5 Basic Steps to a Successful PCB Layout - Part 2

This is the second of five parts from guest blogger, Stilwell Baker, covering successful PCB layout. Last week they covered parts libraries.

Mechanical constraints matter: Trace density, layer count, and physical size all matter, but the parts still need to fit on the board.

  • Connector locations and orientations can quickly limit placement and routing flexibility
  • Finish the mechanical specification before moving into the placement and route of a design. Changes to mechanical specifications during placement and routing can significantly increase the amount of time in layout.
  • Be sure to budget extra space for mechanical interfaces that plug into the board.
  • You’ve checked your part spacing and and connector locations in the x and y direction, now it is time to make sure that you have accounted for component heights in the z direction. Check for external mechanical interferences. For instance the curvature of the case that the board is mounting in, the motorized arm that moves along the adjacent interface, ….. Sometimes an IDF or DXF transfer to check your design in the larger mechanical world is the best thing.

Next week: Be careful with layer count.
