2. Point-to-point construction - Wikipedia

   en.wikipedia.org/wiki/Point-to-point_construction

   The crucial invention was to apply soldering to electrical assembly. In soldering, an alloy of tin and lead (and/or other metals), known as solder, is melted and adheres to other, nonmolten metals, such as copper or tinned steel. Solder makes a strong electrical and mechanical connection.

3. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   Desoldering a contact from a wire. Soldering (US: / ˈ s ɒ d ər ɪ ŋ /; UK: / ˈ s oʊ l d ər ɪ ŋ /) is a process of joining two metal surfaces together using a filler metal called solder. The soldering process involves heating the surfaces to be joined and melting the solder, which is then allowed to cool and solidify, creating a strong ...

4. Soldering iron - Wikipedia

   en.wikipedia.org/wiki/Soldering_iron

   Solder melts at approximately 185 °C (365 °F). Soldering irons are designed to reach a temperature range of 200 to 480 °C (392 to 896 °F). [1] Soldering irons are most often used for installation, repairs, and limited production work in electronics assembly. High-volume production lines use other soldering methods. [2]

6. Selective soldering - Wikipedia

   en.wikipedia.org/wiki/Selective_soldering

   Selective soldering machine. Selective soldering is the process of selectively soldering components to printed circuit boards and molded modules that could be damaged by the heat of a reflow oven or wave soldering in a traditional surface-mount technology (SMT) or through-hole technology assembly processes. This usually follows an SMT oven ...

7. Soldering gun - Wikipedia

   en.wikipedia.org/wiki/Soldering_gun

   Soldering gun Soldering gun's parts Spool of solder. 1.6mm. A soldering gun is an approximately pistol-shaped, electrically powered tool for soldering metals using tin-based solder to achieve a strong mechanical bond with good electrical contact. The tool has a trigger-style switch so it can be easily operated with one hand.
