Building a custom PCB typically follows five phases: define requirements, design the schematic, lay out the PCB, manufacture/assemble it, then bring it up and debug it. The key expectation is iteration: Rev 1 usually reveals something to fix—a footprint, power issue, missing pull-up, or mechanical mismatch. Planning for 2–3 revisions makes that normal engineering rather than a surprise.
A simple board may take days to a couple of weeks to design, while power-heavy, RF, or high-speed designs can take several weeks. Manufacturing and shipping often add roughly a couple of weeks per revision, so waiting and debugging usually dominate the calendar. Flux can accelerate design, checks, layout, and revisions, but not fabrication lead time.
