1. Values in inches are converted from mm and rounded to 3 decimal digits.

Notes (to be reported in Note column of Table 70).

1. Dimensioning and tolerancing schemes conform to ASME Y14.5M-1994.

2. All dimensions are in millimeters unless otherwise stated. Values in inches are converted from mm and

rounded to 3 decimal digits.

3. Terminal A1 identifier and terminal numbering convention shall conform to JEP95 SPP-002.

Terminal A1 identifier must be located within the zone indicated on the outline drawing. Topside terminal A1

indicator may be a molded, or metalized feature. Optional indicator on bottom surface may be a molded,

marked or metallized feature.

4. Outlines with “D” and “E” increments less than 0.5 mm should be registered as “stand alone” outlines. These

outlines should use as many of the algorithms and dimensions states in the design standard as possible to

insure predictability in manufacturing.

5. Dimension ‘b’ applies to metallized terminal and is measured between 0.15 mm and 0.30 mm from the

terminal tip. If the terminal has the optional radius on the other end of the terminal, the dimension ‘b’ should

not be measured in that radius area.

6. Inner edge of corner terminals may be chamfered or rounded in order to achieve minimum gap “k”.

This feature should not affect the terminal width “b”, which is measured L/2 from the edge of the package

body.

7. Exact shape of the leads at the edge of the package is optional.

8. “N” is the maximum number of terminal positions for the specified body size. Depopulation is allowed, but only

under the following conditions.

–

Depopulation scheme must be consistent in each quadrant of the package.

–

Non-symmetric variations should be broken out as separate mechanical outline variations, including

depopulation graphics.

9. A1 is defined as the distance from the seating plane to the lowest point on the package body (standoff).

10. Dimension D2 and E2 refer to exposed pad. For exposed pad dimensions see Variations Table 70.
