Building hardware usually follows five stages: define what it should do, design the schematic, lay out the PCB, manufacture/assemble it, then bring it up and debug it. The key expectation is iteration: Rev 1 commonly has a footprint, power, wiring, or mechanical issue. Planning for two or three board revisions makes that normal engineering rather than a surprise.

Flux can compress schematic design, layout, checks, and revisions, but not fabrication and shipping. A simple board may take days to a couple of weeks to design; RF, multi-rail power, or high-speed designs can take several weeks. Each physical revision can add roughly a couple of weeks for manufacturing and assembly, so waiting and debugging often dominate the schedule.
