3. Solder paste - Wikipedia

   en.wikipedia.org/wiki/Solder_paste

   The size and shape of the metal particles in the solder paste determines how well the paste will "print". A solder ball is spherical in shape; this helps in reducing surface oxidation and ensures good joint formation with the adjoining particles. Irregular particle sizes are not used, as they tend to clog the stencil, causing printing defects.

   Care had to be taken not to melt the little granules onto the surface but instead, to solder them on with a tiny heated point. The various omissions and imperfections, made on purpose, gave the piece of jewelry the artistic character.

   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.
