IMPORTANT SAFE-HANDLING INFORMATION
WARNING: ESD-Sensitive Electronic Equipment!
Observe ESD-safe handling procedures when working with this product.
Always use this product in a properly grounded work area and wear
appropriate ESD-preventive clothing and/or accessories.
Always store this product in ESD-protective packaging when not in use.
Safe Handling Precautions
Altair contains numerous I/O connectors that connect to sensitive electronic components. This creates many
opportunities for accidental damage during handling, installation and connection to other equipment. The list here
describes common causes of failure found on boards returned to Diamond Systems for repair. This information is
provided as a source of advice to help you prevent damaging your Diamond (or any vendor’s) embedded
computer boards.
ESD damage –This type of damage is almost impossible to detect, because there is no visual sign of failure or
damage. The symptom is that the board simply stops working, because some component becomes defective.
Usually the failure can be identified and the chip can be replaced.
To prevent ESD damage, always follow proper ESD-prevention practices when handling computer boards.
Damage during handling or storage –On some boards we have noticed physical damage from mishandling. A
common observation is that a screwdriver slipped while installing the board, causing a gouge in the PCB surface
and cutting signal traces or damaging components.
Another common observation is damaged board corners, indicating the board was dropped. This may or may not
cause damage to the circuitry, depending on what is near the corner. Most of our boards are designed with at
least 25 mils clearance between the board edge and any component pad, and ground / power planes are at least
20 mils from the edge to avoid possible shorting from this type of damage. However these design rules are not
sufficient to prevent damage in all situations.
A third cause of failure is when a metal screwdriver tip slips, or a screw drops onto the board while it is powered
on, causing a short between a power pin and a signal pin on a component. This can cause overvoltage / power
supply problems described below. To avoid this type of failure, only perform assembly operations when the
system is powered off.
Sometimes boards are stored in racks with slots that grip the edge of the board. This is a common practice for
board manufacturers. However our boards are generally very dense, and if the board has components very close
to the board edge, they can be damaged or even knocked off the board when the board tilts back in the rack.
Diamond recommends that all our boards be stored only in individual ESD-safe packaging. If multiple boards are
stored together, they should be contained in bins with dividers between boards. Do not pile boards on top of each
other or cram too many boards into a small location. This can cause damage to connector pins or fragile
components.
Power supply wired backwards –Our power supplies and boards are not designed to withstand a reverse
power supply connection. This will destroy each IC that is connected to the power supply. In this case the board
will most likely will be unrepairable and must be replaced. A chip destroyed by reverse power or by excessive
power will often have a visible hole on the top or show some deformation on the top surface due to vaporization
inside the package. Check twice before applying power!
Bent connector pins –This type of problem is often only a cosmetic issue and is easily fixed by bending the pins
back to their proper shape one at a time with needle-nose pliers. This situation can occur when pulling a ribbon
cable off of a pin header. Note: If the pins are bent too severely, bending them back can cause them to weaken
unacceptably or even break, and the connector must be replaced.

1.2 Thermal Considerations
All models of Altair are specified for a -40oC to +85oC operating range, the temperature being measured at the
outside surface of the heatspreader. Diamond Systems provides a heatspreader attached to the Altair single
board computer as a conductive cooled thermal layer. However, this heatspreader by itself does not constitute
the complete thermal solution necessary for any specific implementation, but provides a common interface
between the single board computer and the customer’s implementation-specific thermal solution.
The outside surface of the Altair heatspreader must be kept at a temperature not to exceed +85oC. If your
environment causes the temperature on the outside surface of the heatspreader to exceed this temperature, you
are responsible for removing the additional heat from the system through either an additional passive thermal
solution or fan solution.
