In the layout of the PCB board design, the unit of the board should be analyzed and the layout design according to the function. When all the components of the circuit are arranged, the following principles should be met: 1. According to the circuit flow, arrange the position of each functional circuit unit to facilitate signal circulation, and keep the signal as consistent as possible. 2. Center around the core components of each functional unit. The components should be evenly, integrally and compactly placed on the PCB board design to minimize and shorten the connection between the leads and components. 3. For circuits operating at high frequencies, the distribution parameters between the components should be considered. In general, the circuit should be arranged in parallel as much as possible, which is not only beautiful, but also easy to install and mass-produce. Special components and layout design Special components refer to key components of the hig...
In the PCB board design process, the success rate of printed circuit board design will be greatly improved if the possible risks can be predicted and avoided in advance. The key to improving the success rate of the first board is the signal integrity design. Currently, there are many product plans for designing electronic systems, and chip manufacturers have already completed these plans, including what chips to use and how to build peripheral circuits. Hardware engineers rarely need to consider circuit principles, they only need to make their own printed circuit boards. But in the printed circuit board design process, many companies have encountered difficulties, either the printed circuit board design is unstable or not working. For large enterprises, many chip manufacturers will provide technical support to guide printed circuit board design. However, it is difficult for some SMEs to get support in this regard. Therefore, we must find a way to accomplish it ourselves, which ...
