Schematics

  • Net-names, use shared labels when components on schematics are not close together or when drawing a wire would be too messy.
  • Avoid wire cross overs. The fewer the better.
  • Don't run wires over components. Few to no exceptions for this one.
  • Higher voltage at top, lower voltage at bottom.
  • Inputs on left, Outputs on right.
  • Align labels with parts
  • Rotate components

PCB Layout

  • GND is critical and must be either wide traces or a good plane.
  • Power is next most critical and should have a bypass cap next to each load and should also use heavy traces or planes.
  • Primarily horizontal traces on one layer, primarily vertical traces on other layer.
  • Short traces are better - Frequency of signals?
