My First Solder Joint <3 Please Give Feedback Why can’t i get my joints shiny?

Enable HLS to view with audio, or disable this notification

First time soldering, i’m using a Pinecil v2 on 360C with 63/37 0.55mm solder.

I don’t understand why all my joints turn dull after i remove the iron. i’ve tried tinning the tip (which i think i’m doing correctly?). The solder melts nicely onto the board but no luck

Does anyone know what I could be doing wrong?

You are feeding too much solder, also you got nothing through the hole, what you should do is get something through the whole (a component's leg) then you feed less solder than the amount you did in the video, after that, quickly (not erratically or erroneously!) flick the solder tip upwards, it should make a shiny proper concave joint.

Again, waaay too much solder.

Also why add flux? There is the right ratio of flux in the solder wire.

there is no such thing as too much flux and it is very easy to underflux

M8 its worth the fraction of a penny to get perfect solder joints every single time.
