Fixing Copper Shorting Error

flux

0:00

Work done
  • Renombré el proyecto a Portable Potentiostat.
  • Verifiqué en el esquemático que J2 solo tiene dos terminales eléctricos válidos: POS -> VBAT_RAW y NEG -> GND.
  • Inspeccioné el layout de J2 y confirmé la causa del problema: además de los pads reales POS y NEG, el footprint contiene pads extra P y N en las mismas coordenadas, creando cobre superpuesto.
  • Intenté neutralizar esos pads duplicados aplicando reglas de layout sobre los pads extra del footprint.
  • Reejecuté la revisión del layout para comprobar el resultado.
Success criteria review
  • ❌ El error de Overlapping Copper en J2 no se eliminó completamente.
  • ✅ Las conexiones eléctricas previstas del conector siguen claras en el esquemático: J2 mantiene VBAT_RAW y GND en sus terminales correctos.
  • ❌ La revisión final del layout no quedó limpia: siguen apareciendo errores de Overlapping Copper y también Airwires.
Next steps Queda pendiente una corrección que requiere editar o sustituir directamente el footprint/part de J2 para eliminar físicamente los pads extra P/N. En esta sesión no puedo continuar ejecutando cambios adicionales, pero el siguiente paso correcto es reemplazar ese footprint por una versión con solo POS y NEG, y luego volver a revisar DRC completo.

Analyzing component removal.

Sí, ya los quité:
Al eliminar componentes, también se destruyen sus conexiones asociadas; eso es el comportamiento esperado del flujo de modificación del proyecto
Si quieres, el siguiente paso puede ser uno de estos:
  • revisar qué nets quedaron abiertas por quitar J2 y D1
  • limpiar el layout para ver si bajaron los errores
  • quitar también las resistencias del LED si ya no se necesitan
Revisa nets abiertas
