The TE Conectivity Z-PACK HS3 board to board backplane connector system has been designed for high speed serial data transfer. The controlled impedance microstrip path incorporated into the design of the Z-PACK HS3 minimises crosstalk and signal degradation. The HS3 is compatible with other Z-PACK family connectors as well as the Universal Power Module (UPM). The HS3 supports data rates of 6.2+ Gbits/s per differential pair.

The Z-PACK 2 mm HM Interconnection System is designed as a two part system for the connection of free boards (Daughterboards or PCBs) to fixed boards (Motherboards, Backplane or Backpanel) and feed the connection through the fixed board.
