SMJ320C40 (Rev. 5) Inner Lead Bond (ILB) Information for TAB
XXXXX
Figure 4. SMJ320C40 Die Numbering Format
(See Table 2)
The inner lead bond (ILB) pitch for the tape automated bonding (TAB) leadframe is the same as the die bond
pad pitch. Table 2 provides a reference for the following:
A.
The TAB lead numbers. The TAB lead numbers are the same as the die bond pad numbers.
B.
The C40 signal identities in relation to the pad numbers
C.
There are 325 bond pad locations, 325 TAB leads, and 324 test pad locations.
D.
The C40 X-,Y-coordinates, where bond pad 82 serves as the origin, (0,0)
E.
The inner lead bond pitch (ILB) is the same as the die bond pitch.
F.
The outer lead pitch is 0.25
