What is the working principle of the circuit board?
On the most basic PCB, the parts are concentrated on one side and the wires are on the other side. Because the wire only appears on one side, the PCB is called a single panel. Multi-layer board, multi-layer wire, must be between the two layers of the appropriate circuit between the job, the bridge between the circuit called the hole (via).
The use of board-based insulation material to isolate the surface of the copper foil conductive layer, making the current along the pre-designed route in a variety of components such as work flow, amplification, attenuation, modulation, demodulation, coding and other functions.
the circuit board to make the circuit mini, visualization, for the fixed circuit production and optimization of electrical appliances play an important role in the layout. The circuit board can be called printed circuit board or printed circuit board, the English name is (Printed Circuit Board) PCB.
Circuit board works: the electronic components on the fixed and connected into the circuit. Circuit board name: circuit boards, PCB board, aluminum plate, high frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit boards, ultra-thin circuit boards, printing (copper etching technology) circuit boards.
