LIFT NEEDLES
Eject Head Needles are raised. No software adjustment necessary,
however, the needle height may need adjustment. This is a mechanical
adjustment: to raise the needles turn the Stop Ring on the Eject Actuator
counter clockwise, to lower turn the Stop Ring clockwise.
Note
: Pneumatic Ejectors only, see Motorized Ejector section on page 105 for
details.
6.
WAIT N.NNN SECS FOR DIE TO LIFT.
Displayed time will be the amount of time the Pickup Arm waits in the
current position for the die to be released from the tape. Generally, the
default time of 0.030sec is correct, but larger die may need a longer
amount of time to peel from the tape. This time is adjustable using the
+/ -
keys with the
Coarse/Fine
keys. Run the machine in normal
RUN
Mode
for a few cycles to determine how long the wait time should be.
7.
LIFT TO SEARCH HEIGHT AT 8000 u/sec.
When this is displayed on the LCD you can adjust the speed at which the
pickup head will lift to search height. The range is 100 to 8000 u/sec.
Coarse
will adjust in increments of 1000 and
Fine
will adjust in
increments of 100.
8.
GO UP TO TRAVERSE HEIGHT.
The Pickup Head will rise to
Traverse Height
to clear obstructions when
moving.
If a delayed pick is desired to allow the Gel-pak to peel off the die, set a
search height that is above the
Pick Height
and below the
Traverse
Height
. The Pickup Head will travel to this height at the speed set in the
previous step. If no delay is desired, leave the
Search Height
the same as
the
Pick Height
.
9.
TURN OFF TAPE VACUUM.
The vacuum to the Eject Head is turned
OFF
.
10.
RETRACT NEEDLES.
The air to the Actuator is turned
OFF
and the needles are retracted. This
allows the wafer to be moved to the next die to be picked.
11.
TABLE GO TO PLACE POSITION.
The table will move to the proper position to place the next die. If
inspection options are installed on the system, this step will occur after
the inspections are completed.
