There is no difference between the circuit board and the circuit board, which is essentially the same.

The circuit board is only a design, the production of a good substrate, circuit board refers to the various components have been installed on the circuit board. The name of the circuit board are: circuit board, PCB board, aluminum substrate, high frequency board, PCB, ultra-thin circuit board, ultra-thin board, printing (copper etching technology) circuit board and so on.

The circuit board makes the circuit mini and intuitive, which plays an important role in the mass production and optimization of the fixed circuit with electrical layout.

Circuit board: On the insulating substrate, according to the predetermined design of the formation from point to point to connect the wire, but there is no printed components of the printed board.

Circuit board: On the insulating substrate, according to the predetermined design of the formation of wire from point to point, and printed components of the printed board. There is a circuit board is the kind of electronic components. And the circuit board is that kind of PCB board. Without electronic components, the most contact is the circuit board, the motherboard is the circuit board.
