ESD Precautions

Computer boards have integrated circuits sensitive to static electricity.
To prevent chipsets from electrostatic discharge damage, please take
care of the following jobs with precautions:

 Do not remove boards or integrated circuits from their anti-static

packaging until you are ready to install them.

 Before holding the board or integrated circuit, touch an unpainted

portion of the system unit chassis for a few seconds. It
discharges static electricity from your body.

 Wear a wrist-grounding strap, available from most electronic

component stores, when handling boards and components.

Introduction

The ETM831 Series is a finest embedded ETX system-on-a-module
in the market, which makes a generic interface to connect the module
to peripherals such as hard disk, mouse, and display. It supports

Intel

®

Atom N270 processor with 533MHz FSB (Front Side Bus).

The board integrates Intel

®

945GSE and ICH7M chipsets that support
one 200-pin DDR2-400/533 SDRAM with maximum up to 2GB system
memory capacity. It makes the all-in-one single module together with
excellent Multiple I/O, dual independent display CRT and LVDS LCD
through ETX connector, Fast Ethernet and 5.1 Channel HD Codec
Audio. Through ETX connectors, it also provide one FDD/LPT port,
four PCI and one full ISA bus for expansion purpose, one PATA, two
SATA and four USB 2.0 ports for high speed peripherals. It can
achieve the best stability and reliability that makes your system
perform the most endurable operation in any critical environments.
The built-in Watchdog Timer has enhanced the system reliability that
achieves a unique feature to distinguish itself from other boards.

2.3 Heatspreader Installation

1. There is a protective plastic covering on the thermal pads. This
must be removed before the heatspreader can be mounted.
Each heatspreader is designed for a specific ETM module. The
thermal pads on the heatspreader are designed to make contact
with the necessary components on the ETM module. When
mounting the heatspreader you must make sure that the thermal
pads on the heatspreader make complete contact (no space
between thermal pad and component) with the corresponding
components on the ETM module. This is especially critical for
ETM modules that have higher CPU speeds (for example

1.0GHz or more) to ensure that the heatspreader acts as a
proper thermal interface for cooling solutions.

2. The two M2.5x8 screws and two M2.5x12 screws are used to

mount the heatspreader and ETM module assembly to the
baseboard. (see Figure 1)

3. If you have an additional thermal solution on the heatspreader,

please refer to the ETM831 thermal solu tion design guide (see
Figure 2) to design your thermal solution.
