Abstract
A multi-layer PCB has conductive vias () passing through multiple layers. A layer may have a conductive non-functional feature () physically contacting a via but not surrounding the via, to make the PCB more resistant to thermal stresses while, at the same time, reducing the parasitic capacitance compared to a prior art non-functional pad ().
