Notes:
1. Dimensioning and tolerancing conform to ASME Y14.5M-1994.
2. All dimensions are in millimeters,
θ
is in degrees.
3. N is the number of the terminal positions (N=24 or 28)
4. The terminal #1 identifier and terminal numbering convention shall conform to JEDEC publication
95 SPP-002, details of terminal #1 identifier are optional, but must be located within the zone
indicated. The terminal #1 identifier may be either A mold or marked feature.
5. Dimension b applies to metallized terminal and is measured between 0.15mm and 0.30mm 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. Depopulation is possible in a symmetrical fashion.
7. All variations may be constructed per figure 1. Variation may alternately be constructed per figure 2
if A2, D1 & E1 are specified in the dimension tables, in all cases, the minimum “K” value of 0.20mm
applies.
8. For a complete set of dimensions for each variation, see the individual variation and the common
dimensions and tolerance in table.
9. Depending on the method of lead termination at the edge of the package, pull back (L1) maybe
present, L minus L1 to be equal to or greater than 0.3mm.
10. When more than one variation (option) exists for the same profile height, body size (D x E), and
pitch, then those variations will be denoted by an additional dash number (ie, -1, -2, etc.) designator
to identify then, the new variations would be created from all or any of the following reasons lead
counts ,terminal lengths, and or thermal pad sizes.
11. Refer to JEDEC MO-220, Variation WGGD-8 (for 24PIN, QFN).
Refer to JEDEC MO-220, Variation WHHD-1 (for 28PIN, QFN).
