Electromagnetic compatibility (EMC) refers to the ability of electronic devices to function harmoniously in their electromagnetic environment without causing or being affected by electromagnetic interference (EMI). The goal of EMC design is to enable electronic devices to resist external interference while minimizing the electromagnetic interference they emit to surrounding devices
PCB design involves two critical stages: component layout and circuit connection wiring. The layout is the arrangement of circuit components within the PCB’s wiring area. A well-thought-out layout directly affects the ease of subsequent wiring and significantly impacts the PCB’s overall performance. In addition to meeting circuit functionality and performance requirements, a good layout considers manufacturability, inspection, and maintenance. Components should be placed evenly, neatly, and compactly, ensuring that leads and connections are short, minimizing interference and signal transmission delays.
RF and microwave signals are very sensitive to noise -much more sensitive than high -speed digital signals. This means that you need to minimize the noise, bell, and reflection, and at the same time be careful to deal with the entire system.
Returning the signal with the least inductance -the ground floor below the signal will be easier to ensure this path.
Discipline matching is important. With the rise of RF and microwave frequency, the tolerance will become smaller. Generally, the PCB drive needs to be fixed, such as 50 ohms, which means that during the transmission and sending to the receiver, the drive outputs 50 ohms.
The transmission line that is curved due to wiring restrictions should use a curved radius that is at least three times larger than the central conductor width. This will minimize characteristic impedance.
It is necessary to minimize the return loss, whether it is reflected by the signal or the bell. There will always be a return path, but your design should guide it and prevent the return from multi -layer leakage through the PCB.
PCB is also known as printed circuit board, which can realize the line connection and function realization between electronic components, and is also an important part of power circuit design. Today, we will introduce the high-frequency PCB circuit wiring skills in PCB design.
In today’s fast-developing electronic age, PCB printed circuit boards are the heart of electronic products, and their design and manufacturing technologies are constantly improving, especially in the field of high-frequency circuits. High-frequency circuit design is not only related to the performance stability of the product, but also directly affects signal integrity and electromagnetic compatibility (EMC).
