Electronic Solder Technique

Introduction to Soldering

Soldering is a process in which two or more metal items are joined together by melting and then flowing a filler metal into the joint—the filler metal having a relatively low melting point.

• Soldering is used to form a permanent connection between electronic components.

• The metal to be soldered is heated with a soldering iron and then solder is melted into the connection.

• Only the solder melts, not the parts that are being soldered.

• Solder is a metallic "glue" that holds the parts together and forms a connection that allows electrical current to flow.
