High-Precision Linear Motion Solutions for Semiconductor Wafer Handling and FPD Inspection

High-Precision Linear Motion for Semiconductor and FPD Applications

Semiconductor manufacturing and flat panel display (FPD) inspection demand motion components that deliver uncompromising accuracy at every step — wafer transfer, die bonding, lithography alignment, and optical inspection all hinge on repeatable, vibration-free positioning.

At Jufeng Jingke Automation, our JFJK series ball screw linear actuators are purpose-built for these precision-critical environments.

Key Performance Characteristics:

- Repeatability: ±0.01 mm — ensuring consistent positioning across thousands of wafer handling cycles. In semiconductor processes, even a few microns of drift can mean yield loss across an entire batch.

- Low Particulate Emission: While cleanroom environments are already controlled, our ball screw modules are assembled with low-outgassing lubricants and minimal particle-generating components, reducing contamination risk to sensitive wafer surfaces without relying on external enclosures.

- High Rigidity and Low Vibration: The ball screw design provides superior stiffness compared to belt-driven alternatives. Minimal vibration during acceleration and deceleration ensures stable imaging in FPD inspection and precise force control in probe testing.

- Smooth Velocity Control: Available with a range of lead options (5mm to 32mm), our actuators support both high-speed wafer transfer and slow, controlled motion for delicate alignment tasks — all from the same platform family.

- Customizable Configurations: Stroke length, motor mounting, multi-axis XY/XYZ gantry integration, and special material options are available to match your specific equipment footprint and process requirements.

Why Ball Screw over Belt Drive for Semiconductor?

Belt-driven modules, while fast and economical, introduce micro-fluctuations in velocity due to belt elasticity and tooth engagement. For applications where positioning must be deterministic and repeatable to within hundreds of servo counts, only a rigid ball screw drive provides the necessary motion fidelity.

Our engineering team provides 2D/3D CAD models and full technical documentation before order confirmation — ensuring your integration team has everything needed for a seamless design-in.
