Photo, pins are slightly off the pads but within QA tolerances. I always aim for best practice.
I use a powerful magnifying glass as sometimes pins are too close for probes.
Sometimes excess flux needs cleaning off to see properly.
Fluxite - that's for plumbing, isn't it, at least mine is. The flux is acidic, not wise for pcb assembly.
Yes, the tip is the secret sauce (plus the flux). With a standard tip it doesn't work. The concave "hole" in the bevel tip allows to add and remove solder at will in seconds. It's so easy it feels like cheating.
I recommend KSGER soldering iron from aliexpress, with BCM2/BCM3 tip.

I wrote chisel, I meant bevel.Yep, that's exactly mine too. Fry's Fluxite. Bought it in 1972, and still in use, but never for PCB work.
Well it works great for PCB work, and you clean the excess off afterwards, so what's the problem?
I'm about sick of this forum, trying to get help and advice is like getting blood from a stone but there are plenty of people just dying to point out any tiny little thing you might not be doing just right.

Yeah +1 the nitpickers are annoying.
That doesn't change the fact zinc chloride flux will destroy your board if not thoroughly cleaned.
Yeah, I don't use the Fluxite often and always clean any residue off with isopropyl.
I'll give you an example of the imbalance between negativity and helpfulness - at least 5 times in the last couple of weeks people have chimed in to tell me the 7805 shouldn't be used in audio in 2021. However, not one of them, when asked, has a single word to say about what I should use INSTEAD of the 7805.
This is not helpful.

7805 isn't special snowflake enough, too cheap, not anointed...
Modern LDOs have much lower dropout and lower idle current, but PSRR, noise and especially transient response are not necessarily better (and often worse) than the old fossil 7805... unless you pick a really good one... there is no incentive to develop a cheap mass produced high performance regulator because everyone uses switchers anyway.

For giggles, ask for "measurements to back it up" , this never fails.
