What are the functions of the components of the circuit board?
At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge but also an opportunity for PCB factories. If PCB factories are determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and PCB factories can get opportunities for further development.
The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of him. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields.
    There are essential differences between the components and devices of the circuit board. The components of the circuit board are resistance, capacitance, and inductance. They do not change the internal molecular structure during production, that is, the performance only depends on the material. Devices generally refer to various semiconductors, such as diodes, triodes, etc., whose molecular structure needs to be changed during production. For example, when the triode is produced, the majority carrier concentration in the emitting area is greater than that in the base area, which changes the molecular structure in it, so it is a kind of device. Let's talk about the functions of several components according to the meaning of the question.

    The function of the circuit board resistance: The resistance is widely used in the circuit, and it has several functions, such as shunting, voltage dividing, current limiting and so on. Resistors are shunted in parallel and divided in series. As for current limiting, the light-emitting diodes we use generally have a resistor in series. The function of this resistor is to limit current, so as not to burn the light-emitting diodes when the current is too large.
    The role of the circuit board capacitor: the role of the capacitor is more, there are filtering, bypass, coupling, energy storage and so on. What we often see and use on the circuit board is the filter function, as long as the power circuit will use the capacitor filter. No matter what the function is, it uses the characteristics of the capacitor to block the direct current and pass the high resistance and low resistance.
    The function of circuit board inductance: Inductance is not used in the circuit as much as resistance and capacitance. Its main functions are filtering, oscillation, delay, trapping, etc. No matter what it is, it uses the inductance to pass through and isolate the current, and the pass through is low and high. The characteristics are opposite to capacitance. The figure below is an LC filter circuit composed of inductors and capacitors. We are not an agent
