VITA 42 XMC Standard Products and Support

VITA 42 XMC is a widely deployed mezzanine Standard used in high-reliability computers implementing switched-fabric architectures. XMC combines PCI Mezzanine Card (PMC) with serial fabric technology on proven mezzanine form-factors.

In 2017, VITA updated XMC’s base specification to recommend solderball connectors. Original parts employed Paste-On-Pad attachment, while recommended parts utilize modern solderball technology. Listed below are the recommended SamArray connectors, plus optional JSOM ejector standoffs to assist in XMC card un-mating.

VITA 42 - SamArray

VITA 42 XMC specifies solderball-equipped SamArray connectors in 10mm and 12mm stack heights. Solder options include Lead-free and Tin-lead alloys.

*These are 2 mm taller than the Standard mezzanine connectors. While these have been used to achieve 12 mm stack heights, the VITA 42 XMC Standard recommends using ASP-103614-01 and ASP-103614-04.

VITA 42/V61 - JSOM

Some XMC mezzanine cards may present a challenge to unmate from their host. To aid in separation, Samtec has developed the JSOM (Micro Jack Screw Standoff.) They act as a traditional standoff when collapsed. An Allen-key unscrews and expands the jack screw, dividing the PCBs in a steady, even motion until the mezzanine is safely separated from its host. The JSOM standoff family includes M2.5, M3, and #4-40 hardware available in 10mm and 12mm stack heights.
