Component Side Definition
To clearly, univocally define what is e.g. the component’s NORTH side, EAST side
etc., following applies:
TABLE 6-21
For other cases, use following determination flow diagram (FIGURE 6-19).
Components with
leads at one side
lead side is SOUTH
Components with
leads at both the
opposite sides;
number of leads > 1
lead sides are NORTH and SOUTH; if a marker is present, it’s explic-
itely indicating the SOUTH side

Component Length and Width
Once you have determined the component’s sides definition (see section before),
you have to know what component sides are defined as length respectively width.
See following table for determination.
TABLE 6-22
REMARK: Please note that according to this definition NOT the longest component
side automatically is defined as “ length” !
Component Body and Outline
Depending on the component type, measurements are done component package
body-based or component package outline-based. See FIGURE 6-20.
