Not true , flux is used in electronics in some instances.

From wiki, cause I'm too lazy:
Solder often comes pre-mixed with, or is used with,
flux, a reducing agent designed to help remove impurities (specifically
oxidised metals) from the points of contact to improve the electrical connection. For convenience, solder is often manufactured as a hollow tube and filled with flux. Most cold solder is soft enough to be rolled and packaged as a coil making for a convenient and compact solder/flux package. The two principal types of flux are acid flux, used for metal mending, and rosin flux, used in electronics, where the corrosiveness of the vapours that arise when acid flux is heated could damage components. Due to concerns over atmospheric pollution and hazardous waste disposal, the electronics industry has been gradually shifting from rosin flux to water-soluble flux, which can be removed with deionised water and detergent, instead of hydrocarbon solvents.
I didn't think anybody read these guides I wrote. I wrote these way back before ss.org existed, when I was slumming around on HC..
