Solder (UK: / ˈ s ɒ l d ə, ˈ s ə ʊ l d ə /; [1] NA: / ˈ s ɒ d ər /) [2] is a fusible metal alloy used to create a permanent bond between metal workpieces. Solder is melted in order to wet the parts of the joint, where it adheres to and connects the pieces after cooling.
Soldering copper pipes using a propane torch and a lead-free solder. Solder is a metallic material that is used to connect metal workpieces. The choice of specific solder alloys depends on their melting point, chemical reactivity, mechanical properties, toxicity, and other properties. Hence a wide range of solder alloys exist, and only major ...
Rosin used as flux for soldering A flux pen used for electronics rework Multicore solder containing flux Wire freshly coated with solder, held above molten rosin flux. In metallurgy, a flux is a chemical reducing agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time.
The solder used in the process can vary in composition, with different alloys used for different applications. Common solder alloys include tin-lead, tin-silver, and tin-copper, among others. Lead-free solder has also become more widely used in recent years due to health and environmental concerns associated with the use of lead.
The lead-tin solder commonly used in electronics has 1 to 2% rosin by weight as a flux core, helping the molten metal flow and making a better connection by reducing the refractory solid oxide layer formed at the surface back to metal. It is frequently seen as a burnt or clear residue around new soldering.
Quoting the current text under heading Flux-core solder; "rosin flux used in electronics, where the corrosiveness of acid flux and vapours released when solder is heated would risk damaging delicate circuitry." Surely the danger is also to people exposed to fumes when hand soldering, or 'reworking' joints after wave/ reflow soldering. For which ...
An April 2017 article in The Daily Beast reported that Eastman Chemical's plant in Uruapan, Michoacán bought pine rosin (refined, solidified resin) from a supplier that was known to be controlled by the Knights Templar criminal cartel, even after being notified of the supplier's criminal links. The supplier (Unored) was using the cartel to ...
Although solder paste typically contains around 90% metal in solids by weight, the volume of the soldered joint is only about half that of the solder paste applied. [7] This is due to the presence of flux and other non-metallic agents in the paste, and the lower density of the metal particles when suspended in the paste as compared to the final ...
