FCC Technician Exam Question Of The Day (T7D08)

Q) Which of the following types of solder is best for radio and electronic use?

A) Rosin-core solder

NJ2X Notes:
Don't use plumber's or acid core solder for electronics or electrical applications.  Rosin-core solder will work very well and will not damage your circuit.  The Rosin Flux Core cleans the oxide off the foil and components being soldered which aids in wetting and creating a good electrical and mechanical joint.
