Reinforcing Vias

What are Reinforcing Vias?

Otherwise known as “stitching vias”, reinforcing vias connect conductor areas on different PCB layers together in definable patterns.

Benefits of Stitching Areas Together with Reinforcing Vias

• You can stitch conductor areas that require a low impedance between layers much more quickly and predictably
• It makes it easier to avoid errors such as overlapping via clearance gaps that create plane discontinuities
• You can be more reassured you have followed application-note rules for items like shield stitching
• It makes it easier to edit your PCB design to, for instance, change the vias types used for stitching
