Today I finally learned to appreciate a flux pen!

...

Seeing how the joint reacted to the flux, heat, and solder really changed things. On previous practice sessions, I was finding that I had to paint around the joint to get it perfect.
it's a wonderful moment when it all 'clicks'

I was doing some SMD soldering just last night, and was actually having difficulty using the fine-tip and swapped to a fatter one and it literally magic-ed away the problems I was having. the fine tip just wasn't delivering enough heat and the flux pen took care of the rest.

Yes, it certainly is a wonderful moment when everything finally clicks together. Your guide gave me the confidence to start soldering projects and the support of the community is wonderful.

Hi abrugsch, great guide! When buying steel wool what grade would you recommend? Coarse or fine? I'm looking at this product; would it work? Thanks!

I don't think the fine household cleaning stuff would work well tbh (though I've never tried) as it's too fine and rusts... I could be wrong though! Might be worth a try as it's usually cheap enough and easy to find ;)
The coarser stuff tends to be brass or copper (in colour at any rate) and lasts quite a while.

That is some mighty fine soldering right there. Congrats!
Turn the board over and show the upskirt shot ;)

Lol here it is, not the best I've done but at least I think I can more than likely solder a RPi to an AIO without destroying it!

Yeah a bit of a mixed bag there but nothing terrible. If you get a flux pen you'd be able to clean those right up. It's mainly just too much solder with some very good looking joints mixed in

So I've got a couple of questions for ye all.
I've been practicing de-soldering old Network cards, and various PCB's from old TVs and radios.
And I've noticed that my solder sucker will get fouled up pretty quickly - once that happens it loses all ability to suck. So I've to take it apart and clean it and then I've been using copper grease (because it's what I have to hand) to reseal the seals against the tube.
Is this something that happens, or is my sucker shit? And if it is, what are you guys using for resealing it?

Secondly; and this is a shorter question, how the hell do you use solder braid, it seems to work sometimes and not others, randomly.
I've fluxed it and not fluxed it, heated and not heated it and I cannot figure that shit out.

Thanks guys for your help.

Desoldering is a bit of a black art... the sucker sounds normal but for me usually the tubes of sucked solder come out on subsequent presses of the plunger.

As for braid, well as it's copper it's also a really good heat sink... so you usually need extra heat to compensate for that, or pre warm the braid
