Abstract
A surface mountable pin connector has a substrate or a circuit board carrier, which has a number of through holes or vias formed therein, and a number of connector pins, each of which is soldered into a respective one of the through holes with high melt temperature solder. A damming device or protrusion is located on each pin nearer to the shoulder than typical interference fit protrusions. The damming device is sized and shaped to completely block the through hole or via.
