PCB proofing layout setting skills




PCB proofing, as a component of high-precision electronic products, has been a very common existence in life. However, we all know that domestic professional PCB proofing design needs different point settings in different stages, and large grid points will be 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. However, when there are too many and dense PCB proofing parts with good quality, the parts with limited height and low calorific value such as patch resistance, capacitance and patch IC will be placed on the lower layer. On the premise of fully ensuring the electrical efficiency 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 short, the overlapping of PCB proofing parts is not allowed under normal circumstances. The arrangement of PCB proofing parts should be compact, and its distribution should be uniform and consistent in the whole layout. Because PCB proofing is a very small part, the Zui small spacing between adjacent pad patterns of different components on the circuit board should be very weak, and the mechanical strength that the circuit board can bear should be considered in the actual setting.
In the layout design of PCB proofing, the units of the circuit board shall be analyzed and the layout design shall be carried out according to the function. When all components of the circuit are laid out, the following principles shall be met: arrange the position of each functional circuit unit according to the circuit process, make the layout convenient for signal circulation and keep the signal in the same direction as far as possible. Take the core components of each functional unit as the center and layout around it. The original parts shall be evenly, integrally and compactly arranged on the PCB proofing to minimize and shorten the lead and connection between components.
The above is the setting skills of PCB proofing layout. When we have a basic understanding of PCB proofing layout setting skills, we can better use it, and when it has problems, we can know how to check the problem, and even solve minor problems ourselves, without having to send them to the repair shop for repair.
