Reflow-related causes: • Improper pad design may be aggravated by use of nitrogen. The nitrogen increases surface tension of the metals to the extent that a previously marginal problem becomes distinct

. As the temperature increases further, the surface tension of the solder decreases. The solder climbs to a certain height of the component pins. 4

. 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
