Backplane Header for High-Speed Differential Routing
The TE Connectivity 6469025-1 is a 60-position header from the Z-PACK HM-Zd series, designed as a high-speed backplane connector. It uses a 4-row by 10-column grid at a 0.098" (2.50mm) pitch, with a contact layout of 40 signal and 20 ground contacts — the ground pins provide return-path density for differential pairs. The press-fit termination eliminates solder joints, which keeps the assembly compatible with reflow-free backplane builds and reduces thermal stress on the board.
Press-Fit Termination and Backplane Fit
The through-hole mounting provides mechanical retention against the insertion force of the mating receptacle. The 60-position count matches a 10-column backplane pattern. The 4-row arrangement with dedicated ground contacts keeps the signal-to-ground ratio balanced for controlled impedance routing.
