Conformity

MEN products are no ready-made products for end users. They are tested according to

the standards given in the Technical Data and thus enable you to achieve certification of

the product according to the standards applicable in your field of application.

RoHS

Since July 1, 2006 all MEN standard products comply with RoHS legislation.

Since January 2005 the SMD and manual soldering processes at MEN have already been

completely lead-free. Between June 2004 and June 30, 2006 MEN’s selected component

suppliers have changed delivery to RoHS-compliant parts. During this period any change

and status was traceable through the MEN ERP system and the boards gradually became

RoHS-compliant.

WEEE Application

Nevertheless, MEN is registered as a manufacturer in Germany. The registration number

can be provided on request.

The WEEE directive does not apply to fixed industrial plants and tools. The

compliance is the responsibility of the company which puts the product

on the market, as defined in the directive; components and sub-

assemblies are not subject to product compliance.

In other words: Since MEN does not deliver ready-made products to end

users, the WEEE directive is not applicable for MEN. Users are

nevertheless recommended to properly recycle all electronic boards

which have passed their life cycle.

1.4 Cooling Concept

1.4.1 Cooling of Rugged COM Express Modules (VITA 59)

Rugged COM Express modules (VITA 59) are equipped with four cooling wings for

conduction cooling. These transport the heat generated on the board to a frame and

cover enclosing the module.

The frame and cover are only part of the thermal solution for a module. They provide a

common interface between the Rugged COM Express module and implementation-

specific thermal solutions.

The module can, e.g., be cooled via conduction cooling, where the heat is transported to

a housing or a heat sink built on top of the cover. It depends on the system configuration

and airflow if an additional heat sink is needed or not. In any case you should check your

thermal conditions and implement appropriate cooling.

Figure 4. RCE thermal concept – cooling wings between frame and cover

See Chapter 3.3 Trusted Platform Module (TPM) on page 23.

If you do not use the cover and frame supplied by MEN and/or no heat

sink, warranty on functionality and reliability of the CB71C may cease. If

you have any questions or problems regarding thermal behavior, contact

MEN.

1.4.2 Cooling of COM Express Modules (COM.0)

MEN’s modules are also available without the cooling wings, frame and cover as

standard COM Express modules in accordance with the PICMG COM.0 standard. They

are suitable for applications where operating temperatures are moderate and a suitable

low-power processor and airflow is used.

COM Express modules may also need additional cooling facilities, depending on the

configuration of the board and the general system design, i.e. integration of the

computer-on-module into the system. Implementation is up to the customer.

A general heat spreader solution, e.g., for evaluation purposes, is available from MEN as

an accessory for COM Express models.

See Chapter 3.3 Trusted Platform Module (TPM) on page 23.
