question regarding soldering Cu ribbon..

[es347]

I am soldering 0.012 110C Cu ribbon and have a question. The solder flows nicely but when finished, the ribbon is discolored...the typical bluish color. My question is does this in any way impact the electrical properties of the Cu ribbon. I know it can become brittle and lose life but my concern is what may be happening to the conductivity, resistance, et al. Thanks in advance.

Waht are you using as a heat source ? A low wattage soldering iron specifically for eletronic soldering is best. It sounds as if you might be applying too much heat, however it should not impact the electrical properties.

Make sure you have a good physical connection before soldering and the resulting solder joint should be shiney. If you use flux, after soldering remove excess or the copper will turn green. Too much heat on flux will burn it and turn it black.

Good Luck!
