NOTES:

1. Index area; a notch or a pin one identification mark shall be located adjacent to pin one and shall be located Within the shaded area shown. The manufacturer's identification shall not be used as a pin one identification mark.

2. The minimum limit for dimension b1 may be .023 (.58 mm) for leads number 1, 14, 15, and 28 only.

3. Dimension Q shall be measured from the seating plane to the base plane.

4. This dimension allows for off-center lid, meniscus and glass overrun.

5. The basic pin spacing is .100 (2.54 mm) between centerlines. Each pin centerline shall be located within

±.010 (.25 mm) of its exact longitudinal position relative to pins 1 and 28.

6. Applies to all four corners (leads number 1, 14, 15, and 28).

7. Lead center when α = 0o. E1 shall be measured at the centerline of the leads.

8. All leads - Increase maximum limit by .003 (.08 mm) measured at the center of the flat, when lead finish A or

B is applied.

9. Twenty six spaces.

10. If this configuration is used, no organic or polymeric materials shall be molded to the bottom of the package to cover the leads.
