5.1 Shape of package outlines for components

The classification scheme for the shapes of package outlines is based on the following three

characteristics of the package according to the codes defined in IEC 60191-4:

– outline style ;
– terminal position;
– terminal form.
Based on these characteristics, five levels of classification are defined as follows:

– level 1: outline style;
– level 2: terminal position;
– level 3: terminal form;
– level 4: terminal variant;
– level 5: body variant (optional).
The specification of each class at the lowest level of the classification tree of the component
package shapes contains an attribute which makes a reference to a unique drawing. This
associated drawing contains the graphical representation of the data element types describing
the characteristic dimension parameters of that specific component package geometry.
Each drawing is unambiguously identified by an identifier. Also associated with each drawing
is a descriptive designator which is derived from the coded name of the relevant class in the
component package classification tree (see 6.1.5).
