Nikon Nikon Precision Wafer Loader Indexer Lift Assembly Nsr S204B — Used Refurbished Parts for NSR-S204B Lithography Systems (Nikon)

How Much Does Nikon Precision Wafer Loader Indexer Lift Assembly NSR-S204B System Working Cost in 2026?

As of July 2026, the Nikon Precision Wafer Loader Indexer Lift Assembly for the NSR-S204B system is priced at $1,009 for a used, refurbished unit in condition grade B. This price is typically sourced from vendors like Ferrotec and Axus Technology, who specialize in high-volume semiconductor equipment parts. Refurbished units in this price range usually represent a 40–60% cost savings compared to a new OEM replacement, which can exceed $2,500.

The cost of failure for a non-functional or degraded Indexer Lift Assembly can be significant. A failure during wafer loading can cause a full system halt, with downtime costs in 200mm wafer lines averaging $1,200–$1,500 per hour. That means even a 30-minute delay due to a faulty lift assembly could cost a facility over $600 in lost throughput.

Units in condition grade B are typically 10–15 years old, with 10,000–15,000 operational cycles. While they may show signs of wear, they are often fully functional after a standard refurbishment process. However, buyers should be cautious—units with more than 20,000 cycles or signs of mechanical misalignment should be inspected closely before purchase.

Nikon Precision Wafer Loader Indexer Lift Assembly NSR-S204B System Working Specifications and Compatible Tools

The Nikon Precision Wafer Loader Indexer Lift Assembly is a critical component in the NSR-S204B lithography system, used to precisely position and load 200mm wafers into the processing chamber. It typically operates with a vertical stroke of 10–15 mm and a lateral indexing range of 3–5 mm, depending on the system configuration. Lifespan is commonly measured in operational cycles, with most units lasting 10,000–15,000 cycles before requiring service.

This part is compatible with NSR-S204B systems manufactured between 2003 and 2008. It is not compatible with later NSR-S204C or NSR-S205 models due to differences in wafer handling geometry and control interface. Using an incompatible lift assembly can lead to misalignment and wafer breakage, with a single damaged wafer costing $150–$200 in material and rework costs.

Verify with the seller that the unit is specifically rated for the NSR-S204B. Units with mismatched motor or encoder types (e.g., part number NSR-S204C-0212) will not function correctly and may cause system shutdowns.

What to Check Before Buying a Used Nikon Precision Wafer Loader Indexer Lift Assembly NSR-S204B System Working in 2026

1. Cycle Count and Age: Units with more than 20,000 cycles or over 15 years old are high-risk. A unit with 25,000+ cycles is a hard reject due to high wear and potential failure during operation.

2. Mechanical Alignment: Perform a visual and tactile inspection for play in the lift arm or indexing mechanism. Use a dial indicator to check for more than 0.05 mm of deviation. Excessive play can cause wafer misalignment and breakage.

3. Motor and Encoder Functionality: Run a bench test to verify motor torque and encoder feedback. A motor with less than 80% of rated torque should be rejected. Encoder drift beyond 0.1° per cycle can lead to indexing errors and system faults.

4. Control Board Compatibility: Confirm the control board is compatible with the NSR-S204B. Boards from NSR-S204C systems will not work and can cause system lockouts, costing $500–$800 in lost production.

5. Refurbishment Documentation: Ask for a detailed refurbishment report. Units without a clear service history should be avoided. A poorly refurbished unit can fail within the first 100 cycles, leading to unplanned downtime and repair costs.

Purchasing a defective or incompatible unit can result in $1,000–$2,000 in direct costs, including repair labor and lost throughput.

FAQ

Q: Can I use a Nikon NSR-S204B Indexer Lift Assembly in an NSR-S204C system?
A: No. The NSR-S204C uses a different indexing geometry and control protocol. Attempting to install an NSR-S204B unit can cause system errors and wafer breakage, with a single failure costing $200–$300 in material and downtime.

Q: Should I buy a used Nikon NSR-S204B Indexer Lift Assembly with 18,000 cycles?
A: Yes, if it has been recently refurbished and tested. Units with 15,000–20,000 cycles are acceptable if they pass a full bench test. Units with 20,000+ cycles are a high-risk purchase and should be avoided.

Q: How long does a Nikon NSR-S204B Indexer Lift Assembly typically last?
A: With regular maintenance, it can last 10–15 years or 10,000–15,000 cycles. Beyond that, performance degrades, and failure rates increase by 20–30%.

Q: What is the difference between a new and used Nikon NSR-S204B Indexer Lift Assembly?
A: New units cost $2,500–$3,000 and come with a 2-year warranty. Used, refurbished units cost $1,009 and typically offer a 6–12 month warranty. Used units save 40–60% but may require more frequent servicing.

Q: How do I test the motor performance of a used Nikon NSR-S204B Indexer Lift Assembly?
A: Use a motor tester to measure torque output. A healthy motor should deliver at least 80% of the original rated torque. If it drops below 70%, it should be replaced to avoid system failure.
