   Hence, tack life is the critical property of solder pastes. It is defined as the length of time that solder paste can remain exposed to the atmosphere without a significant change in tack properties. A solder paste with long tack life is more likely to provide the user with a consistent and robust printing process. Response-to-pause

3. Wave soldering - Wikipedia

   en.wikipedia.org/wiki/Wave_soldering

   Wave soldering is a bulk soldering process used for the manufacturing of printed circuit boards. 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.

4. Power electronic substrate - Wikipedia

   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 ...

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.

   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.
