Table 91. Tolerance of form and position symbol definition

Symbol

Definition

aaa

The bilateral profile tolerance that controls the position of the plastic body sides. The centres of the profile zones are

defined by the basic dimensions D and E.

bbb

The tolerance that controls the position of the terminals with respect to Datums A and B. The centre of the tolerance

zone for each terminal is defined by basic dimension e as related to datums A and B.

ccc

The tolerance located parallel to the seating plane in which the top surface of the package must be located.

ddd

The tolerance that controls the position of the terminals to each other. The centres of the profile zones are defined

by basic dimension e.

eee

The unilateral tolerance located above the seating plane wherein the bottom surface of all terminals must be located

= coplanarity

fff

The tolerance that controls the position of the exposed metal heat feature. The centre of the tolerance zone is the

data defined by the centrelines of the package body
