One of the primary benefits of surface mount interconnects is the board real estate savings that can result from reducing the centerline spacing of the leads. While surface mount strips and DIPs on .100" (2,54mm) pitch might require slightly more space than their through-hole counterparts, 2mm by 2mm (.079" by .079") and .050" by .050" (1,27mm by 1,27mm) patterns have become quite common and offer significant space savings. As surface mount manufacturing processes become more precise, 1mm pitch is clearly on the horizon as the next generation of micro-surface mount interconnects.
