CFX soldering oops

[mrlemon]

Hello from soggy Seattle.

I don't see a thread titled Asking For a Friend, so ...

This is for the Wise Ones Of the Forum.

My, er, friend accidentally bridged the Main negative pad to the metal USB housing on a CFX, and attempts to remove the bridge using copper braid and a solder syringe have failed. The solder has slumped into a difficult-to-reach spot close to the board. The plastic bits inside the micro-SD housing just below are at risk, and that region of the board itself is looking kinda toasty from the attempts at removal.

Two questions:
1. I'm assuming this condition is fatal and the bridge must be removed. Is that correct?
2. If it's fatal to board operation, any other suggestions as to a removal technique?

I'll post a pic if requested. Our power is out right now so it may be a while.

Thanks!

LOL. “A friend”, huh? I forwarded this to the top. I think I know the answer to that, but I’ll let him chime in to verify before I say anything. I’ll let you know when I hear back or maybe you’ll hear from the top directly. ;)

Yeah, a good high quality close up will help. Top and bottom,

Thanks, as always, FJK.
I can always use this board as a practice piece, albeit an expensive one.

Yes, my imaginary friend makes mistakes often.
I thought I made a mistake once. But I was wrong.

I'll post pics as soon as I have some good light.

Worst comes to worst, I’ll have Chewbacca get in touch if it needs fixing.

That would be awesome, FJK! :p
Above and beyond, as they say.

Here's a pic of the blob:

Ok, that doesn’t look TOO Bad. The easiest way to deal with that is to take your soldering iron, hopefully, it’s a nice fine tip, make sure it is completely clean and hot and try to “divide” that blob, leaving the solder on the actual pad, and whatever little is left on the SD card reader shouldn’t be too bad. Get the blob molten and then start at the interior board side of the blob and come straight out to the end, and draw away whatever solder you can in one fairly quick motion.

Thanks, FJK!
I'll give it a try and report back.

Good news, if it’s just the one little blob you showed me, the Top says you’ll be fine.

Thanks, FJK, and thanks to Mr. Top, as well.
This forum is awesome.

I can't wait for my friend to make another mistake.

Try not to make a habit of it, I can’t get always get Erv’ to respond right away. 😉

Understood.

Mistake it is not, then. Happy accidents they are.
