Fast rising edges can create crosstalk, and you should always verify the required trace spacing with simulations or measurements. The goal here is to limit crosstalk, but this rule of thumb was developed at a time when crosstalk was much lower. A common rule of thumb is to set the minimum spacing between single-ended traces as triple the width of the traces. Three common cases where you need to specify minimum trace spacing and width together in a design are: Different rules become quite important in different applications, and designers should take time to understand these various rules when preparing a new design. There are many rules that relate to routing and trace sizing in PCB design. What is the Minimum Trace Spacing and Width? Let’s look at what it takes to set up your routing rules and trace spacing in Altium Designer ®.

Fortunately, PCB design software has tools and resources that make the job of setting your routing rules up a lot easier than it used to be.

However, you need to configure routing rules for your specific application as minimum trace spacing and trace width requirements can be very different in various applications. The CAD tools in PCB design software have been set up to help you create your routing rules, and these capabilities have been around for a long time. The more rigid the design requirements, the more dangerous this can be, even to the point of forcing you to re-do major sections of your routing in order to meet your design requirements. This can be dangerous though as you may inadvertently route a trace routing at the wrong width, or pack your routing in so tightly that you don’t have the room to make any width corrections later on. Many designers would prefer to jump in and start trace routing without going through this setup process first.

Taking the time to set up routing rules to govern the minimum trace spacing and trace width for PCB layout can be tedious.
