2. Solder alloys - Wikipedia

   en.wikipedia.org/wiki/Solder_alloys

   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 ...

3. Flux (metallurgy) - Wikipedia

   en.wikipedia.org/wiki/Flux_(metallurgy)

   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.

4. Solder paste - Wikipedia

   en.wikipedia.org/wiki/Solder_paste

   The paste manufacturer will suggest a suitable reflow temperature profile to suit their individual paste. The main requirement is a gentle rise in temperature to prevent explosive expansion (which can cause "solder balling"), yet activate the flux. Thereafter, the solder melts. The time in this area is known as Time Above Liquidus. A reasonably ...

5. Solder - Wikipedia

   en.wikipedia.org/wiki/Solder

   Easy solder or repair solder are also often used for repair work for the same reason. Flux is also used to prevent joints from desoldering. Silver solder is also used in manufacturing to join metal parts that cannot be welded. The alloys used for these purposes contain a high proportion of silver (up to 40%), and may also contain cadmium.

6. Rosin - Wikipedia

   en.wikipedia.org/wiki/Rosin

   In industry, rosin is a flux used in soldering. 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 ...

7. Fume extractor (soldering) - Wikipedia

   en.wikipedia.org/wiki/Fume_extractor_(soldering)

   Fumes generated by soldering A woman at a bench working in front of a filtration system A fume extractor is a device used to filter aerosolized chemical byproducts of the soldering process. [ 1 ] These devices take many forms depending on the project size and application, from small ductwork to entire fume hoods. [ 2 ]
