160-Position Mezzanine Receptacle at 0.60 mm Pitch
The TE Connectivity 1-5316560-1 is a 160-position receptacle from the Free Height (FH) GIGA series, designed for high-density board-to-board mezzanine connections. It uses center strip contacts in a dual-row layout on a tight 0.024" (0.60mm) pitch, with a specified mated stacking height of 4mm.
Board Layout Fit: Pitch, Stack Height, and Retention
At 0.60 mm pitch, this connector demands a fine-line PCB footprint — the routing channels between pads on a 160-position dual-row layout are narrow, so the board stack-up and trace width need to be planned for signal escape. The 4 mm mated stack height is the z-height the connector pair occupies once mated; it sets the board-to-board clearance in the mezzanine assembly.
