PACKAGE DIMENSIONS
NOTE:
1. Dimension are in inches.
2. Millimeters are given for general information only.
3. Beyond r (radius) maximum, TW shall be held for a minimum length of .011 inch (0.28 mm).
4. Dimension TL measured from maximum HD.
5. Body contour optional within zone defined by HD, CD, and Q.

NOTE:
1. Dimensions are in inches.
2. Millimeters are given for general information only.
3. Dimension CH controls the overall package thickness.
When a window lid is used, dimension CH must increase
by a minimum of .010 inch (0.254 mm) and a maximum
of .040 inch (1.020 mm).
4. The corner shape (square, notch, radius) may vary at the
manufacturer's option, from that shown on the drawing.
5. Dimensions LW2 minimum and L3 minimum and the
appropriate castellation length define an unobstructed
three-dimensional space traversing all of the ceramic
layers in which a castellation was designed.
(Castellations are required on the bottom two layers,
optional on the top ceramic layer.) Dimension LW2
maximum and L3 maximum define the maximum width
and depth of the castellation at any point on its surface.
Measurement of these dimensions may be made prior to
solder dipping.
6. The co-planarity deviation of all terminal contact points,
as defined by the device seating plane, shall not exceed
.006 inch (0.15mm) for solder dipped leadless chip
carriers.
7. In accordance with ASME Y14.5M, diameters are
equivalent to φx symbology.
