Nikon 4S008-036 | EP-X4 Processor PCB Card

Description

Product Overview

Processor-board failures in semiconductor manufacturing equipment can interrupt machine control, prevent startup, or complicate fault isolation. The Nikon Precision 4S008-036 is identified in parts references as an EP-X4 processor printed circuit board (PCB) card, with Intel part number 500201942. This identification places it within the electronics used in Nikon semiconductor equipment rather than a general-purpose PLC or DCS platform. The board’s exact processing responsibilities, onboard components, and supported equipment configurations should be established from the original machine documentation and the physical assembly label before a replacement is approved.

Within semiconductor manufacturing systems, processor boards typically participate in equipment-level control, data processing, or coordination between electronic subsystems. The specific role of the Nikon Precision 4S008-036 should not be inferred from its processor-board classification alone. Compatibility can depend on the host machine model, board revision, installed firmware, connector arrangement, and associated interface circuitry. The related designation 4S008-036AN appears in parts listings, but the relationship between this suffix and the base model should be verified before treating the assemblies as interchangeable. Likewise, the Intel part number 500201942 is a useful identification cross-reference, not proof that a board with a similar processor or component layout will operate correctly in the target machine.

For maintenance and procurement teams, the Nikon Precision 4S008-036 is most relevant when restoring equipment that was originally configured for this board. Before ordering, record the complete part number, revision markings, connector layout, and host equipment identification. If the removed board is available, compare its physical features and inspect for component damage, corrosion, or signs of previous repair. A replacement should also be checked against the equipment’s approved service procedure, including any required configuration restoration or functional verification. These steps reduce the risk of installing a physically similar board that is electrically or functionally incompatible. For older semiconductor equipment, documented testing and traceable hardware identification are more useful procurement criteria than appearance alone.

Product Introduction (Non-Templated)

A processor PCB can look correct and still fail to initialize the host machine if its revision or configuration differs. The Nikon Precision 4S008-036, identified as the EP-X4 processor card, carries the cross-reference 500201942. Confirm both identifiers against the original assembly before ordering.

For semiconductor equipment repair, compare the board label, connector layout, and hardware revision. Request a documented functional test when purchasing used or surplus stock, particularly if the replacement will be installed in production equipment.

Key Technical Specifications

The available identification supports the board designation and cross-reference, but does not establish electrical ratings, detailed processing functions, or compatibility with a particular Nikon machine.

Frequently Asked Questions (FAQ)

1. What is the Nikon Precision 4S008-036 used for?

The 4S008-036 is identified as an EP-X4 processor PCB card for Nikon semiconductor equipment. Its precise control or processing duties depend on the host machine and equipment configuration. Confirm the machine model and original board documentation before assigning a more specific function.

2. Is 4S008-036 the same as Intel part number 500201942?

Available parts references associate 4S008-036 with Intel part number 500201942. This cross-reference helps with identification, but it does not independently establish that every assembly bearing one designation has the same revision or configuration. Compare the physical label and board markings before purchase.

3. Can I replace 4S008-036 with 4S008-036AN?

Do not assume that the two designations are interchangeable. The suffix may identify a distinct revision or assembly configuration, and the available references do not conclusively establish equivalence.

Before installation:

• Compare both complete part numbers.
• Check board revision and component markings.
• Verify the host equipment’s approved parts list.
• Follow the required post-replacement functional checks.

4. Does 4S008-036 support a specific firmware version?

A supported firmware version has not been verified for this board. Compatibility may depend on the host equipment model, controller or processor configuration, board revision, and installed software release.

Obtain the applicable service documentation and confirm the required firmware before installation. Do not infer software compatibility from a matching PCB part number alone.

5. How can I verify a new-surplus Nikon 4S008-036?

New-surplus status indicates a claimed inventory condition, not proof of operational performance. Ask the supplier for clear label photographs, revision details, storage history, and a test report.

For a processor PCB, useful testing evidence should identify the test setup, equipment configuration, observed startup behavior, and any diagnostic faults. Confirm warranty coverage in writing, especially when the original equipment is no longer supported by routine production service.

6. Will replacing the 4S008-036 erase machine settings or control logic?

That depends on the equipment architecture. Some settings may reside on separate storage devices or controller hardware; others may depend on data retained by the original board or host system. The exact arrangement for this model has not been verified.

Back up machine configuration and other recoverable data where the approved service procedure permits. Establish whether board replacement requires parameter restoration, calibration, or software initialization before removing the original assembly.

7. What warranty should I request for a replacement 4S008-036?

Request written confirmation of the warranty period, coverage for functional defects, return conditions, and any exclusions for installation or equipment-related faults. If the board is sold as tested-working or refurbished, ask what tests were performed and whether the report corresponds to the actual unit supplied.

For production-critical semiconductor equipment, a traceable serial number, revision identification, and documented functional test provide useful evidence when evaluating replacement stock.

Procurement recommendation: Use Nikon Precision 4S008-036 / EP-X4 / 500201942 as the initial identification set. Before publishing definitive specifications or approving a purchase, confirm the board revision, host equipment model, and condition of the actual unit.
