🔍 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.
