2.5 Mechanical Design
The SB-3642 is a Front-I/O air-cooled PCI Mezzanine Card (PMC) designed to meet
or exceed vibration requirements specified in VITA-47 for a class V2 in air-cooled
applications. The SB-3642
card also features CCPMC (Conduction Cooled PMC)
thermal rails and connector “anti-fretting” mounting holes per VITA-20-2005.
The front panel I/O connector layout uses a 68-pin front panel connection. The board
has conduction rails that do not interfere with the front panel connector. The front
panel connector includes a metal backshell with fastening thumbscrews.
The SB-3642 is designed to meet or exceed the humidity requirements of ANSI/VITA
47, and has been tested to withstand 95% humidity.
To operate within the specified -40 to +85
°
C operating temperature, supplemental air
cooling of 300 LFM (Linear Feet per Minute) in the system is required. The SB-3642
utilizes a custom heat sink design using the conduction cooled rails to efficiently
operate within the temperature range.
MTBF (Mean Time Between Failure) report is available upon factory request.
