Alignment Stability Engineering

Alignment Stability for Real Production.

PRT focuses on engineering systems that stabilize material-to-mask alignment. Vision alignment, material deviation compensation, and process-specific tuning support repeatable alignment stability in production.

Core Alignment Engineering

01

Vision-Based Alignment

Alignment marks are checked to identify deviation between the substrate position and the reference geometry.

02

Material Deviation Compensation

Material shrinkage and deformation caused by plating, etching, and heat treatment are corrected step by step.

03

Production Condition Tuning

Equipment conditions are adjusted according to material condition and line speed to maintain stable alignment in production lines.

Alignment Engineering

Material Distortion & Alignment Correction

In Leadframe and semiconductor packaging processes, material characteristics, plating, etching, and heat treatment can cause subtle shrinkage or deformation of the material.

PRT systems use vision to check alignment marks and reference positions, focusing on reducing alignment deviation between the material and the mask.

Internal Tuning Note

PRT exposure systems are designed to compensate for material-related alignment deviation. Under defined material and process conditions, deviation in the 20–30 µm range can be corrected to the around-10 µm level or below.

These figures refer to compensated deviation on deformed production material, and are distinct from the equipment's nominal alignment accuracy specification.

Technical Confidentiality

Detailed correction structures and process recipes are configured according to customer line conditions, and specific implementation details are not disclosed in public materials.

Standard Components for Long-Term Serviceability

PRT equipment uses standard industrial components selected for long-term serviceability, replacement availability, and stable operation in production environments.
