Method for circuit power delivery using posts through the PCB

Disclosed is a method for circuit power delivery using posts through the printed circuit board (PCB). Benefits include improved power performance.

Background

      Getting the power regulator close to the circuit with low inductance is problematic. High current levels can burn a circuit board. High current levels meet resistance and add inductance to the board. Conventionally, these problems are solved by using an external power supply and a flex cable with a connector that attaches to the edge of the circuit interposer.

      The conventional output connector includes an output connector housing, I/O flexible cable(s), and VCC/Gnd cables (see Figure 1). A flexible cable attaches to the power regulator. An output connector snaps onto the edge contacts on the circuit interposer.

      The top view of a conventional power pod output connector indicates the positions of a voltage regulator, flexible cable, and a connector (see Figure 2). The side view indicates the positions of a power pod case, an output board, a flexible cable, and a connector housing (see Figure 3).

      The ISO view of a processor substrate form factor indicates the positions of edge fingers for connector attachment (see Figure 4).

General description

              The disclosed method is circuit-power delivery using posts through the PCB. Circuit power is transferred from an electrical regulator by means of power posts through the circuit board.
