70% to passWhich type of flux should be used when soldering electrical wire connections for electronic components on printed circuit boards?
ASolid flux
BSilver flux
CRosin flux
DAcid flux
AI Explanation
The correct answer is C) Rosin flux. Rosin flux is the recommended type of flux to use when soldering electrical wire connections for electronic components on printed circuit boards. Rosin flux is a non-corrosive, mild flux that helps remove oxidation and promotes good wetting of the solder to the metal surfaces, which is essential for reliable electrical connections in electronics. The other answer choices are not suitable for this application. Solid flux is too aggressive and can leave corrosive residues, silver flux is intended for soldering silver components, and acid flux is also too aggressive and can damage electronic components.
