Application Scenarios

Pre-AOI Cleaning to Reduce False Rejects

Automated optical inspection (AOI) systems cannot distinguish between a genuine surface defect and a loose particle resting on the substrate surface. In high-throughput lines, this causes false rejection rates that increase rework costs and reduce effective yield. Positioning the STXT Series inspection cleaner immediately before the AOI station removes transient surface particles, so the AOI system only flags genuine defects.

Pre-Bonding Inspection Stage Cleaning

Before ACF bonding or lamination in display manufacturing, the substrate must pass both a cleanliness check and a surface condition inspection. The STXT Series integrates cleaning with inspection readiness, ensuring the substrate arrives at the inspection camera or operator station in the cleanest possible state for accurate assessment.

Inline Quality Gate for Display Panel Lines

In display panel production, the inspection stage is the final quality gate before components are committed to assembly. Surface particles that pass through inspection become permanent defects in the finished display. The STXT Series acts as an inline contamination barrier, giving inspection equipment the best possible surface condition to work with.

The Cost of Skipping Pre-Inspection Cleaning

Without a cleaning step before inspection, AOI false rejection rates typically run 3–8% in display and electronics manufacturing environments. At high production volumes, this translates directly into wasted rework hours on panels that have no genuine defects. More seriously, particles that are missed and passed through inspection become permanent assembly defects. The STXT Series pre-inspection cleaner addresses both problems — reducing false rejects and preventing genuine contamination from reaching final assembly.

Frequently Asked Questions

Why is cleaning needed before optical inspection?

Automated optical inspection systems detect surface anomalies — they cannot distinguish a genuine defect from a loose dust particle. Without pre-inspection cleaning, transient particles cause false rejections that increase rework costs and waste production capacity. Cleaning immediately before inspection ensures the AOI only flags genuine defects.

What does the anti-static RPP0 grade DK system do?

The RPP0 grade DK anti-static system provides high-performance static charge neutralization on the substrate surface before inspection. Substrates carrying electrostatic charge actively attract airborne dust after cleaning. Neutralizing the charge immediately before inspection prevents re-contamination during the transit from the cleaner to the inspection camera.

Can the STXT Series be installed directly before an existing AOI machine?

Yes. The STXT Series is designed for inline installation immediately upstream of inspection equipment. It can be configured to match the conveyor speed, board width, and transport height of your existing inspection line. Contact us with your AOI machine model and line specifications.

How does the machine handle substrates of different thicknesses?

The adhesive roller and transport system are adjustable to accommodate substrates of varying thickness. Specific thickness ranges are confirmed during the application specification review before order.

Does the inspection cleaner also remove static charge?

Yes. The integrated anti-static system neutralizes electrostatic charge on the substrate surface as part of the cleaning process, preventing re-attraction of particles immediately after the cleaning pass.

What industries use the STXT Series inspection cleaner?

The STXT Series is used in LCD and OLED display manufacturing, FPC assembly, PCB fabrication, optical film production, and any electronics manufacturing process where pre-inspection surface cleanliness directly impacts yield and inspection accuracy.
