  • Use when probes or pogo pins require robust contact or current capability.

• If TP.V56.PB801 is a connector/contact in mechanical drawing:

  • Solid feature = a plated-through hole (PTH) or solid pin; ensure mechanical drill and annular ring per spec.
  • In footprint, mark as PTH with correct drill, plating, and solder mask opening.

• If TP.V56.PB801 refers to a 3D model/STEP (solid) for the part:

  • Provide/attach a solid 3D model (STEP/IGES) in the PCB library; align origin and reference points to footprint for ECAD–MCAD integration.
  • Ensure accurate keep-out, height, and collision geometry.

• Practical checklist to implement in your PCB tool:

  1. Confirm component type (test point, pin, connector, etc.).
  2. Choose pad type: SMD pad (solid copper) or PTH (plated hole).
