2. Wave soldering - Wikipedia

   en.wikipedia.org/wiki/Wave_soldering

   Wave soldering is a bulk soldering process used in printed circuit board manufacturing. The circuit board is passed over a pan of molten solder in which a pump produces an upwelling of solder that looks like a standing wave. As the circuit board makes contact with this wave, the components become soldered to the board.

3. Solder paste - Wikipedia

   en.wikipedia.org/wiki/Solder_paste

   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 ...

   Proper cleaning removes all traces of solder flux, as well as dirt and other contaminants that may be invisible to the naked eye. No-Clean or other soldering processes may leave "white residues" that, according to IPC, are acceptable "provided that these residues have been qualified and documented as benign". [10]

5. Stencil printing - Wikipedia

   en.wikipedia.org/wiki/Stencil_Printing

   Ideally, a solder paste should have, at minimum, a 4-hour stencil life. The stencil life is defined as a time period in which there will be no significant change in the solder paste material characteristics. A solder paste with a longer stencil life will be more robust in the printing process.

7. Soldering - Wikipedia

   No-clean fluxes – mild enough to not "require" removal due to their non-conductive and non-corrosive residues. [8] These fluxes are called "no-clean" because the residue left after the solder operation is non-conductive and will not cause electrical shorts; nevertheless they leave a plainly visible white residue.
