Soft PCB board design

During the process of soft PCB board design, if we can predict the possible risk in advance, to avoid ahead of time, soft PCB board design success rate will increase. Many companies to evaluate project when there will be a soft PCB board design index of success rate of a plate.

Improve the success rate of a board the key lies in the signal integrity design. Electronic system design at present, there are a lot of product solutions, chip makers have been done, including the use of any chips, periphery circuit how to set up, and so on. Hardware engineer many times almost don't need to consider the problem of circuit principle, only need soft PCB board to themselves.

But it is in the process of soft PCB board design, many enterprises have met the problem, either PPCB B designed soft board is not stable, either don't work. For large enterprises, chip manufacturers many will provide technical support, to guide the soft PCB board design. But some of the small and medium-sized enterprise is difficult to get support on this. Must, therefore, to find a way to own work, and produced many problems, may need to do several version, debugging for a long time. Actually if they understand system design methods, these can be avoid completely. Next, we'll talk about three techniques of reducing the risk of soft PCB board design.

1, the system planning stage had better consider the signal integrity problems, that of the whole system and the signal from a soft PCB to another piece of PCB board can be received correctly? In the previous assessment, assessment of the problem is not difficult, know a little knowledge of signal integrity, a little simple software operation can achieve it.

2, in the process of soft PCB board design, using the simulation software to evaluate the specific line, observe the signal quality can meet the requirements, the simulation process itself is very simple, the key is to understand the principle of signal integrity of knowledge, and used to guide.

3, do PCB in the process of soft board, be sure to control the risk. There are many problems, there is currently no way to solve the simulation software, designers must be controlled artificially. The key step is to understand where there will be a risk, how to do to avoid risk, needs or signal integrity of knowledge.
