Aligning a Device to a PLCC Programming Module
Whenever you run a new TaskLink Task or Kit using a PLCC device, the
display on the 2500 prompts you to align the beam. Follow the procedure
below to adjust the position of the beam so that it picks the device at its
center and inserts the device into the programming module correctly.
Failure to perform the alignment and cleaning procedures may cause
premature wear of the module’s contacts and an eventual decrease in
programming yield.
Note: This alignment procedure assumes that the devices are
square PLCCs,
with pin 1 oriented toward the back of the input track
(away from
the front of the 2500). Alignment of rectangular, 32-pin PLCC devices is
described on page 4-32.
Align Beam to the Device
Follow these steps to align the beam to a device in the input track.
1. Insert a tube of devices into the input track and close the hood.
2. Start the new Task.
3. The beam positions itself over the first device and pauses. The 2500
displays:

4. Press
←
and
→
to center the chuck over the device (left-to-right).
Pressing the arrow key once moves the beam one small step in that
direction.
Note: You can change beam alignment while a Task is running. When the beam
hesitates above the device, press
STOP
and use the front panel arrow keys.
5. Press and hold
D
on the 2500’s keyboard to lower the beam and
check the position of the chuck on the device. For a slower insertion,
lower the beam manually by pushing directly on the top of the beam
assembly, on either side of the beam’s limit bar (the limit bar is shown
in Figure 1-7).
Adjust the left-to-right position as necessary. When the beam is
centered, press
START
.
6. The beam picks up the device, rotates it 90
°
, moves it over the
programming module, and pauses before inserting the device in the
block. The 2500 displays:
Align Device to Module
7. Press
←
and
→
to center the device over the programming module
(left-to-right when you stand in front of the 2500).

8. Press and hold
D
on the 2500’s keyboard to lower the device into the
programming block so you can check the alignment. You may also
lower the beam with your hand by pushing on either side of the
beam’s limit bar (see Figure 1-7). Pushing on the beam head or any
other part of the beam might distort the alignment.
