Thermal Considerations
CPU DIE TEMPERATURE
The CPU die temperature is affected by numerous conditions, such as CPU utilization, CPU
speed, ambient air temperature, air flow, thermal effects of adjacent circuit boards, external heat
sources, and many others.
The CPU is protected from over-temperature conditions by several mechanisms, including
Minimum Frequency Mode (MFM), coreclock modulation, and THERMTRIP#.
See the 3rd Generation Intel® Embedded Mobile Processor Datasheet, Vol. 1 for complete
information on CPU thermal considerations.
As a failsafe, if the CPU die temperature climbs above +105°C, the CPU will turn itself off to
prevent damage to the chip. Note that Intel does not warrant their CPUs in the event of this
occurrence.
MODEL DIFFERENCES
VersaLogic offers both commercial and industrial temperature models of the VL-EBX-41. The
basic operating temperature specification for Copperhead models is shown below.

(0.5 Linear Meters per Second)
For heat plate only models, the customer-provided thermal solution must keep the heat plate
below 90°C, measured top dead center of the heat plate. For example, for an 85°C ambient
temperature, the thermal solution needs to:
Dissipate 45W with a 5°C delta between ambient and the heat plate
Thermal resistance = 0.11°C / W for the 45W unit
See Figure 6 for heat plate dimensions and mounting holes.

EBX-41 Reference Manual 5
Warnings
ELECTROSTATIC DISCHARGE
Warning! Electrostatic discharge (ESD) can damage circuit boards, disk drives and other
components. The circuit board must only be handled at an ESD workstation. If an
approved station is not available, some measure of protection can be provided by
wearing a grounded antistatic wrist strap. Keep all plastic away from the board and
do not slide the board over any surface.
After removing the board from its protective wrapper, place the board on a
grounded, static-free surface, component side up. Use an antistatic foam pad if
available.
The board should also be protected inside a closed metallic anti-static envelope
during shipment or storage.
Note The exterior coating on some metallic antistatic bags is sufficiently conductive to
cause excessive battery drain if the bag comes in contact with the bottom-side of
the VL-EBX-41.
LITHIUM BATTERY
Warning! To prevent shorting, premature failure or damage to the lithium battery, do not
place the board on a conductive surface such as metal, black conductive foam or
the outside surface of a metalized ESD protective pouch. The lithium battery may
explode if mistreated. Do not recharge, disassemble or dispose of in fire. Dispose
of used batteries promptly and in an environmentally suitable manner.
HANDLING CARE
Warning! Care must be taken when handling the board not to touch the exposed circuitry
with your fingers. Though it will not damage the circuitry, it is possible that small
amounts of oil or perspiration on the skin could have enough conductivity to cause
the contents of BIOS RAM to become corrupted through careless handling,
resulting in BIOS resetting to factory defaults.
EARTH GROUND REQUIREMENT
Warning! All mounting holes (eight on EBX and EPIC boards, four on PC/104 boards)
should be connected to earth ground (chassis ground). This provides proper
grounding for ESD and EMI purposes. In portable applications, the mounting holes
should be connected to the ground reference of the system power supply.

HARDWARE ASSEMBLY
The VL-EBX-41 mounts on four hardware standoffs using the corner mounting holes (A). These
standoffs are secured to the underside of the circuit board using pan head screws.
Four additional standoffs (B) must be used under the circuit board to prevent excessive flexing
when expansion modules are mated and separated. These are secured with four male-female
standoffs (C), threaded from the top side, which also serve as mounting struts for the expansion
stack.
The entire assembly can sit on a table top or be secured to a base plate. When bolting the unit
down, make sure to secure all eight standoffs (A and B) to the mounting surface to prevent
circuit board flexing.
An extractor tool is available (part number VL-HDW-203) to separate expansion modules from
the stack.
Note Standoffs and screws are available as part number VL-HDW-105 (metric M3
thread) or VL-HDW-106 (English thread).
Note Where possible, all eight mounting standoffs should be connected to earth ground
(chassis ground). This provides proper grounding for ESD and EMI protection.
