Copper is vital to the functionality of mobile phones, primarily acting as an electrical conductor. According to available information, copper is used as an electrical conductor in the mobile-phone circuit board.
Here's a breakdown of copper's role:
-
Electrical Conductor: Copper's high electrical conductivity makes it ideal for transmitting electrical signals throughout the phone's internal circuitry. This is crucial for all phone functions, from making calls to running applications.
-
Circuit Boards: The circuit board, or printed circuit board (PCB), is the backbone of the phone. Copper traces are etched onto the board to create pathways for electrical current.
-
Material Source: Copper is typically mined or extracted as copper sulphides from large, open-pit mines.
In summary, copper is essential for the operation of a phone due to its excellent conductivity and use in the circuit board.
