The biggest mistake with soldering that people make is to put way too much
solder on - then mess it up worse trying to get rid of it. That, and
overheating the wire and maybe damaging the component they are trying to
solder. So here's a couple of tips. Please read through before doing the
soldering!
Get everything ready first! Cleaning stuff (wire wool, light grade
sandpaper), tools (e.g. soldering iron, solder, flux, long nose pliers or
tweezers, torch [if needed], tiny soldering vacuum cleaner [if you have one
lol] etc.)
IMPORTANT! Try to angle the camera with its exposed innards such that no
drops of solder will be likely to fall into its workings! Solder can and
does drip when melted! It also conducts current! So try and use something to
hold the camera steady and in an angled position such that any drops of
solder are likely to fall away or out of the camera rather than in it!
Strip of sufficient insulation (if any) from the ends of the wires taking
care not to pull the wires out or break the wires (or pull the whole
insulation off). Then clean the wire ends you are trying to solder (makes
the solder take better - solder just will not "take" to dirty parts or
wires!). A bit of wire wool is good for doing this. '
Use a small, thin soldering iron tip - many soldering irons have
interchangeable tips and come with a selection of tips.
Clean the tip of the soldering iron. Heat the tip. You might want to grip
the wires with a pair of long nose pliers - which will help dissipate excess
heat and stop you burning the tips of your fingers maybe. Using the tip of
the soldering iron, very lightly 'tin' the wires with just a touch of solder
- just a touch with the tip along the exposed wires should suffice! When the
solder has cooled, twist the ends of the wires together if possible.
Clean the tip of the iron! (use the wire wool again - or light grade
sandpaper or emery paper). Then let it get hot again - then just apply just
a **little** solder - the melted solder should barely cover the tip. If you
get a blob of solder on it or the solder starts running, you've got too
much, so shake off the excess solder before doing the soldering - if in
doubt, clean the tip and start again.
Again, you might want to grip the wires with a pair of long nose pliers -
which will help dissipate excess heat and stop you burning the tips of your
fingers maybe.
When you have just enough solder on the tip of the iron to lightly barely
cover the tip, apply the solder (quickly) - it doesn't take much - solder or
time. Don't keep the tip in contact with the wire for long as that heats up
the wire and can damage components and/or make soldering more difficult -
just a touch with the tip should suffice!
When you have moved the tip away from the join, wait a couple of secs for
the solder to cool before testing the join. Hopefully, you should then have
a good clean join with no unsightly blobs of solder and which should be
strong enough to hold the wires together if they aren't stressed. I'm
assuming there isn't a chance of twisting the ends of the wires together
prior to soldering. If you can, do that (being careful not to pull and break
the wires), then apply just a tiny bit of solder to keep them together and
stop them from untwisting and pulling apart. When the solder has fully
cooled and you are happy with the join, if you can, put a piece of insulting
tape around the join - this will help to hold the wires together, and
insulate them from touching any metallic parts in the camera and help stop
them from untwisting and coming loose.
This has been a kind of general help to soldering two small lengths of thin
wires together - and I've made a number of assumptions (not having soldered
anything inside a camera before).
