Un prucessu impurtante di PCB history board is to convert the circuit of the physical circuit board into the PCB circuit file which can be processed by computer. One of the steps of this process is to scan the physical circuit board and process the scanned picture. This paper will introduce how to process the scanned picture file of PCB protection board to copy the circuit diagram in detail. I passi principali sò i seguenti:

1. Open the software PS and open the scanned files that need to be processed in the software (opening method: double-click the blank space of the PS software or click the menu file in the upper left corner to open or drag the file directly to the PS software);

2. Doppiu cliccà u stratu è cambià u nome di u stratu in “TOP”.

3. Place the mouse pointer on the horizontal and vertical rulers and hold down the left mouse button to pull out the horizontal and vertical guides respectively. (Se u regnu ùn hè micca visualizatu, presse Ctrl + R per apre u regnu);

4. Press Ctr + 1 per affissà a maghjina in grandezza vera (o appughjà Alt + pulley per ingrandà a maghjina u più pussibule), poi appughjà Ctrl + T per fà chì a maghjina entre in u statu di trasfurmazione libera, cum’è mostrata in a stampa sottu. Fate passà a puleggia di u topu per aghjustà l’Angulu di u ritrattu in modu chì u bordu di u bordu sia parallelu à a linea di riferimentu. Dopu l’ajustamentu, premete Enter per chì l’ajustamentu entri in vigore. Zoom in and check. Repeat if the board is not aligned. Note: In this process, if you want to move the reference line, you must press Ese to exit the free transformation state first. Per spustà a guida, premete a chjave V per cambià u mouse in u statu di strumentu di muvimentu è poi puntate a guida cù u mouse è trascinatela.

5. The scan chart at the top of the picture below has been adjusted. (At this time put a few more reference lines to confirm)

6. Dopu, trascinate a maghjina di scansione in fondu è premete Enter per cunfirmà, poi fate doppiu cliccà per rinuminallu.

7. Close the top scanning image and mirror the bottom scanning image as shown below, and press Enter to confirm:

8. Press Ctrl + T per entre in a forma di trasfurmazione libera cum’è quandu aghjustate l’imagine di scansione superiore. Pulsà a chjave di freccia nantu à a tastiera per spustà u stratu à pocu pressu à a linea di riferenza è poi aghjustà l’Angulu in modu chì u bordu di u bordu sia parallelu à a linea di riferenza. A figura seguente mostra l’effettu dopu l’aghjurnamentu di l’immagine di scansione sottostante:

9. Pone a cima di u stratu à u statu trasluzente per vede se i fori in cima è in fondu sò allineati, è i fori in i livelli superiore è inferiore sò allineati.

11. Then export the scan diagram after the underlying adjustment. (Altre operazioni sò listesse chì quandu si esporta a scansione di primu livello.)
