AMAT 0190-49518 Power PMAC 465 CPU Board

Description

Product Introduction

Applied Materials 0190-49518 is identified by multiple independent parts sources as a Power PMAC 465 CPU assembly, associated with Delta Tau Data Systems P/N 604055-101. wSemi’s historical transaction data records the part as an “Applied Materials 0190-49518 Delta Tau Data Systems Power PMAC 465 CPU Board,” while another listing identifies it as PCB ASSY, POWER PMAC 465 CPU, 604055-101.

The Power PMAC platform is associated with machine-control and motion-control applications. In an Applied Materials tool, however, the AMAT part number is the critical procurement identifier. A generic Power PMAC or CPCI controller should not be considered interchangeable simply because its processor or mechanical format appears similar.

The strongest available evidence therefore supports the identification:

AMAT 0190-49518 → Delta Tau Power PMAC 465 → 604055-101.

Specification Integrity Warning

Do not populate a product page with detailed processor, memory, storage, Ethernet, serial, bus, or power specifications simply because they appear on generic Power PMAC documentation.

The evidence available here confirms the Power PMAC 465 / 604055-101 identity, but does not establish that every published Power PMAC 465 specification applies to the exact Applied Materials configuration.

For an AMAT spare, configuration-specific information takes priority over generic controller-family specifications.

 

Functional Role

The 0190-49518 is best treated as a CPU/control assembly, rather than an analog I/O card or RF power component.

The Power PMAC architecture is designed for machine and motion control. In semiconductor equipment, that can place the CPU at a high level in the control hierarchy.

A CPU-board failure can therefore produce symptoms that look like multiple downstream hardware failures:

• Controller does not initialize
• Motion subsystem does not start
• Equipment sequence cannot proceed
• Multiple communication faults appear simultaneously
• Axis or actuator control becomes unavailable
• Equipment software cannot establish normal controller communication

The actual tool-level function remains configuration-dependent.

Field Troubleshooting

1. Establish the Scope of the Failure

Before replacing 0190-49518, determine whether the failure is:

• CPU-only
• Motion-control related
• Communication-related
• Power-related
• Backplane-related
• Software/configuration-related

If several subsystems fail simultaneously, investigate the controller power and infrastructure first.

2. Verify Controller Power

Check the applicable controller power rails and system power distribution before condemning the CPU.

A low or unstable supply can create:

• Failed boot
• Random resets
• Communication loss
• Processor watchdog events
• Intermittent operation

3. Inspect the CPCI Connection

Because the part is identified as a Power PMAC CPCI 465 assembly, inspect the board-to-backplane interface carefully.

Look for:

• Contaminated contacts
• Bent connector pins
• Mechanical damage
• Loose seating
• Signs of overheating
• Backplane abnormalities

Do not repeatedly reseat an energized board.

4. Compare With a Known-Good Controller

If a validated spare is available, document the existing configuration before substitution.

Record:

• AMAT P/N
• Delta Tau P/N
• Board revision
• Software/firmware information
• Connector arrangement
• Existing controller alarms
• Equipment configuration

Then perform a controlled substitution.

 

Incoming Inspection and QA SOP

For an incoming AMAT 0190-49518 spare:

Inspection	Acceptance Criteria
AMAT label	0190-49518
Delta Tau identification	604055-101 where applicable
Controller model	Power PMAC 465
PCB condition	No cracks, corrosion, burns, or missing components
CPCI connector	No bent or damaged contacts
Component condition	No obvious overheating or mechanical damage
Revision	Recorded and compared with installed unit
ESD packaging	Proper ESD protection
Functional test	Preferably performed in compatible equipment
Boot test	Controller initialization verified where test capability exists
Communication test	Required controller communications verified
Condition	New Surplus / Used Tested / Refurbished / Untested
Warranty	Written terms confirmed

A visual inspection should not be described as a functional test.

For a CPU controller, the preferred acceptance test should establish that the unit actually boots and communicates correctly in a compatible test environment.

 

⚠️ Veteran’s Tech Trap Guide

Trap 1 — Believing the RF Power Description

Several reseller pages currently describe 0190-49518 as an RF power generator or multi-band RF module. That conflicts with multiple direct listings identifying the exact number as a Power PMAC 465 CPU / 604055-101 assembly.

Do not use claims such as 13.56 MHz, 5 kW, RF matching, or plasma-power specifications in the product specification for 0190-49518 without primary documentation.

Trap 2 — Confusing Power PMAC 465 With Any Power PMAC Controller

The controller family is not enough for substitution.

The correct procurement chain is:

AMAT P/N → Delta Tau P/N → controller model → board revision → tool configuration.

Trap 3 — Ignoring Software and Firmware

A CPU replacement can be electrically functional and still fail to restore the equipment if its software, firmware, configuration, or application environment does not match the installed system.

Trap 4 — Treating “CPCI Compatible” as “AMAT Compatible”

Mechanical and bus compatibility does not establish equipment compatibility.

The AMAT-specific part number should remain the primary replacement criterion.

 

Spare-Inventory Strategy

Because 0190-49518 is a CPU/control assembly, its inventory criticality should normally be higher than that of a low-cost passive component.

For a single critical tool, a reasonable minimum strategy is:

• 1 installed
• 1 validated spare
• Repair candidate only as additional contingency

For multiple tools, first establish whether the same 0190-49518 / 604055-101 configuration is genuinely interchangeable.

Inventory records should include:

• AMAT P/N
• Delta Tau P/N
• Controller model
• PCB revision
• Serial number
• Compatible equipment
• Firmware/software status
• Functional-test date
• Condition
• Warranty expiration
• Storage location

This avoids a common legacy-equipment problem: having a technically similar CPU in stock that cannot be deployed without additional qualification.

 

New Surplus vs. Used vs. Refurbished

New Surplus

Check:

• Original AMAT identification
• Delta Tau P/N
• Board revision
• Packaging
• Signs of prior installation
• Connector condition

Do not assume “new surplus” means configuration-verified.

Used Tested

A tested used controller can be a practical choice for legacy equipment.

Require the supplier to specify what “tested” means. A power-on check is considerably weaker than a boot and communication test.

Refurbished

Ask whether refurbishment involved:

• Component replacement
• Connector repair
• Solder rework
• Firmware verification
• Functional testing
• Burn-in

Untested / As-Is

Treat an untested CPU board as a repair candidate rather than a production-ready spare.

J316Gallery currently lists 0190-49518 inventory as pre-owned, with its standard listing condition language indicating untested/as-is/no warranty.

Other historical listings show that working units have also circulated in the secondary market, demonstrating that condition varies substantially between suppliers.
