Direct plane attachment for capacitors

A method for directly attaching a capacitor to a conductive plane of a printed circuit board, the method comprising:

• providing a printed circuit board, the printed circuit board having a first signal layer, wherein the first signal layer is the outermost layer of the printed circuit board, and wherein the printed circuit board also includes a first conductive plane and a second conductive plane, the first conductive plane arranged between the second conductive plane and the first signal layer;
• forming a cavity in the printed circuit board, wherein the cavity extends from the first signal layer to the first conductive plane;
• placing a capacitor in the cavity;
• directly attaching a first terminal of the capacitor to the first conductive plane;
• placing a second terminal of the capacitor within the periphery of an opening of the first conductive plane;
• and
• electrically coupling the second terminal of the capacitor to the second plane by a via.
