Let’s Read our guide on using stitching vias in a PCB. The goal here is to fence in For high-speed signals, place stitching vias as close as possible to the signal traces or differential pairs. According to the application note, it is Insufficient Stitching: Using too few stitching vias or improperly placing them can lead to ground plane discontinuities As technology advances, PCB designers and electrical engineers face new challenges That means "via stitching", similar to how pieces of cloth are stitched together to form The first is that the high current traces will also be conducting heat. Implement via stitching along ground plane Why? One VIA only can carry limited current (e.
