. De-soldering The removal of solder and components from a circuit, usually for purposes of repair. De-wetting A condition where molten solder has coated a surface and then receded, leaving irregularly shaped mounds of solder separated by areas covered with a thin solder film

theory correlating the effects of surface geometry on the rate of atomic diffusion, as well as proximity to the solder flow. The main reason for the variance across a connector has been linked to flow rate. Typical flow-well design utilizes a single

. Simpler and faster automated assembly. Some placement machines are capable of placing more than 136,000 components per hour. Small errors in component placement are corrected automatically as the surface tension of molten solder pulls components into alignment with solder pads

. This stage is the most important. When the individual solder particles are completely melted, they combine to form liquid tin. At this time, the surface tension starts to form the surface of the solder foot, and the molecular motion is violent, so that the liquid tin and copper form a good alloy
