Floating Copper Error Resolution

flux

0:30

Capito. Allora la cosa utile adesso è gestire il rischio, non rimuginare.
Cosa significa davvero
  • Se il preview JLC mostrava U1 ruotato, c’è un rischio reale di orientamento errato in assembly.
  • Però il preview JLC può anche avere problemi di allineamento/mapping e non essere perfettamente affidabile da solo; per file e screenshot bisogna sempre collegare l’immagine al contesto reale del progetto, non trattarla come verità assoluta
  • Nei file allegati e nei preview la regola giusta è: essere specifici sul rischio e passare a un recovery path chiaro, non generico
Cosa fare subito
Se l’ordine è già partito, fai queste 3 cose:
  1. Contatta subito JLCPCB
  • Apri il ticket/order note e scrivi che vuoi una manual placement/orientation check per U1, U6, Q2, Q1, D2, D3.
  • Dì esplicitamente che il CPL preview sembra avere orientamenti errati.
  1. Allega uno screenshot corretto del PCB
  • Quello con il layout reale di Flux.
  • Evidenzia soprattutto U1 con una nota tipo:
    • “tab a destra/sinistra” a seconda della tua vista di riferimento
    • “do not rotate 180 degrees from PCB layout reference”
  1. Chiedi conferma prima del montaggio
  • Chiedi che ti mandino conferma DFM/CAM o screenshot placement prima di assemblare, se l’ordine è ancora in quella fase.
Messaggio pronto da mandare a JLC
Puoi incollare questo:
Please pause assembly if possible and manually verify component orientation against the PCB layout for these parts: U1, U6, Q1, Q2, D2, D3.
The CPL preview appears to show at least U1 rotated incorrectly relative to the PCB footprint.
Please use the PCB silkscreen / pad orientation as reference and confirm placement before assembly.
Quanto è grave
  • Se l’ordine è ancora in review / pending / CAM, potresti ancora salvarlo.
  • Se è già in assembly completed, allora bisognerà aspettare la scheda e verificare.
  • I componenti più critici se girati male sono:
Quando arrivano le schede
Prima ancora di alimentarla:
  • ispeziona visivamente U1
  • verifica polarità di D2, D3, D1
  • verifica orientamento di U6
  • misura resistenza tra VIN e GND
  • poi alimenta con corrente limitata
Mia raccomandazione
Scrivi subito a JLC adesso.
È la mossa con il miglior rapporto impatto/tempo.
Se vuoi, nel prossimo messaggio ti preparo un testo ancora più preciso, già formattato per ticket JLC, in inglese corto.
