Best answer

If copper on a circuit board is exposed, it can cause the following problems:

1. Poor contact: Exposed copper wires may affect the contact of the devices connected to them, causing partial or complete failure of the circuit.

2. Short circuit: Exposed copper wires can easily cause short circuits between circuits, causing damage to the circuit board and causing irreversible damage to other devices.
