2. 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 ...

3. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   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.

4. Wave soldering - Wikipedia

   en.wikipedia.org/wiki/Wave_soldering

   Wave soldering is used for both through-hole printed circuit assemblies, and surface mount. In the latter case, the components are glued onto the surface of a printed circuit board (PCB) by placement equipment, before being run through the molten solder wave. Wave soldering is mainly used in soldering of through hole components.

5. Surface-mount technology - Wikipedia

   en.wikipedia.org/wiki/Surface-mount_technology

   If the circuit board is double-sided then this printing, placement, reflow process may be repeated using either solder paste or glue to hold the components in place. If a wave soldering process is used, then the parts must be glued to the board before processing to prevent them from floating off when the solder paste holding them in place is ...

6. 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.

   Consumer Reports states that PriceGrabber places the ads and pays a percentage of referral fees to CR, [25] who has no direct relationship with the retailers. [26] Consumer Reports publishes reviews of its business partner and recommends it in at least one case. [27]

9. 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 ...
