second opinion on heat bed solder joint
« on: June 22, 2013, 05:46:13 PM »
Hello there!
I'd like a second opinion about this solder joint, as a little bit of solder has flowed onto the negative terminal. I'm pretty sure that this is an error.

Is it time to whip out the solder braid?
Also, sorry about my abysmal phone camera/photography skills. :)

I decided to clean it up. Some pictures on jits build confirm my suspicions  :D

I remember seeing at least one board (maybe yours) that had a solder jumper like that, and I checked it at the time to make sure it wasn't a problem. There is a pcb trace right under that solder jumper making the same connection, so it's not a problem. If you do try to clean up the solder, be sure not to cut the trace under it in the process. If you do, the indicator LED on the board won't work.

Yeah I found that trace.  :)

I exposed it but didn't cut it. I had to file the last little bit of flow away. I was thinking I might try to put some low viscosity sealant of sort over it. I'll run it before hand to make sure I didn't cut the trace (wish me luck on that one :P)

Update:

It turns out I didn't expose the trace, it was just the copper color of the pads being exposed from my file. The LED works, and the two pads are no longer connected.
