PCB proofing layout setting skills
PCB proofing, as a high-precision electronic product component, is already a very common existence in life. But everyone knows that domestic professional PCB proofing designneeds to be set at different points in different stages, and large grid points are used for device layout in the layout stage. Let's take a look at the detailed PCB proofing layout setting skills.

In general, all small parts of PCB proofing should be arranged on the same circuit board, but in the case of too many and too dense parts for PCB proofing of good quality, chip resistors, capacitors, chip ICs, etc. Parts with limited height and low heat generation are placed on the lower level. And under the premise of fully ensuring the electrical performance of PCB proofing, these parts should be placed on a fixed grid so that they are arranged parallel or perpendicular to each other to achieve a neat and beautiful effect. In general, PCB proofing parts are not allowed. There is overlap. The layout of PCB proofing parts should be compact, and the distribution should be uniform and dense on the entire layout. Since PCB proofing is a very small part, the minimum spacing between the adjacent pad patterns of different components on the circuit board should be very weak, and the mechanical strength of the circuit board should be considered in the actual setting.

In the layout design of PCB proofing, the units of the circuit board should be analyzed, and the layout design should be carried out according to the starting function. When laying out all the components of the circuit, the following principles should be met: Arrange the position of each functional circuit unit according to the circuit flow to make the layout Facilitate signal circulation and keep the signal in the same direction as possible. With the core components of each functional unit as the center, the layout is carried out around him. The original parts should be uniformly, integrally and compactly arranged on the PCB proofing, and the leads and connections between the components should be minimized and shortened.
The above is the setting skills of PCB proofing layout. When we have a basic understanding of the PCB proofing layout setting skills, we can use it better, and when it has problems, we can know how to check its problems, and even solve minor problems by ourselves. Small problems, no longer need to be professionally sent to the repair shop for repair.
