Routing Techniques

Tips for a proper, organized PCB

Good Routing Techniques

  • Do not route traces close to the edge. This will create massive amounts of EMI. 
  • Do not place EMI-emitting components, such as crystals, near a board edge.
  • Surround pulsating traces with proper ground plane fill to reduce EMI.

Verticals and Horizontals

  • DoUse not route both verticalsfront and horizontalsback onfor thehorizontal sameand layervertical unlesstraces necessary.

  • Pick sides which do not force the abuse of vias for routing smd components.
  • Let busses take precedence over singular traces (explained below).

Trace Bus

  • Route many traces going in the same direction together for efficient use of space.
  • This can be used to efficiently break out many traces from the controller.

Aesthetics

  • Space things evenly.
  • Bundle traces together if not susceptible to interference.
