The Circuit Board:

The circuit board consist of thick and green colour plasic coded, it is not easily burnt. This circuit board has many pathways to send a voltage to one part to other parts in the circuit board. This circuit board only plays a vital role to cellphone to work bcoz the voltage from one parts of the spares will send to the others parts of the spares it all occurs only due to the help of circuit board path ways. This path will varies from board to board and companies to companies also. This circuit board is a rough and light weighted one and it cannot be burnt easily it is a washable board with the help of petrol or white petrol to keep the circuit board clean and neat for the voltage to circuit easily without any disturbances in the circuit board.

If cell phone gets problem it will be having a steps to identify the problem of the cell phone. If the problem was not found then directly clean the circuit board gentrly with petrol and keep it for dryness and then fix it in the cell phone. The 60% of the problem will be solved with this kind of method. The remaining 40% of the problem will be solved only by checking each and every parts of the circuit board only.This are all the main features of circuit board vital role in the cell phone.
