E1
1. Metallized castellations shall be connected to plane 1 terminals
and extend toward plane 2 across at least two layers of ceramic
or completely across all of the ceramic layers to make electrical
connection with the optional plane 2 terminals.
L2
E2
B2
2. Unless otherwise specified, a minimum clearance of 0.015 inch
(0.38mm) shall be maintained between all metallized features
(e.g., lid, castellations, terminals, thermal pads, etc.)
L1
D2
3. Symbol “N” is the maximum number of terminals. Symbols “ND”
and “NE” are the number of terminals along the sides of length
“D” and “E”, respectively.

4. The required plane 1 terminals and optional plane 2 terminals (if
used) shall be electrically connected.
5. The corner shape (square, notch, radius, etc.) may vary at the
manufacturer’s option, from that shown on the drawing.
6. Chip carriers shall be constructed of a minimum of two ceramic
layers.
7. Dimension “A” controls the overall package thickness. The maxi-
mum “A” dimension is package height before being solder dipped.
8. Dimensioning and tolerancing per ANSI Y14.5M-1982.
9. Controlling dimension: INCH.
