PACKAGE DIM ENSIONS
NOTES:
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 m aximum of .040 inch (1.020
mm).
4. The corner shape (square, notch, radius, etc.) may vary at the
manufacturer's option, from that shown on the drawing.
5. Di mensions " LW2" mini mu m and "L3" minimu m and the
appropriate castellation length define an unobstructed three-
dimensional space traversing all of the ceramic l ayers in which a
castellation was designed. (Castellations are required on bottom
two l ayers, optional on top ceramic layer.) Dimension " LW2"
maximum and "L3" maximum define the maximum width and
depth of the c astellation at any point on its surface.
Measurement of these dimensions may be made prior to solder
dipping.
6. The co-planarity deviation of all term inal contact points, as
defined by the device seating plane, shall not exceed .006 inch
(0.15mm) for solder dipped leadless chip carriers.
7. I n accordance wit h ASME Y14.5M, diameters are equivalent to
Φx symbology.
