Sound Systems Design Portfolio (pg19)

Spot the mistakes.

1. there's no wires or components connected to pad 3 of the IC. it can be fixed by adding components to it and connecting it to one of the rails.

2. the wire of pad 5 doesn't connect to anything, it can be fixed by connecting it to the positive or negative rail.

3. the negative rail is to thin so the current won't be able to flow well. it can be fixed by making the rail on diptrace thicker.

4. pad 4 doesn't have wire connecting the resistor to the negative rail.

5. there is no pad connected to the end of the negative rail. on diptrace you could just add a pad to the end of the rail.

6. the writing is too big. It can be fixed by making the writing smaller on dip trace.

7. the wire isn't connected all the way to the negative rail which is a problem. before you make your PCB you should just check if everything is connected right.

8.1 the wires are crossing over each other, it can be fixed by separating them and putting pads at the end of the wires.
8.2 the wires aren't in line so the current won't flow, it can be fixed by moving the wire to the side.

9. once again the track doesn't connect to anything, it can be fixed by joining it to the negative rail.
