2. Copper tubing - Wikipedia

   en.wikipedia.org/wiki/Copper_tubing

   While pipe sizes in Australia are inch-based, they are classified by outside rather than inside diameter (e.g., a nominal 3 ⁄ 4 inch copper pipe in Australia has measured diameters of 0.750 inches outside and 0.638 inches inside, whereas a nominal 3 ⁄ 4 inch copper pipe in the U.S. and Canada has measured diameters of 0.875 inch outside and ...

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. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   The welding of metals differs from soldering and brazing in that the joint is made without adding a lower-melting-point material (e.g. solder); instead, the pipe or tubing material is partially melted, and the fitting and piping are directly fused. This generally requires piping and fitting to be the same (or compatible) material.

5. Solder alloys - Wikipedia

   en.wikipedia.org/wiki/Solder_alloys

   About 100 times slower erosion of copper than ordinary tin/lead alloys. Suitable for soldering thin copper platings and very thin copper wires. [56] Sn 60 Pb 39 Cu 1: Pb: No: Sn 60 Pb 38 Cu 2: 183: 190 [16] [17] Pb: Cu2. Copper content increases hardness of the alloy and inhibits dissolution of soldering iron tips and part leads in molten ...

6. Solder ring fitting - Wikipedia

   en.wikipedia.org/wiki/Solder_ring_fitting

   To obtain functional joints, the inside of the fitting and the outside of the copper pipe are cleaned using steel wool or cleaning tape, flux paste is applied, the pipe is inserted into the fitting and heat is applied from a portable butane torch or propane torch until a ring of solder shows at the edges of the fitting.

7. The Home Depot Pro - Wikipedia

   en.wikipedia.org/wiki/The_Home_Depot_Pro

   The Home Depot Pro Specialty Trades first began as Barnett in 1958 as Barnett Tube Fitting and Valve Company by the Leonard Barnett family. The initial purpose of Barnett was to supply copper tubing to customers through its catalog.

8. Heat-shrink tubing - Wikipedia

   en.wikipedia.org/wiki/Heat-shrink_tubing

   Specialty heat-shrink tubing, known as "solder sleeves", have a tube of solder inside of the heat-shrink tubing, allowing the heat source to electrically join the two wires by melting the solder and simultaneously insulate the junction with the tubing. Solder sleeves also commonly contain a ring of heat-activated sealant on the inside of each ...

9. Power electronic substrate - Wikipedia

   en.wikipedia.org/wiki/Power_electronic_substrate

   The substrate is attached to a heat spreader by soldering the bottom copper layer to it. A related technique uses a seed layer, photoimaging, and then additional copper plating to allow for fine lines (as small as 50 micrometres) and through-vias to connect front and back sides. This can be combined with polymer-based circuits to create high ...
