eagleswind2 Posted November 28, 2015 Author Report Share Posted November 28, 2015 I have a DNA 40 chip that has solder going from one connection to another. How do I clean off the old solder in between the two connections? Nothing I've tried seems to work. Link to comment Share on other sites More sharing options...
VapingBad Posted November 28, 2015 Report Share Posted November 28, 2015 A solder sucker or de-soldering ribbon, flux will help. If it is one of the battery and charger connection it would not cause a problem as they are connected anyway. Link to comment Share on other sites More sharing options...
eagleswind2 Posted November 29, 2015 Author Report Share Posted November 29, 2015 A solder sucker didn't work and I have to order the de-soldering wick so I haven't tried that yet. It is both the battery pos and neg terminals touching the usb charging terminals. Link to comment Share on other sites More sharing options...
Dampmaskin Posted November 29, 2015 Report Share Posted November 29, 2015 Have you checked out EEVblog's soldering tutorials? They are great, and have lots of tips and tricks for soldering everything from heatsinks to battery cables to surface mounted components. Link to comment Share on other sites More sharing options...
