    Soldering tips needed.

    I'm about to assemble a regulator circuit and I'm in need of tips since my soldering skills aren't great. I have a 23W soldering iron with an unscrewable single point tip. It's kind of a mess with burnt on stuff and excess solder right now so I'm probably going to try and find a replacement tip (although ideas on how clean it are welcome).

    What I tend to find is that the solder stays on the soldering iron and/or seems to prefer collecting onto that even if I'm trying to apply the solder directly to the intended joint. And once it's on there I struggle to get it where I want until (often) it splurges all over the destinaton and screws up the joint.

    The circuit I'll be building will have many closely spaced joints and I can't afford the above to happen at all. I've bought some new rosin core solder since I've no idea of the quality of the old stuff (it's very old) and a new stand with foam cleaning bit (I've misplaced mine) to help.

    Any other suggestions - would a better soldering iron help? I think the one I've got is cheap.

    sounds like someones been painting the solder on...

    and as for cleaning the tip, you heat the iron up and wipe it off on the wet sponge....

    I've only got common sense advice... dunno if others have got better ideas:

    get a better iron w/ a removable tip.

    Having a well-tinned tip is probably one of the most important aspects of soldering; at least thats what i've learned. I clean mine constantly while i'm soldering w/ a wet sponge. Usually, if you get any foreign material (wire sleeving, plastic, etc.) on it, its not worth using anymore.

    Your best bet for clean joints are to heat the parts and not the solder. If you mess up or have to resolder a sensitive part for any reason, make sure you let it cool down for a few minutes first, otherwise you'll risk damaging it.

    Most importantly, you just gotta be patient.

    All this seems tedious, but trust me, it'll save you lots of time and money in the long run.

    I think the tip is probably dead then. A wet sponge just isn't doing much for it these days and I've definitely got wire sleeve plastic on it more than once .

    I bought a clip on 'heat sink' thingy to help guard against damaging the parts. Most soldering I've done the only thing I've had to worry about damaging has been my fingers and the plastic insulation near the end of the wire I'm soldering. Needless to say, I've melted both many times!

    The parts I'm soldering are rated to 125 C so I think I'm unlikely to damage them whilst soldering unless I'm careless and don't let them cool between passes.

    So, sounds like I need to track down a new tip or a new iron if I can't find that. Any recommendations if I get a new iron - I'll probably be getting it from Radio Shack for convenience.

    By 'well tinned tip', do you mean the soldering iron tip should have a coat of solder on it?

    the heatsink helps... If you need one, get a desoldering tool or braid as well. Those tend to come in handy.

    For all the sensitive work, i find that a 15w iron is best. You don't need much for circuit boards and high awg wire.

    By 'well-tinned,' i mean the fresh coating that the tip comes w/ when its new. This tip is still in good enough condition to keep foreign crap off your joints and will allow you to do your jobs much quicker since the heat will transfer faster and more evenly, which is important. You can keep it clean just by being careful with it.

    Oh yeah, here's a guide I came across which has good info. Its not geared towards sensitive electronics, but there are good general tips in there.

    Good luck!
