  2. 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.

  3. Soldering - Wikipedia

    en.wikipedia.org/wiki/Soldering

    A silversmith hard soldering of silver rings using flux and silver solder wire. "Hard soldering" or "silver soldering" is used to join precious and semi-precious metals such as gold, silver, brass, and copper. The solder is usually described as easy, medium, or hard in reference to its melting temperature, not the strength of the joint.

  4. Automotive battery - Wikipedia

    en.wikipedia.org/wiki/Automotive_battery

    An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle. Its main purpose is to provide an electric current to the electric-powered starting motor , which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.

  5. List of battery sizes - Wikipedia

    en.wikipedia.org/wiki/List_of_battery_sizes

    The full battery designation identifies not only the size, shape and terminal layout of the battery but also the chemistry (and therefore the voltage per cell) and the number of cells in the battery. For example, a CR123 battery is always LiMnO 2 ('Lithium') chemistry, in addition to its unique size.

  6. Solder - Wikipedia

    en.wikipedia.org/wiki/Solder

    The remaining solder types are used in decreasing order of hardness during the process of making an item, to prevent a previously soldered seam or joint desoldering while additional sites are soldered. 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.

  7. Flux (biology) - Wikipedia

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

    Flux is the net movement of particles across a specified area in a specified period of time. [1] The particles may be ions or molecules, or they may be larger, like insects, muskrats or cars. The units of time can be anything from milliseconds to millennia. Flux is not the same as velocity or speed nor is it the same as density or concentration.

  8. Flux - Wikipedia

    en.wikipedia.org/wiki/Flux

    Given a flux according to the electromagnetism definition, the corresponding flux density, if that term is used, refers to its derivative along the surface that was integrated. By the Fundamental theorem of calculus , the corresponding flux density is a flux according to the transport definition.

  9. Failure of electronic components - Wikipedia

    en.wikipedia.org/wiki/Failure_of_electronic...

    Residues of solder flux may facilitate corrosion; those of other materials on PCBs can cause electrical leaks. Polar covalent compounds can attract moisture like antistatic agents , forming a thin layer of conductive moisture between the traces; ionic compounds like chlorides tend to facilitate corrosion.
