I figured out how to ruin a Nano today. I bought three a while ago that needed the pin headers soldered on. I soldered on up a few months ago and everything was fine. Today I decided to solder another one for a project. The soldering wasn't the best job but it was passable. So I went to load up a sk…

Have you got any desoldering braid ?

Show us good images of the soldering. Buy some liquid soldering flux, comes in a pen too. [image] [image]

[image] UKHeliBob: Have you got any desoldering braid ? No but I was wishing I did when I was trying to get the solder off. I need to get some and see if I can save the Nano [image] LarryD: Show us good images of the soldering. The amount of solder left on the pins is so small I can b…

[image] Share tips you have come across General Electronics When using an ‘soldering iron’ along with Solder Wick to remove excess solder, there is a good chance you will damage or lift PCB pads. Ideally you want to place as little pressure on the wick and solder joint as…

Just put a little paste/liquid flux on it and reflow it gently with the iron. A little pull back away from the IC with the tip, will usually clear away the blobs that are shorting the pins. Start close to the IC and sweep gently down and away. It may be that you don't have to actually remove any so…

Share tips you have come across use a ‘hot air wand’ instead of an iron [image] anon57585045: Just put a little paste/liquid flux on it and reflow it gently Good ideas. I have a soldering station with a heat gun. I could combine it with the paste to see if I can flow the solder out.

Heat gun is overkill and will stress nearby components without need. Also the blobs won't go away with a heat gun - they will only cling even better to the pins. I've removed shorts like those ones, hundreds, maybe thousands of times with the iron. The secret is - when the iron is clean, it attrac…

First invest in some liquid flux.

[image] anon57585045: and will stress nearby components without need Yes. If you have Aluminum tape components can be shield from heat. Cannot stress enough the OP needs flux.

Awesome, I got the Nano to work. The soldering tip on the soldering station iron is long and really thin, pointy. I painted some paste flux on the pins with the extra solder and used the very tip of the tip. I made sure it was really clean and almost no solder on it. The tip pulled the extra solder …
