Board-to-Board Stacking with the MICTOR 1658015-2
The TE Connectivity 1658015-2 is an 80-position plug from the MICTOR series, designed for high-density board-to-board mezzanine stacking. The connector sits 0.404" (10.27mm) above the board and achieves an 11mm mated stack height with the matching receptacle — a common spacing for parallel card assemblies in telecom and computing backplanes. The integrated ground bus (plane) runs through the connector body to reduce loop inductance, a feature aimed at maintaining signal integrity on fast parallel buses where every nanohenry of return path inductance eats into the noise margin. The surface mount termination keeps the assembly compatible with reflow soldering, and the board guide features help align the plug during hand or automated placement.
