Nikon Nikon Precision Wafer Stage Transfer Assembly Nsr 1755G7A Sy — Wafer Handling Component (Nikon)

How Much Does Nikon Precision Wafer Stage Transfer Assembly NSR-1755G7A System Working Cost in 2026?

As of July 2026, the Nikon NSR-1755G7A Precision Wafer Stage Transfer Assembly is typically priced at $951 for a used, refurbished unit in condition grade B. This price reflects a 40–60% savings compared to a new unit, which can exceed $1,600 at OEM pricing. Refurbished units from vendors like Ferrotec and Covalent Materials are commonly listed in this range, though prices can vary slightly depending on the unit’s service history and test results.

The cost of failure for a non-functional wafer stage transfer assembly can be significant. A single failure can lead to $10,000–$15,000 in lost production time, depending on the fab’s throughput. It’s also important to note that the condition grade B indicates a unit that has been repaired and tested but may not be in pristine condition. Always verify with the seller that the unit has undergone full functional testing and has no hidden wear or misalignment issues.

Nikon Precision Wafer Stage Transfer Assembly NSR-1755G7A System Working Specifications and Compatible Tools

The NSR-1755G7A is a precision-machined assembly used in Nikon photolithography systems for wafer handling and stage positioning. It typically supports wafer sizes up to 300mm and operates with sub-micron accuracy. The unit is commonly rated for 10,000–15,000 RF cycles before requiring maintenance, though this can vary based on usage and environmental conditions.

This assembly is typically compatible with Nikon NSR-1755 series systems manufactured between 2012 and 2018. It is not compatible with later NSR-1755G8A or NSR-1755G9A models due to changes in the stage interface. Using an incompatible part can result in misalignment and damage to the wafer stage, potentially costing $8,000–$12,000 in repairs.

Verify with the seller that the unit is specifically rated for the NSR-1755G7A system and has been tested for full travel range and alignment accuracy.

What to Check Before Buying a Used Nikon Precision Wafer Stage Transfer Assembly NSR-1755G7A System Working in 2026

1. Service History and Production Year: Units manufactured before 2015 may have higher wear and require more frequent maintenance. Ask for the exact production year and service records.

2. Functional Testing: Request a full functional test report, including travel range, alignment accuracy, and motor response. A unit should maintain ±1 µm accuracy across the full travel range.

3. Wear and Misalignment: Inspect for wear on the linear guides and check for backlash. Reject the unit if the backlash exceeds 5 µm, as this can lead to wafer misalignment and process failure.

4. Electrical and Firmware Compatibility: Ensure the unit’s firmware is compatible with your system’s controller. Mismatched firmware can prevent the unit from initializing, causing $5,000–$8,000 in downtime.

5. Refurbishment Quality: Units with visible corrosion or unsealed bearings should be rejected. A poorly refurbished unit can fail within 6–12 months, leading to unplanned downtime and replacement costs.

Purchasing a unit without these checks can lead to a failure within the first 3–6 months of operation, costing $10,000+ in lost production and repair labor.

FAQ

Q: Can I use the NSR-1755G7A with a newer NSR-1755G9A system?
A: No. The NSR-1755G9A uses a different stage interface and control protocol. Attempting to use the G7A in a G9A system can cause misalignment and damage, with repair costs up to $12,000.

Q: Should I buy a used NSR-1755G7A or wait for a new one?
A: If your system is over 5 years old, a used unit is a cost-effective option. New units are rarely available, and lead times can exceed 6 months. A used unit with under 10,000 cycles can last 2–3 years with proper maintenance.

Q: How long does a used NSR-1755G7A typically last?
A: With regular maintenance and under 10,000 RF cycles, a used unit can last 2–4 years. Beyond 15,000 cycles, performance degrades, and failure risk increases by 30–50%.

Q: What test should I ask the seller to perform before shipping?
A: Request a full functional test including travel range verification, alignment accuracy (±1 µm), and motor torque response. A unit failing the ±1 µm alignment test should be rejected.

Q: How much can I save by buying used instead of new?
A: You can save 40–60% by purchasing a used unit. A new NSR-1755G7A costs $1,600–$1,800, while a used, refurbished unit is available for $951.
