Abstract:
1. A circuit board comprising: a board substrate having opposite first and second sides, the board substrate having a thickness measured along a z-axis that is perpendicular to the first and second sides; plated thru-hole (PTH) vias extending along the z-axis from the first side into the board substrate, the PTH vias arranged to form multiple signal pairs; signal traces directly coupled to the PTH vias and extending perpendicular to the z-axis in the board substrate, wherein the signal traces and the PTH vias are configured to transmit differential signals; and ground columns extending along the z-axis in the board substrate, the ground columns being distributed relative to the signal pairs to form shield arrays, each of the shield arrays surrounding one of the signal pairs, wherein the ground columns comprise microvias.
