yea na fuck that switch is fucked

well, i did it, but i'm pretty bad at soldering

well only way to get better at it = do it more often

i never actually properly learned how, just from doing it very rarely. just heat that lead up and drop it on the pcb awkwardly

(don't do it that way)

heat the pad up

and then apply solder to the pad

i'll watch a video

what's a pad

anyway yea i'm doing it wrong

a pad is the exposed copper on a pcb

ah okay.

that explains why the solder doesn't stick to the pad

because i am not heating the pad

solder won't stick if it's not hot yeah

only the solder

okay

you can put a little bit of solder on the tip to make the heat transfer better

wow that's beautiful

your solder probably has some flux inside of it, which is the white smoke you see

it burns off quite quickly

if you apply it to your iron it burns off before you even get to the joint

I've burnt many boards not doing it properly

so you don't really want to see white smoke

because you want to apply the flux and not burn it off

no, the flux always burns off

you just want it to burn off in the right place

it cleans the joint

ok

oh so that's what flux is

i should buy some of this

white smoke is normal

all engineers I worked with just shove the iron into the flux

depends what kind of flux it is

you can use the flux for cleaning your tip too

everyone where i work uses liquid flux and applies it to the joint
