SOLDERING WIRE

Soldering wire (also called solder) is a metal alloy wire used to join electrical components and wires together. When heated with a soldering iron, it melts and flows into the joint, then solidifies to form a strong electrical and mechanical connection.

Common Types of Soldering Wire

• Different solder wire types are used depending on the application:
• Lead-Free Solder (RoHS)
• Composition: Tin (Sn), Cpper (Cu), Silver (Ag)
• Example: Sn96.5 / Ag3.0 / Cu0.5
• Pros: Environmentally friendly, used in modern electronics
• Notes: Requires slightly higher heat than leaded solder

Leaded Solder

• Composition: Sn60 / Pb40 or Sn63 / Pb37
• Pros: Flows well, easy to work with
• Cons: Contains lead (toxic) — avoid touching and inhale fumes
