US Patent 7271348 Providing decoupling capacitors in a circuit board

A circuit board includes first and second reference plane layers. A first decoupling capacitor is mounted to a surface of the first reference plane layer, and a second decoupling capacitor is mounted to a surface of the second reference plane layer. Vias extend generally along a first direction through the circuit board. The first and second decoupling capacitors are aligned generally along the first direction to increase an amount of space through which the vias are extendable.
