I'm not sure what you mean by "when the archwitch is full heart", but here's my answer based upon how I've interpreted your question:

Archwitch hearts are gained by chance whenever you encounter the AW. Each time you find an AW, there is a small chance that you will gain 1/4 of a heart towards only that AW. For AW, there are 4 hearts, and FAW 5, if I remember correctly. Once all 4 or all 5 of those hearts are filled up, then you get a guaranteed drop of that card.

So basically, AW hearts are not based upon who kills or tags the FAW, and you can't really "receive any hearts", as they aren't given in chest drops and only increase when you encounter a F/AW. It is entirely possible to fill up the whole heart meter without ever dealing damage to any F/AW you find, but that would mean that each time you find a F/AW you have to wait for its timer to expire and then find another one.
