Prepare Input/Output Modules

CAUTION: Devices programmed on the PS288 may be highly sen-

sitive to internal damage from electrostatic discharge (ESD). To

prevent damage from ESD, always wear an antistatic wrist strap.

The wrist strap should be connected to the grounding socket and

should contain a 1M-ohm (minimum value) to 10M-ohm (maximum

value) current limiting resistor.

Regardless of input module used, all devices should be installed

right-side-up (“live bug” orientation), with the device leads pointing toward

the floor so that identifying marks are visible on the top of the device.

The system must be reconfigured if a different device type is programmed or

if the input module (tube, tape, or tray) changes.

When a device is in the pick position waiting for the PNP head, pin 1 on the

device must match the pin 1 orientation predefined in the job. If it does not,

when the PNP head picks the device and rotates it based on the information

in the job, the device might be inserted incorrectly in the socket, possibly

damaging device leads and socket contacts.

NOTE: Ask your system administrator for pin 1 orientation for

trays and tape input as defined by your facility.

CAUTION: Devices and the sockets can be damaged if the devices

at the pick position do not match the pin 1 orientation defined in the

job. Make certain that they are the same. If they are not, do not start

the job until you reinstall the devices in the input module or modify

the job.

If the devices require a different size probe tip, make sure that you install the

appropriate probe tip onto the PNP head as shown below:

Figure 3-14—Selecting probe tip size

For instructions on how to set up the static tray input/output module, see

“Setting Up Static Tray Input/Output” on page 2-5.

If processing this device type: Use this size probe tip:

Small (2 mm)

300 mil DIP

20 PLCC

32 TSOP

Medium (4 mm)

28 PLCC or greater

40 TSOP or greater

Run a Job

WARNING: Do not continue until making sure that all safety

shields are closed, or personal injury may result.

1. From the Setup window, click Run.

Operation • Operator Functions

3—10 PS288 Owner’s Manual

2. On the Run window, click Run.

Figure 3-16— Click Run on the Run window

The PNP head moves to the Park position and then starts the Job. Status

indicators appear inside the programmer outlines, and PNP head loca-

tion is tracked on the Run window.

NOTE: If the input/output media are tubes, you may need to adjust

tube vibration if devices do not move easily. Use the vibration con-

trols on the front of the PS288 to adjust tube vibration.

NOTE: To end a Job after the “pass” media is full, click Stop Input

to the ON position.The Stop Input switch can be selected while a

Job is running. If there are more devices in sockets than empty

spaces in the “pass” media, the system will load an additional tray

or tube before stopping. You can continue a Job stopped in this way

by clicking Run again.

Stop the System

There are three methods for stopping the PS288:

• Emergency Stop and Restart — Stop the movement of the PNP head

in an emergency.

• Pause a Programming Session — Pause a programming session to

perform routine tasks and then resume the programming session.

• End a Job — Complete the current programming cycle, remove

devices from the sockets, and place them into the output media (pass or

reject).

Emergency Stop and Restart

To prevent bodily injury or damage to equipment in an emergency, press

either of the red Emergency Stop (E-Stop) buttons located on the upper
