POWEREACH JC2000X1 Advanced Large-Platform Contact Angle Analyzer for LCD Panel Cleanliness Assessment

Overview

The POWEREACH JC2000X1 is a benchtop dynamic contact angle analyzer engineered for high-precision surface wettability characterization of large-area flat substrates—particularly suited for in-line quality assurance of liquid crystal display (LCD) panels, photovoltaic glass, touch sensors, and other optoelectronic components requiring non-destructive, whole-panel cleanliness assessment. Unlike conventional goniometers with limited stage dimensions, the JC2000X1 integrates a rigid 400 × 400 mm aerospace-grade aluminum sample platform, enabling edge-to-edge measurement of oversized rigid or semi-rigid specimens without sectioning. Its core measurement principle relies on high-resolution side-view silhouette imaging of sessile or pendant droplets, followed by pixel-based contour extraction and Young–Laplace fitting algorithms to determine static, advancing, and receding contact angles. The system supports both manual and automated dispensing via integrated peristaltic pump modules (optional), facilitating dynamic contact angle hysteresis analysis in compliance with ASTM D7334 and ISO 19403-2 standards.

Key Features

• Rigid 400 × 400 mm precision-machined aluminum stage with flatness tolerance ≤ ±5 µm over full area—optimized for dimensional stability under thermal and mechanical load.
• Adjustable optical path with motorized zoom lens (0.7×–5×) and variable pixel density (50–318 px/mm), ensuring sub-pixel droplet boundary resolution across diverse sample heights (working distance: 120–300 mm).
• Dual-mode contact angle quantification: tangent (θ_t) and height (θ_h) methods, plus advanced image-analysis-based automatic contour detection with real-time edge refinement.
• Integrated high-speed frame capture (up to 200 fps) synchronized with dispensing triggers—enabling transient wetting dynamics recording during droplet deposition and retraction.
• Surface energy calculation module supporting Owens–Wendt, Wu, van Oss–Chaudhury–Good, and Fowkes models using two-liquid or three-liquid protocols (e.g., water, diiodomethane, ethylene glycol).
• Modular architecture compatible with optional upgrades: motorized XYZ translation stage, auto-dosing syringe pump, environmental chamber (±5–85°C, RH 10–90%), and vacuum desiccation module.

Sample Compatibility & Compliance

The JC2000X1 accommodates rigid planar samples up to 400 × 400 × 50 mm (L × W × H), including tempered glass, ITO-coated substrates, polymer films, printed circuit boards, and ceramic wafers. Its open-stage design permits direct placement of finished LCD modules—eliminating the need for destructive sampling or edge trimming. All firmware and software comply with GLP documentation requirements, including electronic audit trails, user access control (three-tier permission levels), and data integrity safeguards aligned with FDA 21 CFR Part 11 Annex 11 principles. Measurement repeatability meets ISO 19403-4 specifications (< ±0.3° RSD for triplicate measurements on homogeneous surfaces), and surface tension calibration traceability is maintained via certified reference liquids (e.g., Milli-Q water, n-hexadecane, formamide).

Software & Data Management

POWEREACH’s proprietary DROPimage Advanced v5.2 software provides unified control of hardware, image acquisition, and quantitative analysis. Key capabilities include: time-lapse sequential capture with programmable intervals (10 ms–60 s); batch processing of multi-point datasets with georeferenced coordinate mapping; export of raw TIFF sequences and processed CSV/Excel reports with metadata (timestamp, operator ID, instrument serial, calibration log). Database functionality supports relational tagging by project, sample ID, lot number, and test protocol—enabling retrospective trend analysis and CAPA linkage. Software updates are delivered free-of-charge for life, with version-controlled release notes and validation documentation available upon request for regulated environments.

Applications

• Final QA of LCD/OLED panel surface cleanliness: detecting residual organic contaminants, cleaning agent residues, or plasma treatment uniformity via contact angle mapping across panel edges.
• Adhesion prediction for optical bonding, AR/AF coating, and conductive ink printing—correlating surface energy components with interfacial fracture toughness.
• Development and validation of anti-fingerprint, oleophobic, and hydrophobic nanocoatings on cover glass and touch modules.
• Process monitoring of wet chemical etching, spin coating, and inkjet deposition in semiconductor and display manufacturing lines.
• Research on low-surface-energy materials (e.g., fluoropolymers, siloxanes) and hierarchical micro/nanostructured surfaces for self-cleaning applications.

FAQ

Is the JC2000X1 suitable for measuring curved or irregularly shaped samples?
No—the JC2000X1 is optimized for flat, rigid substrates. For cylindrical or spherical geometries (e.g., insulators, fibers), refer to the JC2000X6 or JC2000X6E series with dual-axis rotational stages.
Does the system support automated multi-point scanning across the full 400 × 400 mm stage?
The base JC2000X1 model supports single-position measurement. Motorized XY translation and auto-positioning are available as factory-installed options (JC2000X3 or JC2000X6E configurations).
What calibration standards are included with shipment?
Each unit ships with NIST-traceable contact angle calibration slides (10°, 60°, 110°), certified surface tension reference liquids (water, diiodomethane), and a full calibration certificate valid for 12 months.
Can the software generate GMP-compliant reports with electronic signatures?
Yes—DROPimage Advanced supports 21 CFR Part 11-compliant electronic signatures, audit trail review, and report locking mechanisms when configured with domain-authenticated user accounts.
Is technical support available outside mainland China?
POWEREACH maintains authorized service partners in Germany, Japan, South Korea, and Singapore; remote diagnostics and English-language application engineering support are provided globally.
