Depopulate

verbStandard termPCBs

To intentionally leave specific component footprints empty during assembly.

To omit components from a circuit board during the assembly process. This is usually done to save costs on features not needed for a specific product tier, or to remove parts that were only required for prototyping and debugging. The bare copper pads remain on the finished board.

We need to depopulate the debug headers and the extra flash memory for the production run.
