Ceramic Metal Seal Flatpack Packages (Flatpack)

NOTES:

1. Index area: A notch or a pin one identification mark shall be locat-

ed 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. Alternately, a tab (dimension k)

may be used to identify pin one.

2. If a pin one identification mark is used in addition to a tab, the lim-

its of dimension k do not apply.

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

4. Dimensions b1 and c1 apply to lead base metal only. Dimension

M applies to lead plating and finish thickness. The maximum lim-

its of lead dimensions b and c or M shall be measured at the cen-

troid of the finished lead surfaces, when solder dip or tin plate

lead finish is applied.

5. N is the maximum number of terminal positions.

6. Measure dimension S1 at all four corners.

7. For bottom-brazed lead packages, no organic or polymeric mate-

rials shall be molded to the bottom of the package to cover the

leads.

8. Dimension Q shall be measured at the point of exit (beyond the

meniscus) of the lead from the body. Dimension Q minimum

shall be reduced by 0.0015 inch (0.038mm) maximum when sol-

der dip lead finish is applied.

9. Dimensioning and tolerancing per ANSI Y14.5M - 1982.

10. Controlling dimension: INCH.
