🔍 Key Concepts

• Effect of excessive heat on printed circuit board (PCB) traces/foil • How soldering heat is transferred from the iron tip to pads and components • Difference between proper solder joint appearance and damage to the board

💭 Think About

• When a soldering iron is too hot or applied for too long, what physically happens to the thin copper foil that forms the PCB traces? • Which choice describes a realistic failure mode you might actually see after overheating a pad or trace during soldering or desoldering? • Look for the option that focuses on local damage to connections rather than overall board appearance or unusual solder properties.

✅ Before You Answer

• Identify which option mentions damage to the foil/traces or pads on the PCB. • Eliminate any answers that describe effects that are unlikely or not typical results of brief overheating with a soldering iron (e.g., unusual solder color requirements). • Focus on the consequence that would most directly affect electrical continuity and reliability of the circuit.

Question 1 of 20

Why is it a poor practice to use a high wattage soldering iron when soldering or desoldering components on a printed circuit board?

The circuit board will blister and warp.

The foil wire may become loose and separate from the circuit board.

The circuit board material may become brittle.

The solder needs to be kept to a dull heat dissipating finish.
