Questions and Answers

Why is it nearly impossible to solder metals without addressing the oxide problem?

Oxides are thermally insulating, hindering the melting of metals. (correct)

Oxides are electrically insulating, causing a short circuit.

Oxides release toxic fumes when heated.

Metals become brittle in the presence of oxides.

What is the role of Solder Flux during soldering?

Act as a lubricant for the soldering process.

Strengthen the bond between the metals.

Enhance the electrical conductivity of the metals.

Breakdown metal oxides on the surfaces to be soldered. (correct)

Why is it important to work quickly once the oxides are broken down during soldering?

Oxides re-form rapidly once broken down. (correct)

The flux becomes corrosive if left on for too long.

Excessive heat is generated once the oxides are removed.

The metals become more susceptible to rusting.

How do oxides impact the melting point of metals during soldering?

Raise the melting point by acting as thermal insulators. Signup and view all the answers
