This is the male pin half of a differential-pair backplane interconnect system, terminated via press-fit compliant pins that press into plated through-holes without solder. ## Press-Fit Termination for Backplane Assembly Press-fit termination means this header is designed for solderless assembly into a backplane PCB. The compliant pin eyelet compresses as it enters the plated through-hole, creating a gas-tight mechanical and electrical connection. This avoids the thermal stress of wave or reflow soldering on a large, multi-layer backplane board. The through-hole mounting type is standard for backplane connectors where the header is inserted from the top side and the compliant tail engages the inner-layer vias. ## 72 Circuits, 6 Columns — Footprint and Routing 72 positions loaded across 6 columns. All positions are loaded.","metaTitle":"TE Impact 2149979-3 Header, 72 Pos, Press-Fit","metaDescription":"TE Connectivity Impact 2149979-3 header, 72 positions, 6 columns, press-fit termination, 30.0µin gold.
