If you regularly photograph relatively flat things and want a consistent look, just get a copy stand. No futzing with a mirror to align the camera every time, just mount it, drop the objects on the stand's floor, and boom there you go. You'll never want to use a tripod again for that. The only issue is that typical copy stands use the same hardware as enlargers, so their columns are usually fairly short; maybe 50-60 cm for the normal size, and around a meter for "large enlagers". This limits you to short 60mm macros for floor-covering subjects, and reserves medium (~105mm) macros for approximately Eurocard-sized objects. You can get long columns, but they're a specialty item, and now the enlarger/copy stand has to go on the floor. For PCBs a light table makes them look nifty, but it's fairly useless for multi-layer ones beyond showing that they're multi-layer. Most have inner power planes anyway. (The issue with short macros for things that aren't actually flat is that you get perspective distortion because you're close to the objects; long 150-200 mm macros get you closer to an isometric view)
