How can I trunk route a pair of tracks between BGA pads?

Here we present a simple method to route a pair of tracks with a defined gap. This is ideal for placing tracks from a BGA or similar footprint. As the method uses a defined gap and track width, it is also suitable for transmission lines. The DSPCB Engineer feature used to achieve this is the 'Trunk Routing' tool which makes the process very simple.

In this video, we illustrate how to set the required settings.
