Chapter

1Introduction

The PS288 is a versatile production programmer that handles traditional and

fine-pitched packages. Its flexibility is due to modular design, allowing you

to optimize for the level of production required by your facility.

PS288 features include:

• Automated programming, handling, and labeling for µBGA, PGA,

QFP, TQFP, TSOP, SOIC, PLCC, DIP, and other packages

• Configured with four FlashCORE programmers

• Support for memory and microcontroller devices in many package

types

• Optical vision system

• Flexible input and output options include static tray, automatic tray

feeder, tube, and tape systems

• Label or laser marking

• Modular design allows configuration for a wide range of applications

• Small mechanical footprint

System

Description

The PS288 moves devices from input media through a programming and

marking process to output media for delivery to the next phase of the pro-

duction process. It combines a device programming system and a high-speed

pick and place head (PNP head) to provide rapid programming of standard

pitch devices, as well as ultra-fine pitched devices.

TaskLink

™

software and Automated Handler (AH500) software running on

the system’s Handler Computer direct the PS288 to perform a series of pro-

cesses, including automatic handling, programming, marking, and place-

ment of devices in the output media of choice. Operator interaction is

reduced by allowing the selection of a Job from a list and starting the system.

Terms Used to Indicate Direction

The PS288 motion system operates on three primary axes: X, Y, Z. These

axes are used throughout this manual to describe the motion of the various

parts of the system, and are described relative to the front of the PS288.

Introduction • Subassemblies

PS288 Owner’s Manual 1—3

An additional axis, called the R-axis (theta), is used to adjust the angular

(rotational) position of devices by the PNP head.

Four Basic Operations

The PS288 performs four basic operations when processing devices:

1. Unload 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 in a programming

socket for programming or on the shuttle pedestal for marking.

2. Program devices—

Devices in the programming sockets go through a series of pre-pro-

gramming tests to make certain they are blank and are correctly

inserted in the sockets. If the tests are successful, the devices are pro-

grammed with the data contained in programmer RAM using an algo-

rithm approved by the semiconductor manufacturer. Data in devices

that pass the programming operation are verified against the RAM data

to ensure that they have been programmed correctly. Testing, program-

ming, and verifying options can be changed from the default settings

using TaskLink software.

3. (Optional) Mark devices—

When marking is selected, devices that pass the programming and veri-

fication operations are moved to a pedestal on the shuttle transfer

assembly, then to the label marker or laser marker where they are

marked for identification.

4. Load devices onto the output media—

Devices are moved by the PNP head from the programming socket or

the marking stage and placed in either trays, tubes, or tape. Devices that

failed the programming operation or subsequent verification are trans-

ported to a dedicated reject tray or other reject module where they are

held for failure analysis or other disposition.

Subassemblies

The PS288 has several subassemblies that work together to provide for

proper operation. Refer to Figure 1-2 for the physical location on the PS288

of the primary subassemblies. (Some of these assemblies are optional and

are not shown in Figure 1-2).
