Why I Stopped Making Last-minute PCB Changes Before Ordering

There was a time when I would make "just one more small change" right before exporting the manufacturing files. Most of the changes were minor, a moved connector, a renamed label, or a slightly different trace.

The problem was that those last-minute edits often meant exporting the Gerber, BOM, and CPL files all over again. It was easy to forget one file and end up uploading mismatched revisions.

Now I have a simple rule: once the design passes the final review, I avoid making any more changes unless they're necessary. If I do need to modify the PCB, I regenerate every manufacturing file from the latest revision.

It takes a little longer, but it gives me much more confidence before placing the order.
