VITA 42 XMC Wide Module Connectors

A connector set compliant with the revised ANSI/VITA 42.0-2016 XMC Standard, the VITA 42 XMC defines an open standard for supporting high-speed, switched interconnect protocols on an existing, widely deployed form factor.

This revision further defined the concept for the preferred Standard connectors in XMC applications including:

• Solder ball attachment replaced Paste-On-Pad (POP) for improved solder joints
• Low Insertion Force (LIF) sockets to ease mating and un-mating
• Tin-lead alloy available as a solder option
• Revised ASP catalog numbers
• 12 mm stack height

Based on these guidelines, the 12 mm stack height options expand the existing family of ANSI/VITA 42 XMC Standard connectors. Chosen for high reliability stemming from the multipoint-of-contact SamArray sockets and robust solder ball design, the updated connector set has been specified for current XMC systems.

In addition to transmitting sensitive high-speed data, these connectors provide power, ground, and auxiliary signals to the mezzanine. The 12 mm mated connector set further optimizes XMC cards for use in wider modules, designed for 1-in. pitch cage systems.
