1. Keep traces straight, Try to avoid 90-degree turns use two 45 degrees.
2. Double, even triple-check the layout, Having a fresh pair of eyes look it over,
3. Trace thickness & spacing.
The important characteristics to consider when selecting a trace
width include:
The current capacity of the trace (how much current will flow through it)
The allowable spacing between traces.
The size and pitch of the pads that the trace will be connecting to
4. Try to keep all connections on one side of the PCB.
5. Take into account the component package.
Most electronic components come in standardized packages. A package type has a well-defined set of physical dimensions that the component has to conform to. For each package, normally the pitch spacing, height, and general shape are defined.
Placement of Components
Place big components first- e.g. microcontroller
Place components in separate functional groups
Put a ground plane under all components
