EKF C20-SATA, Техническая информация

Страница: 9 / 28

Technical Information C20-SATA • SATA Dual-Drive Mezzanine Module
Mounting Alternates
The C20-SATA will be mounted with a headroom of either 6mm - 10mm - 14mm or 18mm above the
carrier board, depending on the number of drives engaged (one or two), the drive height (7.0mm
typically for solid state drives, 9.5mm assumed for hard disk drives), and components on the carrier
board e.g. PCIe Mini Card sockets.
The 6mm headroom assembly fits into the 4HP envelope of the carrier board, which results in a total
assembly height of 8HP including the CPU base board. This version is limited to a single drive.
The 10mm headroom version is suitable for a second drive, bottom mount (SSD 7mm). No
components >2.8mm height would be allowed on the carrier board below the C20-SATA. This
assembly exceeds the 4HP envelope of the carrier board slightly, if also on top is a SSD populated.
The 14mm headroom assembly exceeds the 4HP envelope definitely. With a bottom mount 9.5mm
hard drive, components on the carrier board situated below the C20-SATA must not be higher than
4.3mm (6.8mm with a 7.0mm SSD).
The nominal 18mm headroom version is suitable for a dual drive C20-SATA, while not imposing too
much restrictions on components on the carrier board. With the real 18.6mm stand-off bolts in use,
components on the carrier board may be as high as 8.9mm (9.5mm bottom mount HDD), or 11.4mm
(7.0mm bottom mount SSD). A common front panel of 12HP is recommended for the entire assembly
comprised of CPU base board, carrier side card, and the C20-SATA dual drive module. EKF offers also
custom specific front panel design.
The different assembly versions are achieved by choosing mezzanine connectors with a suitable
height, on both the C20-SATA and on the carrier board as well. Be sure to specify your individual
needs when ordering.
