DFM is not just another pre‑production checkpoint. For experienced hardware engineers, it’s a critical part of a robust design‑review workflow. With the DFM Analysis Plugin in PCB‑Investigator, manufacturing‑critical parameters can be validated directly inside the layout environment—rule‑driven, detailed and fully reproducible.
The checks go far beyond standard DRC validation:
- Selective Soldering: Verifies THT component clearances, including single‑pad, multi‑pad and multi‑pad‑row rule sets to detect opposite‑side interference.
- Fiducial Marker Verification: Ensures AOI‑compliant placement according to defined specifications for precise optical alignment.
- Panelization Control: Confirms that the panel geometry meets defined production constraints and dimensional tolerances.
- Testpoint Checks: Validates spacing and placement tolerances to secure reliable electrical access during ICT or flying probe.
- Solder Paste Analysis: Checks paste objects, mask clearances and copper definitions to prevent bridging and solder‑related defects.
- Trace Under Component: Identifies unauthorized copper routing beneath component bodies, avoiding thermal and electrical risk zones.
Results are visualized with clear severity levels (favorite/acceptable/fail) and can be exported for structured documentation, including integration into extended design reports. For teams handling high complexity or variant‑rich product lines, this means consistent rule application, fewer redesign cycles and measurable manufacturing robustness.
