Application No. 09/044,629
We cannot sustain the examiner's respective rejections of
appellant's claims.
As explained in the specification (pages 4, 7 and 9), a
mated pair of die-level test and burn-in flipping trays is
inverted causing die-level carriers in pockets of the first
tray to transition under the influence of gravity to
corresponding pockets in the second tray in an orientation
inverted about the z-axis. Figs. 6 and 7 show a mated pair of
flipping trays, with Fig. 6 showing a phantom carrier 30 in a
lid down orientation, and Fig. 7 depicting the phantom carrier
30 in a lid up orientation. The specification (page 9) points
out that moving from Fig. 6 to Fig. 7 is merely a matter of
rotating or rolling the mated trays such that the top tray
becomes the bottom tray and vice versa.
Independent claim 9 specifies a method of inverting a
plurality of die-level carriers along a z-axis comprising,
inter alia, depositing the die-level carriers in a first
orientation in a plurality of pockets of a first tray, mating
a second tray with the first tray, and rotating the first and
