3 Tips to Reduce the Risk of PCB Design

In the PCB design process, if risks can be predicted or avoided in advance, the success rate of PCB design will be greatly improved. Many companies use a PCB design success rate indicator when evaluating projects.

 

The key to improving the design success rate is the design of signal integrity. In many current electronic system design product solutions, chip manufacturers have already made plans. Hardware engineers hardly need to consider the circuit principle, only need to make the PCB by themselves.

 

But it is in the PCB design process that many companies have encountered difficulties. The designed PCB is either unstable or does not work. For large enterprises, many chip manufacturers will provide technical support to guide PCB design, but it is difficult for some small and medium-sized enterprises to get this support. Therefore, small and medium-sized enterprises must find a way to complete it by themselves, which may require several boards and a long time to debug. In fact, if you understand more systematic design methods, these problems can be completely avoided.

 

Then, JRPanel would like to share with you 3 tips to reduce the risk of PCB design:

 

1. In the system planning stage, it is best to consider signal integrity issues. For example: If the entire system is built in this way, can the signal from one PCB to another be received correctly? Similar issues need to be evaluated in the early stage. It is not difficult to evaluate this problem. A little knowledge of signal integrity is enough. A little simple software operation is enough.

 

2. In the PCB design process, use simulation software to evaluate the specific wiring 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.

 

3. During the PCB design process, 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.

 

If these three points can be grasped well in the PCB design process, then the PCB design risk will be greatly reduced, the probability of error will be much smaller, and the debugging will be relatively easy.
