Actually I have two problems, but this one is most annoying:
I have like 10 wires I want to solder to the pins of a pin header (2.54 mm distance apart).
Initially I kept like 5 mm of the end of each wire noninsulated, to be able to solder it to the pin. However, I found out it's quite a lot, since two adjecent wires may touch each other eventually.
Now I keep the noninsulated distance just a few mm, but I prefer not to redo the wires I already did (some of them are not on pin wires, but on components directly and it would get messy removing the solder).
How can I 'fix' this. What I could come up with:
- Of course making the non insulated ends very small.
- Putting heat shrink tube around the wire before soldering and slide it as much as possible to the end and heat it. Quite some extra work though. Never tried heat shrink tubing, so maybe even the solder might get ruined?
- Sticking tape in between/over it, but the tape might get off later.
I wonder if there are better solutions.
Another problem I have, is that I didn't make the most beautiful soldering joints from some wires to some components (Hi Link AC/DC converters). They have short pins only and I'm a bit weary to remove the solder. However, I had already twice that when I put 220-250V on it, the wire broke lose from the component. Probably a cold solder connection? And what to do (probably redo the soldering?)
(sorry for not having pictures, the 'project' is not next to me now).
