What is an impedance circuit board? Impedance circuit board refers to the circuit board that requires impedance control. A good laminate structure can control the characteristic impedance of the printed circuit board. Its traces can form an easily controllable and predictable transmission line structure called impedance circuit. plate. Impedance control means that under a high-frequency signal, the "resistance" generated by a certain line layer to its reference layer during transmission must be controlled within the rated range to ensure that the signal is not distorted during transmission. Impedance control is actually to make every part of the system have the same impedance value, that is, impedance matching. In a circuit with resistance, inductance and sum, the hindrance to the current in the circuit is called impedance. It is often expressed as Z, which is a complex number, the real part is called resistance, the imaginary part is called reactance, and the unit of impedance is ohm.

What is the function of the impedance circuit board? What is the significance of impedance to the circuit board, why should the circuit board have impedance? As a product that can effectively block alternating current, impedance circuit boards have been constantly being inquired in the market, from parameters to manufacturers, people who don’ t know how to inquire about the specific application scenarios of the product, and people who know how to do it Direct research on cost performance. So, what specific problems can impedance circuit boards help customers solve? What is the function of the impedance circuit board?

1. Solve the problem that the circuit board is not durable

The circuit board is a configuration that has been used for a long time. Since it is installed, it has been working day and night every time it is powered on. The long-term use makes the circuit board must be in a safe and stable state in order to ensure no errors. , and the impedance circuit board is a configuration that can control the circuit board current and ensure safe operation.

2. Address people’s psychological concerns

The essential meaning of the invention of the impedance circuit board device is to enable the circuit board in operation to be controlled in a certain state through physical principles to ensure the safety of operation, by controllability, and then to be able to control The relevant parameters of the circuit boards of different products are adjusted to manufacture product parts that are sufficiently suitable for the operation of the product

3. Solve the different construction requirements of different circuit boards

The products produced in different fields have different structures. This difference causes the reguired parts to have their own characteristics. Therefore, manufacturers are always looking for circuit boards that match their own products, as a circuit board that can resist the alternating current in the circuit board. The resistance device, the impedance circuit board also has different models and different parameters that change with the change of the circuit board.
