aaa

The bilateral profile tolerance that

controls the position of the plastic body

sides. The centers of the profile zones

are defined by the basic dimensions D

and E.

bbb

The tolerance that controls the position

of the entire terminal pattern with

respect to Datum’s A and B. The center

of the tolerance zone for each terminal

is defined by the basic dimension “e” as

related to Datum’s 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

centers of the profile zones are defined

by basic dimension “e”.

This tolerance is normally compounded

with tolerance zone defined by bbb.

eee

The unilateral tolerance located above

the seating plane where in the bottom

surface of all terminals must be located.

This tolerance is commonly known

as the “coplanarity” of the package

terminals.
