, especially for calculated values and design decisions. "You'll thank yourself later."
