Automotive communication module circuit board is the support of circuit components and devices in automotive products. It provides electrical connections between circuit components and devices. It is a basic component of various electronic equipment in automobiles. Its performance is directly related to electronic equipment. The quality is good or bad.
With the development of the information society, various electronic products often work together, and the interference between them is getting more and more serious. Therefore, the electromagnetic compatibility problem has become the key to whether an electronic system can work normally.
Similarly, with the development of electronic technology, the density of the automotive pcb communication module PCB is getting higher and higher, and the design of the automotive communication module has a great impact on the circuit interference and anti-interference ability. In order to obtain the performance of electronic circuits, in addition to the selection of components and circuit design, good wiring of automotive communication modules is also a very important factor in electromagnetic compatibility.
Although the car communication module PCB is an inherent component of the system, enhancing electromagnetic compatibility in the car communication module PCB wiring will not bring additional costs to the completion of the product. However, in the design of printed circuit boards, product designers often only focus on increasing the density, reducing the occupied space, making simple production, or pursuing aesthetics and uniform layout, ignoring the influence of circuit layout on electromagnetic compatibility and relying on a large amount of signal radiation To the space to form harassment.
A poor car communication module PCB wiring can cause more electromagnetic compatibility problems, rather than eliminate them. In many cases, even adding filters and components cannot solve these problems. Had to rewire the entire board. Therefore, to develop good pcb fabrication wiring habits at the beginning is a way to save money.
