Chapter

4System Theory

The PS288 consists of various electrical and mechanical systems which pro-

vide facilities for—or perform a portion of—the overall operation of the

machine. Their operation and relationship with the other components of the

system are described in this chapter.

Main Power

System

The main power system provides primary and generated voltages for use

within the PS288. Input power is received from the input panel on the rear of

the machine. It is a 208–240 VAC, 50/60 Hz, 30A circuit.

Circuit Breakers

208–240 VAC is provided to the programmer power supplies, gantry servo

motor amplifiers, and the I/O Controller. The two circuit breakers on the

input panel provide circuit protection for the main power input and the gan-

try servo amplifiers.

I/O Controller

The I/O Controller provides 115 VAC, 60 Hz, for all other systems in the

PS288 including, but not limited to, the Handler Computer, video monitor,

and programmer power supplies. Additionally, the I/O Controller provides a

power-on control signal to the servo motor power contactor, allowing the

208–240 VAC to be applied to the gantry’s X and Y servo motor amplifiers

and two low voltage systems used for sensor power and PNP head motor

drivers. See Figure 4-1.

4—2 PS288 Owner’s Manual

The I/O Controller also provides an interface for all sensor systems, several

visual indicators, and power and control of other systems throughout the

PS288. Sensor conditions are reported back to the Handler Computer

through a series of connections on the rear of the I/O Controller. Connections

supported by the I/O Controller include:

• Air pressure sensors

• Light tower

• Tube vibration assemblies

• Component position optics

• Vacuum and pressure control solenoids and sensors

• Safety shield interlocks

• Tape output control and associated sensors

• Power contactor for the laser marking stage

• Label and laser marking system controls and associated sensors

• Additional connectivity for future options

For a listing of status indicator lights on the I/O Controller, see Appendix A,

“I/O Controller LED Status.”

System Theory • FlashCORE Programmer

PS288 Owner’s Manual 4—3

FlashCORE programmers on the PS288 are made up of the following com-

ponents:

CPU - PowerPC Controller Board (RPX-Lite)

The PowerPC Controller Board is based on MCP850 PowerPC CPU and

includes many hardware elements, like 10 Base-t Ethernet port and a

PCMCIA interface.

It has a memory controller that allows the device programming algorithm to

control the bus cycle timing for the memory range used for programming.

The onboard I2C bus is used to address a serial EEPROM on the adapter

board of the programmer to collect statistics on a given socket. The I2C bus

is also used on the RPX Lite Board to address the temperature and thermal

monitor (STTM) and another onboard serial EEPROM used for RPX config-

uration storage.

Waveform Board

The core of the FlashCORE programmer design, the Waveform Board inter-

faces to the PowerPC Controller Board with two programmable logic

devices: a CPLD (non-volatile) and a FPGA (volatile). These two logic

devices make up the basic programmer control circuitry. The CPLD contains

logic to control the communications interfaces as well as the analog controls

of the programmer and configuration of the volatile FPGA. The FPGA is

used to route address, data and control signals from the PowerPC to the

devices in socket, and provide Device Insertion, V

waveform generation,

and Self-test circuit control logic.

Backplane Board

The Backplane Board is a connection scheme to connect the Waveform

Board to the Socket Adapter board. In addition to supplying connections

between the two boards, it also supplies the circuitry for address line buffer-

ing to isolate each device so that a failing part cannot affect non-failing

devices and power and ground switching relays.

Socket Adapter Board

The Socket Adapter Board connects to the Backplane Board to supply the

electrical connections for programming to the individual sockets. It also con-

tains a 10 bit ID bus used to identify the adapter installed. A small EEPROM

exists on this board for maintaining socket cycle counts for this physical

adapter. By putting this EEPROM on the adapter itself, the socket cycle

counts for a specific Socket Adapter Board can be tracked independent of

the FlashCORE programmer it has been installed on.

In each FlashCORE programmer, there is a PCMCIA card that acts as the

local drive for the FlashCORE programmer. There are various sub-directo-

ries and files on this, as shown in Figure 4-2.

Power to FlashCORE programmers is provided by a universal power supply,

which powers two FlashCORE programmers.
