 |

Greetings,
I was inspecting a new electronic device that wasn't working and found a solder bridge between 2 of the pins on an SMT chip.
I'm looking for an easy way to remove it. My plan is to use a hot needle to touch it and maybe I can sweep or blow it away. I'm open to suggestions, keeping in mind I have no equipment for working on SMT components.

Thanks in advance for any suggestions.

Do you heat and then drag the wick, or put the wick on the solder and then heat the whole thing? Put a little flux on the wick?
Thanks for the help.

Regular soldering iron and good quality solder braid/wick. Optionally flux.
In a pinch you can do it with just the iron - melt a ball of solder on the end of the iron and drag it across the pins at the right speed, the surface tension will pull out the bridge. Flux helps.

Just drag the hot tip between the bridged terminals, just slow enough to melt the solder.

Standard reflow soldering profiles peak around 230 deg C, and that should be plenty to fix your bridge. Just clean and tin your tip, then drag it across the bridged pins, pulling the bridge away. If there's a lot of excess solder there, you may need solder wick, but be careful how long you dwell with the iron against the component. As a previous post suggested, a little flux on the wick will help to draw away the excess solder.

The wick usually comes with some flux impregnated in it (at least the
better wicks do) but an extra dab doesn't hurt. I usually put the
wick on the solder bridge and then heat the whole thing. Sometimes
adding a small amount of solder helps wet out the iron and the wick
for better heat transfer.
Don't be scared of SMT soldering and rework, it takes a little
practice to get good but it's much easier than you think.

The wick probably isn't necessary. Unless there's *way* too much solder
on the two pads, just dragging the (fine point) hot iron between them
will usually clear the bridge. It's certainly worth a shot before
risking de-soldering both pins with the wick & being forced to re-solder.

Greetings,
Well... It's confession time. After 2 hours of tentative poking, heating, fluxing, wiping and inspecting it turned out that the "solder bridge" was actually a pad that 2 leads on the chip were supposed to share. That little detail aside, I learned a great deal about SMT soldering and rework.
Thanks to everyone who offered guidance.
