Optimize Existing PCB Layout & Components

I have an already-functioning PCB that now needs a refresh focused squarely on better performance through lower power consumption. Concretely, this involves two intertwined tasks: swapping out a handful of components for more efficient equivalents and re-working sections of the board layout so that routing, grounding and thermal paths support the new parts and keep overall draw down.

The core objective is improving performance; cost reduction or extra features would be nice side effects, but they are not the target this round. I’m expecting practical engineering choices—component selection, placement tweaks, trace width/length optimisation, maybe power-plane adjustments—that measurably cut current without compromising existing functionality.

Preferred tools are Altium Designer or KiCad (I can import from Eagle if that’s what you use). Whatever CAD platform you select, please give me the native project, updated schematic, Gerbers and a refreshed BOM so I can run a quick prototype straight after hand-off. I’ll provide the current design files, performance logs and space constraints once we start.

If this sounds like your kind of board-level challenge, let’s talk through the particulars and timelines.
