You know, the flux paste from RadioShack?
I was wondering if it is conductive in its melted form.

Ok, thanksHemlock Mike said:Most solder flux is conductive under "proper" conditions.
The old stand-by Kester 44 is a chloride which is a salt and can be conductive if the petrolium jelly is removed leaving the flux and in high humidity. This is more corrosive than conductive.
We are dealing here with mostly low impedance circuits and small leakage <~10K ohms is not a factor unless you are on the gate of a Mosfet.
I wash with bipolar solvent to try to get both elements of the flux and carrier. Using basic flux core solder --- no problem --- unless you are in extreme environments.

No, mine just taste wierd.lasersbee said:Just stay away from the Acid flux used for sheet metal soldering... it even
comes in Acid core solder format... if you want to know if your flux is Acid...
put a small amount on the tip of your tongue... if it burns slightly.....
Yup... it's Acid Flux..

Oh, ok...Hemlock Mike said:That "good" smell is rosin -- pine tree sap which contains abedic acid. That is mild stuff and has been used for many years.
DON'T taste that stuff -- it contains lead (Pb) bad for you.

Really? :-?ElektroFreak said:Flux is non-conductive (an insulator) by itself. Too much will ruin a connection..
Yea, i knew that the actual solder was the conducter...ElektroFreak said:The tin/lead mixture is the conductor. Rosin flux is just tree sap.. non-conductive. Acid core solder also has a non-conductive flux. Acids are much more of an insulator than the surrounding metal. Flux merely helps the solder flow, and in the case of acid-core, prepares the surface for soldering by cutting through any corrosion/oxidation, I believe, although I never use it myself..
