First IC cent. X\Y:
IC center coordinate in the left bottom of IC array, it can input
manually or determine by location;
(2)
Last IC cent. X\Y:
IC center coordinate in the top right of IC array, it can input
manually or determine by location;
(3)
X\Y direction cnt: i.e. IC count in X\Y direction;
(4)
Start IC num.:
ICs are numbered(start from 0) from left to right and down to top, if
the start IC number is set, ICs which number smaller than start IC number will be
skipped.
Note, IC tray can not be put on the top of fix pillar, or pull needle may run into IC tray
