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.

4.3.1 Interconnect_module_cavity_surface   

An Interconnect_module_cavity_surface is a type of Interconnect_module_surface_feature.

The Interconnect_module_cavity_surface forms an internal physical boundary of the interconnect substrate. The Interconnect_module_cavity_surface is represented by a closed curve in two dimensional representations and by a manifold surface in three dimensional representations.

NOTE 1   Care should be taken in pre-processors to ensure that both two and three dimensional representations adhere to reasonable industrial practice regarding tangential intersections of curves and straight line segments.

NOTE 2   The Interconnect_module_cavity_surface is represented as a simple or complex Cutout in the design view.

The Interconnect_module_edge_surface forms an outer physical boundary of the interconnect substrate. The Interconnect_module_edge_surface is represented by a closed curve in two dimensional representations and by a manifold surface in three dimensional representations.

EXAMPLE    The tinned surface of a Land is designed to accept a surface mount lead. The tinned surface of the Land would be bound to the Interconnect_module_interface_terminal by a feature to usage view assignment relationship.

NOTE    The distinction of an interface terminal for a substrate only exists to support classification of an application of a substrate as being a product application where the substrate is delivered as a discrete product versus the application where the design of the substrate is consumed in another substrate design and is not separately supplied as a product.

4.3.7 Interconnect_module_primary_surface   

An Interconnect_module_primary_surface is a type of Interconnect_module_surface_feature. An Interconnect_module_primary_surface identifies the primary surface of the Layered_interconnect_module_design_view for fabrication and assembly purposes. A member of Stratum_concept_to_physical_usage_view_assignment shall be populated in order to associate this object to the primary Stratum if a design view of the substrate is included in the data. An Interconnect_module_primary_surface is an approximation of the real primary surface.

NOTE    It is not usually the case that the physical material visible on the surface of the substrate or pcb is the same material as that of the primary Stratum. The level of information provided by this object is usually sufficient for assembly purposes, but will be in error by the thickness of the Stratum above the primary Stratum. That Stratum will be the material of at least part of the surface of the substrate. Full three-dimensional representation capability and location of individual Interconnect_module_component_terminal associated by Assembly_joint to the component feature being assembled to the substrate is required to represent exactly the mating conditions.

4.3.8 Interconnect_module_secondary_surface   

An Interconnect_module_secondary_surface is a type of Interconnect_module_surface_feature. An Interconnect_module_secondary_surface identifies the secondary surface of the Layered_interconnect_module_design_view for fabrication and assembly purposes. If a design view is populated, and correlation to a Stratum is provided, the Stratum associated with this member of Interconnect_module_primary_surface shall be the last Stratum in the design.

NOTE    The Stratum_concept_to_physical_usage_view_assignment, and Stratum_surface provide supporting data needed to resolve the position of the Stratum in the design. Because the secondary surface is derived structurally from the primary Stratum, there is no approximation made in the description.
