Information handling system interchangeable solder pads
An information handling system printed circuit board includes solder pads that accept footprint compatible integrated circuits, such as charger integrated circuits that provide power with different choke circuit supporting components. Solder pads for supporting components include first and second conductive areas sized to accept a first supporting component, each of the first and second conductive areas including an intervening non-conductive area that manages positioning of a smaller second supporting component at solder reflow.
1. An information handling system comprising:
a printed circuit board;
a processor coupled to the printed circuit board and operable to executed instructions that process information;
a memory coupled to the printed circuit board and interfaced with the processor, the memory operable to store the instructions and information;
first and second supporting integrated circuits sized to couple to the printed circuit board at a first set of plural solder pads, the first set of plural solder pads matching a footprint of both the first supporting integrated circuit and the second supporting integrated circuit; and
first and second supporting components sized to couple to the printed circuit board at a pair of supporting component solder pads placed to have spacing between each other, the first supporting component supporting operation of the first supporting integrated circuit, the second supporting component supporting operation of the second supporting integrated circuit;
wherein the printed circuit board is built by a selection of the first supporting integrated circuit and the first supporting component or the selection of the second supporting integrated circuit and the second supporting component, the pair of supporting component solder pads have a footprint of less than the footprint of the first supporting component and that includes an intervening non-conductive portion defined between the pair to limit solder reflow when the second supporting component couples to the printed circuit board to support the second supporting integrated circuit, the second supporting component having a footprint that fits within a boundary defined by the intervening non-conductive portion.
2. The information handling system of claim 1 wherein the first and second supporting integrated circuits comprise first and second charger integrated circuits.
3. The information handling system of claim 2 wherein the first and second supporting components comprise charger integrated circuits.

5. The information handling system of claim 3 wherein the first supporting components comprise a 0402 capacitor and the second supporting components comprise one or more 0201 capacitors.
6. The information handling system of claim 1 wherein:
the first supporting component has a footprint of first and second opposing rectangles;
the first supporting solder pads have opposing conductive surfaces, each of the opposing conductive surfaces including the intervening non-conductive portion; and
the second supporting component has a footprint of first and second opposing rectangles smaller than the first supporting footprint, each intervening non-conductive portion impeding solder reflow at a boundary of the second supporting component.
7. The information handling system of claim 6 wherein the first supporting solder pads comprise first and second sets of three overlapping rectangle shapes each having a size of substantially the second supporting component footprint first and second opposing rectangles.
8. The information handling system of claim 7 wherein one of the three overlapping rectangle shapes on each of the first supporting solder pad sets extends towards the other set of three overlapping rectangle shapes.
9. The information handling system of claim 7 wherein two of the three overlapping rectangle shapes on each of the first supporting solder pads sets extends towards the other set of three overlapping rectangle shapes.
