Why do I need an impedance control PCB?
Recently, we have seen that the switching speed of SMT chip factory equipment is constantly improving. Often, these devices suddenly become complex and fast. For example, with the increase of equipment operation speed in smt processing factories, the signal integrity problem has become very repetitive. This means that today's equipment must be able to solve any SI problem.
Therefore, you cannot always regard PCB routing as point-to-point connection in smt chip production. Instead, start thinking of them as transmission lines. In addition, you must understand the importance and necessity of impedance matching in eliminating or reducing the impact on SI. Be aware that by using good design methods and practices, you can easily prevent possible SI problems. In this case, controlled impedance can help you mitigate or avoid SI problems.
Other reasons why you need an impedance control PCB include
Need more signal power
The PCB tracking function transmits the signal power of the driver device to the device that will receive it. Here, power must be transmitted over the entire length of the cable. However, the maximum signal power can only be achieved through the matching impedance of the PCB.
This is one of the reasons why impedance control PCB is required. This type has an impedance matching function that allows the device driver to provide sufficient power and end at the receiver.
Improve performance
If you are looking for a PCB that can ensure high-quality device performance, you should select an impedance control PCB.

One of the reasons for the failure of most equipment in terms of integrity and signal power in smt processing is poor PCB layout and design. The layout stage in PCB manufacturing process is usually a very critical stage. If one is not careful, high-speed signals are likely to degrade when they travel to the receiver.
Devices controlled by impedance control PCBs typically use less energy and perform faster. This PCB type allows the device to run better for a long time, thereby improving its control reliability and value.
Control energy flow
The impedance control PCB in the smt chip processing plant does use less energy. However, if you also need to control the energy flow in the project, the impedance control PCB is a good choice. The fact is that controlled impedance is important when transitioning from a lower ohmic environment with impedance to a higher ohmic environment.
Why is that? These changes may cause the energy to be reflected, which looks like a strong and intense pulse. These pulses disrupt the flow of energy. Therefore, it is necessary to use an impedance control PCB if your application processes digital devices that work at high power, such as RF applications.
Manage EMI
If you use an impedance control PCB, you do not have to worry about circuit interruption due to electromagnetic interference.
In the PCB world, the reflected energy pulse can completely destroy the circuit. This interruption usually extends to adjacent components. In addition, it is likely that the energy flow will be interrupted and the product operation will fail.
