By definition, printed circuit routing refers to the process of organizing the flow of electrical signals to allow electrical components to connect. Its quality is based on several criteria that you will discover through this article.
Our tips for designing qualitative PCB routing
The design of printed circuit routing requires compliance with a few rules. Indeed, conception procedures are not as easy as some people may believe. To begin, know that you must determine your needs in advance, because the card must adapt to them. You can then choose between manual and automatic routing. In principle, PCB routing software must have an autorouting function. Thanks to it, tracing simple and direct connections does not take too much time. The automatic routing function also ensures the effectiveness of the solution that the tool offers. To find out more, you can contact the company to which you will entrust the design of your printed circuit routing. Additionally, it may also happen that you need to configure the automatic routing function.
Another important detail in setting up PCB routing is also the width of the tracks. They are responsible for transmitting electrical signals. It is then necessary to ensure that their width is compatible with the current which will pass through them. You must also be careful that the circuits of the analog tracks and the digital tracks are well separated. It is a guarantor of the security of verification signals. It is then necessary to ensure that the analog lines are the only ones to cross the analog voltage.
Other Important Details in PCB Layout Design
To measure voltages, a printed circuit must have at least one continuous ground plane. With power plans, it is to be placed in the internal layers of the card. The ground plane and the power supply plane will thus prevent the deformation of the electronic card . When it comes to space between tracks and contact points, the rules mandate a distance of 0.007 to 0.0010 inches. This space must also be respected for fixing holes to prevent possible electrocution. You must alternate their direction to limit crosstalk phenomena.
The procedures to follow to design the routing of a printed circuit
To do PCB routing, the company responsible for its design will study your project in advance. She will then diagram the device before installing the components. It will be after this step that it carries out the routing which will give the image of the printed circuit. The professional will then create a virtual prototype which will allow you to see the characteristics of the printed circuit in more detail. This prototype also makes it possible to identify and prevent errors that could occur during card assembly.
As you can see, designing a PCB layout is a lot of work. Also, it is strongly recommended to choose the company that will design it carefully.
