Which item is not listed as part of 2M repair materials?

• A. Flux
• B. Isopropyl Alcohol
• C. UV-curable resin
• D. Solder-tin alloy 63/37

Answer: (C)

In this topic, the materials focus on what’s used for a quick solder-based repair: flux is used to remove oxidation and help solder flow, isopropyl alcohol cleans away flux residues and contaminants, and the solder-tin alloy 63/37 provides the actual metal join. A UV-curable resin, on the other hand, is an adhesive/potting material that cures with UV light, which is not part of the rapid solder repair process. Therefore, UV-curable resin is not listed as part of 2M repair materials.
