Which item is used as a tool to apply solder during 2M repair?

• A. Tooth pick
• B. Isopropyl Alcohol
• C. Paper towel
• D. Flux

Answer: (A)

The essential idea is precise placement of solder in tight spaces during delicate repair work. A tooth pick gives you a tiny, controllable tip that lets you place a small amount of solder exactly where you want it on a joint or pad. With the iron warming the joint, the solder on the tooth pick can be touched to the joint, and the heat draws the solder into the joint cleanly, helping to form a reliable connection without risking bridged traces or excess solder. Cleaning and prep tools like isopropyl alcohol or paper towels handle cleanup, and flux helps the solder flow, but they aren’t used to deposit solder itself. Using a tooth pick for the actual solder placement is the practical way to achieve precision in 2M repairs.
