Mask Aligner

About the Machine

The XRD Mask Aligner is a precision system for aligning frames, masks, stamps, and image patterns with micron-level accuracy. It combines AI-based vision, optical inspection, and X-Y skew positioning to ensure accurate alignment, lamination, image transfer, and UV curing across R&D and manufacturing applications.

 

Objective of the Machine

The Xma is designed to perform the following core objectives:

• Align the mask window with the mounting frame.

• Position images on nickel shims and PET films within the mask window.

• Laminate transparent PET stamps to the mask window.

• Transfer images from PET/nickel shims to the mask window.

 

Key Components of the Machine

• Alignment System: HD camera with X, Y, and skew adjustments for precise positioning through a micrometre.

• Stamping/Bonding Mechanism: Rubber nip roller for uniform spreading of UV resin, air removal, and uniform bonding.

• Pneumatic System: Pneumatic cylinder for nipping and mask pressing.

• UV Curing Module: Phoseon UV LED source for controlled resin curing.

• User Interface: Live HMI with PC connectivity.

• Inspection System: Vision-based system that automatically detects alignment marks and provides real-time positioning feedback for accurate alignment.
