Hi,
Unfortunately, the spring of one of the battery holders separated from the PCB. Can I buy another holder or how can I attach it to the PCB?
Thank you!
Can you just re-solder it in place? It doesn’t look like it would be hard if you have the tools.
Agreed with Mandrake50, you will need to just re-solder it back in place.
Should be fairly simple since you can place the spring back into the solder where it separated, add some flux, then heat the solder until it starts melting.
You could also take the battery holder apart in order to have better access to solder the spring.
Thank you very much for your help! I would also like to ask if I can heat the solder material as well, will it not be a problem? Or should I just heat the spring?
Thank you very much for your help! Should I just heat the soldering material, or do I need the spring? I don’t want anything to go wrong.!
I would get some solder and flux paste.
Put some flux paste on the area. Smother it in paste.
Put the spring back where it is supposed to go. Line it up with the old solder.
Heat up a bit of new solder on the tip of a soldering iron. Then put the tip on the spring, pushing it against the board. Feed some more solder wire into the tip and spring.
The flux should evaporate. It may greatly help with getting the solder to work… If there’s excess left over, you could spray the are with isopropyl alcohol and wipe off any excess.
Some more info:
With the spring in place, just heat the bottom of the spring where the solder is until it starts melting. Then do the same with the other spot(s) of solder.
If it appears that there’s not enough solder to hold the spring securely, you should add more solder. Perhaps not enough solder was used initially and that’s what caused the spring to come loose.
I soldered it, but unfortunately it turned out pretty ugly. it holds the spring in place, do you think I can use the lamp this way? I used such a flux.
Thank you!
It is probably fine, but it looks like you didn’t heat enough. Those globs are caused when the solder doesn’t flow well. This is because the material did not get hot enough to let the solder flow properly. The very bottom of the spring should be heated enough to heat the board below it as well. Then the solder just kind of “sheets” and melts into solder on the board under the spring.
What you did will probably work, but it will not be the strongest possible joint. BTW, the springs I have fixed usually are soldered in more than one place. Sometimes all the way around the base. If you can solder it in more than one place, that would be better. It will be better physically and may reduce resistance a bit.
Again, as long as it does not come out again, it should work OK. Pressure from the battery will keep it in contact with the board.
