Hi, the picture below shows the back of a miniature loudspeaker from an in-ear earphone.
There have been two pads for soldering electrical contacts on it. On each pad I was able to solder a wire on. But it took no 30sec. and one pad broke off.
So what you see on the picture now is:
- left: the pad which did not broke of
- right: at this place was a pad the same size as on the left side. But now, after it broke of, all what remains is a very, very, very tiny spot where the broken off pad was connected with (assumption)
- top: the tip of a needle, to give you an impression how small all this is.
For me, it looks like the only possibility to solder anything on the tiny spot would be with a laser and a microscope (both I don't have). Any ideas, how I could solder this, with an hobbiest standard equipment (normal soldering iron)?
Thanks!
