Abstract:
A printed circuit board (PCB) includes a plurality of layers and electronic components connected to its top surface. The PCB also includes a plurality of trace layers, each located at a respective depth within the layers of the PCB. A plurality of vias provide signal pathways for the trace layer. Upon their manufacture, the vias include a stub portion not necessary for the signal pathways and causing degradation of the integrity of these signal pathways. Embodiments mill the bottom of the PCB to form a variable-depth cavity. The different milling depths of the variable-depth cavity are selected to remove the stub portions of the plurality of vias and the dielectric material between the stubs. By configuring the PCB power planes as the topmost trace layers, decoupling capacitors may be located at the greatest depth of the variable-depth cavity, thus reducing the loop inductance in the power circuit of the PCB.

Claim (Index 21):
A controller of an IHS (Information Handling System), the controller comprising:\n a printed circuit board (PCB) comprising a plurality of layers and a plurality of electronic components connected to the top surface of the PCB, the PCB further comprising:\n a plurality of trace layers, wherein each trace layer is located at a respective depth within the plurality of layers of the PCB; \n a plurality of vias, wherein each via provides a signal pathway for one or more of the trace layers, and wherein each via, upon manufacture, comprises a stub portion not necessary for the signal pathway; and \n wherein the bottom of the PCB is milled to form a variable-depth cavity in the bottom of the PCB, and wherein one or more of the depths of the variable-depth cavity are selected to remove the stub portions of the plurality of vias and to remove the PCB material between the stub portions, and wherein a capacitor is connected to the bottom of the PCB within the variable-depth cavity.
