  2. Reflow soldering - Wikipedia

    en.wikipedia.org/wiki/Reflow_soldering

    Reflow soldering is a process in which a solder paste (a sticky mixture of powdered solder and flux) is used to temporarily attach anywhere from one to thousands of tiny electrical components to their contact pads, after which the entire assembly is subjected to controlled heat. The solder paste reflows in a molten state, creating permanent ...

  3. Rework (electronics) - Wikipedia

    en.wikipedia.org/wiki/Rework_(electronics)

    Reballing involves dismantling, heating the chip until it can be removed from the board, typically with a hot-air gun and vacuum pickup tool, removing the device, removing solder remaining on the device and board, putting new solder balls in place, replacing the original device if there was a poor connection, or using a new one, and heating the ...

  4. Soldering station - Wikipedia

    en.wikipedia.org/wiki/Soldering_station

    Stations with hot air guns are used in cases when just a soldering iron is not enough. Disassembling microchips requires a hot air gun. SMD components soldering with hot air is much more convenient. Hot air guns usually come with special nozzles for hot air stream regulation. Popular manufacturers: Hakko, Quick, Accta, Goot, etc.

  5. Selective soldering - Wikipedia

    en.wikipedia.org/wiki/Selective_soldering

    Sensors installed to a fixture to check selective solder machine parameters 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.

  6. Soldering - Wikipedia

    en.wikipedia.org/wiki/Soldering

    Reflow soldering is a process in which a solder paste (a mixture of prealloyed solder powder and a flux-vehicle that has a peanut butter-like consistency [8]) is used to stick the components to their attachment pads, after which the assembly is heated by an infrared lamp, a hot air pencil, or, more commonly, by passing it through a carefully ...

    The U.S. Preventive Services Task Force released a draft recommendation advising against using vitamin D to prevent falls and fractures in people over 60. Pharmacist Katy Dubinsky weighs in.

  8. 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 ...
