Bonding pad geometry for the IBIS4-1300
• The 84 pins are distributed evenly around the perimeter of
the Chip. At each edge there are 21 pins. Pin 1 is (in this
drawing) in the middle of the left edge.
• The opening in the bonding pads (the useful area for
bonding) is 200 x 150 um.
• The centers of the bonding pads are at all four edges at 150
um distance from the nominal chip border.
• The scribe line (=the spacing between the nominal borders
of neighboring chips) is 250 um.
• The bonding pad pitch is 437 um in X-direction
• The bonding pad pitch in Y-direction is 393 um
