Hi there fellow people,
I was building an Aurora Sofle_v2 and I may have screwed things up. I melted one of the RGBs with the soldering iron and in the process of trying to remove it the solder pad was removed as well
After that I tried to “fix” it a handful of times, and now I believe that the connectors might be gone =(
Is there a way for me to salvage this RGB? (Or perhaps to link the previous one with the following one on the chain, so at least it works for the others)
I was thinking of connecting things using cables, is this an option?
Update: Bodge wiring worked! I got some spare cable pieces I had laying around and soldered it to the board The back doesn’t look pretty, but at least it’s lighting up (except the last RGB where I accidentally soldered two pins together, after this I’m not going through the troubles to fix it)
If you have lifted the pad off, the only way to fix it is to use a bodge wire. You should be able to run a wire between the broken pad and the previous functional one in the network. If you look up bodge wire you’ll see this is a pretty standard practice, especially when prototyping PCBs.
Solder to the the far point first, lay down the wire, glue it in place, then solder the other end of the wire to the component.
Or one can scrape off the enamel coat from the trace, solder the bodge wire to the trace, and then tack it to the component.
Be sure to get the parts thoroughly wet with solder to cover any exposed copper. It will prevent corrosion.
Hmmm, you mean a special wire for soldering right? I was initially thinking in soldering some scraps from a copper cable I had laying around but quickly realized it was not going to work
You normally just use very tiny wire. Anything is technically fine but certain types make it easier. Generally something solid core, 30-40AWG. Some people have a specific preference for Kynar or Teflon but there’s no hard and fast rules.
I see, the tiny wire I had was the problem then, it has multiple filaments that kept going off
I’ll try this one today!
