Tips on attaching wires to small points?

Anyone have tips on attaching wires from the contact points of a camera sensor? I was thinking of just getting a long ribbon wire, but it’s quite hard to find one the right size, and I’m scared to solder it because it is quite a small point. I’ve seen a couple where a camera has many a wire poking out, but can’t find much other than either soldering (which I’m afraid to do at such a small scale) or tape, and if tape, I gotta find some stickier electrical tape, because it doesn’t seem to stay attached.
