This clause specifies the information requirements for the
Assembly module design
application module. The information requirements are specified as the
Application Reference Model (ARM) of this application module.
NOTE 1 A graphical representation of the information
requirements is given in
Annex C.
NOTE 2 The mapping specification is specified in

This subclause specifies the ARM type
for this application module. The ARM type and
definition is specified below.
The assembly_module_or_assembly_group_component type is an
extensible list of alternate data types
that allows for the designation of the data
type
Assembly_module_design_view.
NOTE
The list of entity data types may be
extended in application modules that use the constructs of
this module.

END_TYPE;
(*
This subclause specifies the ARM entities for this
module. Each ARM application entity is an atomic element that
embodies a unique application concept and contains attributes
specifying the data elements of the entity. The ARM
entities and definitions are specified below.
An Assembly_module_design_view is a type of
Assembly_definition
and a type of
Part_design_view.
An Assembly_module_design_view is a view of a product sufficiently detailed for a manufacturer to
assemble the materials that compose the product into a form suitable for customer delivery.
An Assembly_module_design_view is also a design view of a product, that is, a view created by a design organization
for manufacturing.
This application object supports design reuse, modular product definitions,
component libraries, and related technologies. There may be discipline views that further specialize this view.
NOTE 1
A design organization may create several product views during the development process. Not all
views are intended for manufacturing purposes.
EXAMPLE
Figure 1 is an illustration of an Assembly_module_design_view.
Figure 1 — Assembly module design view
NOTE 2
An Assembly_module_design_view could be a
ball grid array design, an MCM design, a disk drive design,
a line card or plug-in module in a telecommunications rack,
or a line replaceable unit in an airframe or spacecraft. Incomplete designs that
have some specified functionality as defined by a functional definition
may be included in a component library application, for example.
The designs may be included in an active design by reference. At the appropriate time in the
design phase, the single reference is replaced with individual references to the elements that compose the
Assembly_module_design_view. Support is provided for maintaining the information necessary to trace
back to the original Assembly_module_design_view from the released
Assembly_component
through the
Component_feature_to_physical_usage_view_assignment.
NOTE 3
Additional
Product
categories other than
Layered_assembly_module_design_view,
such as MCM-L (Multichip Module,
Laminated), MCM-D (Multichip Module, Deposited) and MCM-C (Multichip
Module, Ceramic) may be included through the use of this application object,
and population of the Class
application objects.
EXPRESS specification:
*)
ENTITY Assembly_module_design_view
SUBTYPE OF (Assembly_definition, Part_design_view);
WHERE
WR1: NOT EXISTS(SELF\Product_view_definition.additional_characterization);
END_ENTITY;
(*
Formal propositions:
WR1:
The
additional_characterization
shall not be populated.
A Component_external_reference is an unambiguous reference to a Next_assembly_usage in a different design.
EXAMPLE
Items in an Layered_interconnect_module_design_view may need to reference component to assembly relationships in the assembly in order to unambiguously identify the source of
layout requirements.
EXPRESS specification:
*)
ENTITY Component_external_reference;
design_owner : STRING;
part_number : STRING;
revision_code : STRING;
product_definition_id : STRING;
reference_designation : STRING;
END_ENTITY;
(*
Attribute definitions:
design_owner:
specifies text for the Component_external_reference. The design_owner is the organization that maintains the registration document for the part_number for the reference assembly. Usually it is the design authority.
part_number:
specifies text for the Component_external_reference. The part_number identifies the reference assembly in the context of the design_owner.
revision_code:
specifies text for the Component_external_reference. The revision_code identifies the version of the reference assembly.
NOTE
Usually the revision_code and part_number identify the original assembly for which an interconnect is designed.
product_definition_id:
specifies text for the Component_external_reference. The product_definition_id identifies the original Product_view_definition for the assembly. If not available in the originating system, the string "UNKNOWN" shall be provided.
reference_designation:
specifies text for the Component_external_reference. The reference_designation uniquely identifies the externally referenced component in the reference assembly.
A Component_feature_external_reference is an unambiguous reference to a
Component_feature
in a different design.
EXAMPLE
Items in an
Layered_interconnect_module_design_view
may need to reference component features in a reference assembly in order to unambiguously identify source of layout requirements.
EXPRESS specification:
*)
ENTITY Component_feature_external_reference;
name : STRING;
associated_component : Component_external_reference;
UNIQUE
UR1: associated_component, name;
END_ENTITY;
(*
Attribute definitions:
name:
specifies the words by which the Component_feature_external_reference is known.
associated_component:
specifies the role of the
Component_external_reference
for the Component_feature_external_reference.
Formal propositions:
UR1:
The combination of associated_component and name shall be unique within a population of Component_feature_external_reference.
A Component_mounting_clearance_relationship is the relationship
between the features of one component and another in their next assembly, with respect to the clearance between them.
NOTE 1
This clearance is required when a specific component requires a minimum distance from the printed circuit board or another
specific component.
NOTE 2
This clearance is often derived from the mechanism requirements of the factory equipment that assembles the components to
their next assembly.
The mechanical handling fingers that grasp and place a component require clearance from previously placed components in
order to place the second component and release it from the mechanism.
EXPRESS specification:
*)
ENTITY Component_mounting_clearance_relationship;
feature_relationship : Component_feature_relationship;
mounting_clearance : Length_tolerance_characteristic;
END_ENTITY;
(*
Attribute definitions:
feature_relationship:
specifies the role of the
Component_feature_relationship
for the Component_mounting_clearance_relationship.
mounting_clearance:
specifies the role of the
Length_tolerance_characteristic
for the Component_mounting_clearance_relationship.
The value shall be interpreted as the specification to be satisfied by the assembly process.
A Component_mounting_feature is a type of
Physical_component_feature intended for mounting purposes where the definition is a Part_mounting_feature.
EXPRESS specification:
*)
ENTITY Component_mounting_feature
SUBTYPE OF (Physical_component_feature);
SELF\Component_feature.definition : Part_mounting_feature;
END_ENTITY;
(*
Attribute definitions:
definition:
an attribute inherited from the
Component_feature
shall be redeclared as Part_mounting_feature
for the Component_mounting_feature.
A Minimally_defined_component_terminal is a type of
Physical_component_terminal
that is included to permit
references to terminals without including geometric representations of the terminals.
EXPRESS specification:
*)
ENTITY Minimally_defined_component_terminal
SUBTYPE OF (Physical_component_terminal);
SELF\Component_feature.definition : Part_terminal_external_reference;
WHERE
WR1: NOT EXISTS(SELF\Shape_element.description);
END_ENTITY;
(*
Attribute definitions:
definition:
specifies the role of the
Part_terminal_external_reference
for the Minimally_defined_component_terminal.
Formal propositions:
