Printed Circuit Boards (PCB’s) are used in the full manufacture of circuits after the prototype stage.
You can use your breadboard circuits as a basis for designing a PCB but the best way to make an effective PCB is by using a Computer Aided Design package that will allow you to produce PCB’s. Some software will allow you to draw a circuit diagram and then will design the PCB for you – It is always worth checking manually however as some of these PCB’s are not 100% accurate.
You will need to think about how you will manufacture your PCB – will you send it away to be manufactured or do you have equipment to do it yourself?
