What are we talking, TQFP-0.4mm or? QFN?
STTC-036 is what I did use. Its not as good for QFN though.
On the T12 I prefer to use T12-KU, a small knife tip, way better for QFN touch up.
The closest I can find is maybe
M7DS035H, but, the end does not come to a sharp point as the T12-KU does.
The bevel stuff might be ok too, but, 0.016"/0.4mm is crazy small, to me those small tips are almost useless unless its for modwiring. I would want say 2-3mm bevel at least for soldering.
