Do you know how to avoid the risks in the PCB design process?

In the PCB design process, there are generally some hidden dangers. If possible risks can be predicted in advance and avoided in advance, the success rate of PCB design will be greatly improved. When evaluating projects, many companies will have an indicator of the success rate of PCB design per board. The key to improving the success rate of a board lies in the signal integrity design.

Do you know how to avoid the risks in the PCB layout and design process?

   There are many product solutions for the current electronic system design, and the chip manufacturers have already prepared them, including what chips to use, how to build peripheral circuits, and so on. In many cases, hardware engineers hardly need to consider the circuit principle, and only need to make the PCB by themselves.

   But it is in the PCB design process that many companies have encountered problems, either the PCB design is unstable or it does not work. For large enterprises, many chip manufacturers will provide technical support and guide PCB design. However, it is difficult for some SMEs to get support in this regard. Therefore, you must find a way to complete it yourself, so many problems arise, and it may take several editions and a long time to debug. In fact, if you understand the design method of the system, these can be completely avoided. Next, we will talk about three techniques to reduce the risk of PCB design.

 First, in the PCB design process, use simulation software to evaluate specific traces and observe whether the signal quality can meet the requirements. The simulation process itself is very simple. The key is to understand the principle of signal integrity and use it for guidance.

2. The signal integrity problem should be considered in the system planning stage. The whole system is built in this way. Can the signal be received correctly from one PCB board to another? This needs to be evaluated in the early stage, and it is not difficult to evaluate this problem. , Understand a little signal integrity knowledge, and can do it with a little simple software operation.

   Third, in the process of making PCB, risk control must be carried out. There are many problems that the simulation software has not yet solved, and the designer must control it. The key to this step is to understand where there are risks and how to avoid them. What is needed is knowledge of signal integrity.

Do you know how to avoid the risks in the PCB design process?

   If these points can be accurately grasped in the PCB design process, then the PCB design risk will be greatly reduced, the probability of errors will be much smaller after the board is returned, and the debugging will be relatively easy.

The above content describes how to avoid the risks that exist in the PCB design process, and I hope readers can help.
