Easy with big 20 pin chips and bare board. Not so easy with tiny (5 mm square?) 8 pin ones on a populated board. B-)
Putting that video with my limited experience of hand soldering SMD you do need the fine solder and flux pen. Tacking down just a single corner is good but positioning the tiny filter chips with a finger is really tricky and easily painfull, bit of clear sticky tape works much better. Good eyesight, lots of light and a good magnifier are also useful. I doubt many have access to stereoscopic digital microscopes...
Oh and thanks (I think?) for reminding me I've wanted to build a nixie tube clock since the 1970's...
