84-position Sliver 2.0 edge connector at 0.60 mm pitch
The TE Connectivity 2327678-2 is an 84-position female edge-card connector from the Sliver 2.0 series, built for high-density board-to-board interconnects where signal count per linear inch matters. The 0.60 mm pitch and dual-row readout — 28 positions per bay, 14 per row — pack 84 circuits into a compact footprint that mates with a standard 0.062 inch (1.57 mm) PCB edge card. Gold-plated contacts with 15.0 µin finish handle repeated mating cycles typical in server riser cards, mezzanine assemblies, and PCIe-style add-in boards. The black LCP housing carries board guide, pick-and-place, and solder retention features for automated SMT assembly.
What the 0.60 mm pitch and 84 positions mean for the board layout
At 0.60 mm pitch, the card-edge pads on the mating PCB must be tightly toleranced — this is not a forgiving footprint for hand-routed boards. The dual-row readout means the connector reads both sides of the edge card, so the PCB must have matching pad patterns on top and bottom layers. 84 positions at this pitch give roughly 25 mm of connector body length, which fits within the edge of a standard PCIe card form factor. The card thickness spec of 0.062 inch matches standard FR4 board build-up, so no special core stack-up is needed.
SMT assembly and solder retention features
These are standard for high-volume SMT lines — the connector is designed to run through a pick-and-place machine without hand placement. The LCP insulation material withstands lead-free reflow temperatures without warping.
Temperature range and operating environment
This range does not extend to under-hood automotive or outdoor cabinet duty where extended 105°C or 125°C ratings would be needed. The gold-over-copper-alloy contacts resist corrosion in non-sealed environments typical of card-edge applications.
