Ceramic Disc Cleaning-Waxing Integrated Machine Automated Semiconductor Industries

Product Overview

This ceramic disc cleaning & waxing integrated machine combines one ceramic disc cleaner with dual ceramic disc mounters, designed for high-efficiency cleaning and wafer waxing in sapphire and semiconductor industries, achieving stable 99.9% yield rate.

Technical Specifications

Working Principle

Ceramic Disc Cleaning Stage

• Precision Cleaning: Utilizes ultrasonic cleaning with deionized water (≥12MΩ·cm) to remove micron-level contaminants from ceramic discs.

• Drying System: High-efficiency air knives and vacuum drying ensure zero residual moisture.

Automated Waxing Process

• Vision Alignment: CCD cameras scan disc surface coordinates, achieving ±0.02mm positioning accuracy.

• Controlled Wax Deposition: Programmable wax dispensing heads apply 0.8g±0.05g wax per wafer.

• Pressure Optimization: Pneumatic actuators maintain 5-10N/cm² uniform contact pressure during wafer mounting.

Integrated Control

• Synchronized Operation: PLC coordinates cleaning module and dual waxing stations, enabling parallel processing (Max. 30 discs/hour).

• Quality Feedback: Real-time thickness sensors detect wax layer uniformity, automatically adjusting parameters if deviations exceed ±3%.

Key Advantages

• Energy Efficiency: Pure water recycling rate >80%, wax consumption 0.8g/wafer, 35% lower energy per disc

• Smart Connectivity: Compatible with MES/ERP for full-process data traceability (thickness/pressure/time)

• Scalability: Customizable tooling and recipes for Φ300-650mm non-standard discs

Production Capacity

Applications

Full-process ceramic disc treatment: Cleaning→Drying→Waxing in one machine
