Static tray mount—
Using positioning pins and “L” bracket magnets, holds several differ-
ent tray sizes including JEDEC and non-JEDEC standard trays in posi-
tion for the PNP to pick up devices and return them after processing.
I/O Controller—
Provides 115 VAC for the Handler Computer and associated compo-
nents, as well as the PNP head. Also provides 24VDC for the various
sensor systems throughout the PS288. The I/O Controller provides a
transfer point for all sensor signals within the PS288 and optional
assemblies, and sends the signals to the Handler Computer for process-
ing.
Handler Computer—
The Handler Computer operates using the Microsoft
®
Windows XP
operating system. It hosts TaskLink and AH500 operating software for
the PS288, monitors all sensors, and hosts the vision system.
CAUTION: The PS288 should never have software added unless
instructed to do so by Data I/O Customer Support. Adding software
to the PS288 can cause damage and/or cause the system to operate
improperly. Adding software without specific instruction from
Data I/O Customer Support will void the warranty and may incur
service charges.
Keyboard and touchpad—
Used to set up system operation. Can be used instead of the touch
screen monitor if desired.
Grounding socket—
Used to prevent damage to devices from electrostatic discharge (ESD).
Operators should wear an antistatic wrist strap inserted in the ground-
ing socket.
Touch screen monitor—
Central display mechanism for the PS288, shows system status and
information about programming jobs and vision system. The touch
screen may be used instead of the keyboard and touchpad if desired.
NOTE: Throughout this manual, the term “click” is used to mean
“touch” when using the touch screen monitor.
Safety shields—
Used to protect against personnel and equipment damage when the
PNP head is in motion. Safety interlocks on the safety shields stop
movement of the gantry and PNP head if the shields are opened or
removed while the gantry is in operation.

PS288 Owner’s Manual 1—7
Marking system (optional; not shown)—
A label marking or laser marking system used to mark devices so they
may be identified at a later time. Installed in the Option Bay on the
right rear of the PS288.
The marking system uses a shuttle transfer assembly to move devices
to and from the marking stage. The shuttle transfer is a belt-driven
shuttle system that has two pedestals for holding devices. Initially, a
device is placed in the second pedestal and is transported to the mark-
ing area. After the device is marked, the shuttle moves it back to the
second pedestal. The PNP head places an unmarked device in the first
pedestal and then removes the marked device from the second pedestal
and routes it to the tray or tube output module. The device in the first
pedestal is then marked. This process continues, and alternates pedes-
tals throughout the remainder of the Job.
If the tape output system is selected, then only one of the pedestals is
used. Since both the marking system and the tape output system are
placed in the Option Bay on the rear of the PS288, both pedestals can-
not be used. Additionally, if the devices are marked with the label
printing system, only one pedestal is utilized.
The laser marking system uses a CO
2
laser to mark parts. The laser
applies a user-defined mark that can include letters, numbers, or draw-
ings. The laser marking system operates as a Class 1 laser system
(CDRH classification), and therefore uses integrated interlocks to pre-
vent the laser from firing while any cover is open. The laser should
never be operated without safety covers in place.
WARNING: Blindness hazard! Always wear eye protection when
the laser safety shields are open, such as during service. Direct or
diffuse laser radiation can damage eyes. Goggles must block
10.6 µm laser radiation. Goggles protect against scattered energy
but not against direct viewing of the laser beam or reflections
from metallic surfaces.
WARNING: Serious burn hazard! Direct or diffuse laser radia-
tion can cause serious burns. Keep hands and other parts of the
body out of the path of the laser bean when servicing.
WARNING: Toxic fume hazard! Laser marking generates vapors,
fumes, and particles that may be noxious, toxic, or even fatal.
Follow maintenance procedures on the fume extractor. Use
proper ventilation.
For additional safety information, see “Laser Safety” on page 1-16.

Automatic tray feeder (optional; not shown)—
TF20 and TF30 automatic tray feeders are available as options.
Designed to automatically supply devices in trays to the PS288, the
TF20 accepts thin or thick JEDEC trays only and the TF30 accepts
semi-vendor matrix trays including JEDEC.
Tube input (optional; not shown)—
Tube input uses tubes to provide blank devices to the system for pro-
gramming. Vibration mechanisms keep devices sliding freely by gently
vibrating the tubes to reduce the likelihood of device jams.
Tube output (optional; not shown)—
Tube output uses tubes to collect devices following programming.
Vibration mechanisms keep devices sliding freely by gently vibrating
the tubes to reduce the likelihood of device jams.
Vibration adjustment controls (optional; not shown)—
Located on the front of the PS288 when the optional tube input or out-
put modules are installed, the vibration adjustment controls are used to
control vibration the tubes receive to reduce the likelihood of device
jams when unloading or loading the tubes.
Tape input (optional; not shown)—
Tape input uses a reel of sealed carrier tape containing unprogrammed
devices to provide devices for programming. Each device is picked
from a carrier tape pocket and placed into a programming socket after
alignment by the vision system. A sprocket wheel advances the tape
one carrier pocket to align the next device into the pick position. As the
carrier tape advances, the cover tape is peeled off so that the PNP head
can pick up the device.
Tape output (optional; not shown)—
Tape output uses a reel of empty carrier tape to hold devices after they
are programmed. Each programmed device is placed into an empty
pocket on the carrier tape. The carrier tape then advances through
either a heat seal or pressure seal unit that applies cover tape to the
filled carrier tape.
Fume extractor (optional; not shown)—
Used with the laser marking option, the fume extractor removes harm-
ful smoke and hazardous materials from the marking area and safely
stores them for proper disposal.
WARNING: Laser marking generates vapors, fumes, and parti-
cles that may be noxious, toxic, or even fatal. The fume extractor
is required for use with the laser marking option and must not be
disabled. Analysis of filter contents obtained following marking a
representative variety of devices has revealed a sufficient level of
hazardous materials, such as antimony and other heavy metals, to
require that the filter be treated as hazardous waste. Filters must
