Usage

• Setup:
  • Heat soldering iron to 600–700°F (315–370°C).
  • Tin the iron tip with a thin solder layer.
  • Apply solder to clean, fluxed surfaces (e.g., PCB pads or wires).
  • Hold components together until solder cools (2–3 seconds).
• Testing:
  • Inspect joints for a shiny, smooth appearance.
  • Test circuit continuity with a multimeter.
  • Verify functionality (e.g., LED lights up in a test circuit).
  • Ensure no solder bridges between pins.
• Troubleshooting:
  • Weak joints: Clean surfaces with isopropyl alcohol; reapply solder.
  • Solder not flowing: Check iron temperature; ensure tip is tinned.
  • Cold joints: Reheat the joint and add fresh solder for a smooth finish.
• Caution:
  • Work in a well-ventilated area to avoid inhaling fumes.
  • Wash hands after handling due to lead content.
  • Avoid touching hot iron or solder; use a stand.
  • Keep away from children to prevent ingestion.
  • Store in a dry place to prevent oxidation.
