Looking for reliable way to solder small (5mm) QFN parts on densely populated boards. Can this be done with manual tools and without optical alignment system? I am looking at a high end rework station for this type of work - ATCO rework station https://atco-us.com/products/item/1-at-gdp-smd-bga-placement-rework-stations . Not sure if its overkill or other suggestions will be helpful.
