Electrostatic Discharge (ESD) Precautions
Devices processed on the PS Machine are very sensitive to static, and
could be damaged by unintended electrostatic discharge while being
handled. The most effective way to prevent damage from ESD is to
make sure a common electric potential (ground) exists between a
static-sensitive device or component, its environment, and the oper-
ator.
Operators should wear an antistatic wrist strap connected to the
grounding connection on the front of the PS Machine. The wrist strap
should contain a 1–10 M-ohm current limiting resistor.
Handling Devices Safely
To prevent damage to device pins, use a vacuum tool, also called a
vacuum tweezer, to pick up devices. The vacuum tool is designed to
handle devices without damaging them.
CAUTION: Possible device pin damage. Do not touch devices
with your hands or any implement other than the vacuum tool.
Damage to devices with fine-pitched leads may result.
To pick up a device using the vacuum tools use an squeezable air
bladder for suction. There are a variety of models, sizes and tips.
Some tips are replaceable.

[Laser Marking only] Fume Extractor
Used with the Laser Marking option, the laser fume extractor
removes harmful smoke and hazardous materials from the marking
area and safely stores them for proper disposal.
Note: See Laser Safety on page 1-24 for more information.

Machine Axes
The PS System gantry operates on three primary axes: X, Y, Z. An
additional axis, called the R-axis (theta), is used by the PNP head to
change device orientation (rotation).
Figure 1-1: These axes are used throughout this manual to describe
motion or direction of components of the PS System. They are the
same for all PS Machines. (PS388 shown.)
Four Basic Operations
The PS System performs four basic operations when processing
devices:
1. Pick devices from the input media—
The pick and place head (PNP head) unloads devices from the input
tube, tray, or tape module. These devices are placed into program-
ming sockets in all cases except when Ignore Programmers is selected,
in which case the head may take devices directly to a different media
(repackaging only) or to the shuttle pedestal for marking only.
2. Process devices—
Devices in the programming sockets undergo any or all of the fol-
lowing processes as determined by the job. These processes are set in
TaskLink.
• Continuity check
There’s a glossary (just
before the index) of
terms related to pro-
gramming with the
PS System.

3. (Optional) ICOS System device inspect
Inspection system by ICOS detects bent leads on devices prior to fur-
ther processing.
4. (Optional) Mark devices—
When marking is selected, devices that pass the programming and
verification operations are moved to a pedestal on the Shuttle
Transfer Assembly which delivers them to a Label Marker or Laser
Marker where they are marked for identification.
5. Load devices into the output media—
Devices are moved by the PNP head from the programming socket or
the marking pedestal and placed in output media: trays, tubes, or
tape. Devices that failed the programming operation or subsequent
verification are delivered to a dedicated Reject Bin or other reject
module where they are held for failure analysis or other disposition.
Input and Output Options
PS System input and output options are: static tray (manual), tray
feeder (automatic), tube, and tape.
Any combination of input and output options may be used. For
example, the PS System can be configured with input as static tray
and output as tube, or input as tape and output as static tray.
