If you want to learn Reverse Engineering you can use photoshop as aid tools. For example, This 12-keys keypad failed after years of daily use. No schematic or replacement parts from the original manufacturer. The only option was to replace it with an off-the-shelf telephone-style keyboard.Following the maze of each and every PCB track in a circuit is boring and error-prone, so here is the easier way to get the job done.
- Take a picture of the PCB, and feed it through a photo-editing program.
- Select the bucket fill tool and choose the color you like to paint the track.
Tip: vivid colors work best
- Click on on the track you want to highlight.
2nd Trick is “Transparentize” the PCB to see connections on both sides. Take the picture for both side of the PCB then to overlap the pictures in photoshop, and get them exactly the same size and alignment.
