Solder

Solder is a metal alloy that is used in the process of soldering, which is the process of joining two or more metal surfaces together using a filler material. Solder is melted and applied to the surfaces being joined, where it forms a strong and reliable connection when it cools and solidifies. Solder is commonly used in the manufacturing of electronic devices, such as circuit boards and connectors, and in other applications where metal components need to be joined together. Solder is available in a range of alloys, including lead-based and lead-free alloys, and in different forms, such as wire, paste, and preformed shapes. The type of solder and the soldering process used will depend on the specific application and the materials being joined. In addition to providing a strong and reliable connection, solder can also act as a thermal and electrical conductor, allowing heat and electricity to flow between the joined components. This can be important in applications where the soldered joint needs to be able to withstand high temperatures or high currents.
