Process & Technology Details
High Precision Film Casting for MLCC Manufacturing
Our MLCC tape casting machine is engineered to produce ultra-thin, uniform ceramic layers with precise thickness control from 1-30μm (within 3-5% tolerance). With guide roller surface roughness ≤ Ra 0.8S and casting width accuracy ≤ ±1.5 mm, the system ensures smooth slurry spreading essential for high-density MLCC production. The ultrasonic web guiding system with swing roller correction provides exceptional film positioning accuracy, critical for consistent electrical properties in multilayer ceramic capacitors.
Advanced Heating and Drying Technology
The machine features a high-efficiency over-roll combined with suspended drying tunnel design for uniform, rapid tape drying. Six independent drying zones with PID temperature controllers and inverter-controlled airflow ensure precise thermal management. Bottom plate heating combined with hot air circulation creates uniform temperature distribution, while the modular design allows easy extension of drying chamber length to accommodate different production requirements and material formulations.
Variable Thickness Control for Diverse Applications
With precise control over film thickness ranging from 1-30μm, this tape caster supports production of various MLCC types with specific electrical properties and capacitance values. This versatility allows manufacturers to tailor ceramic tapes for different industry applications, from consumer electronics to automotive and industrial systems. The consistent thickness control is crucial for achieving reliable performance in compact, high-capacitance components.
Smooth Surface Quality and Defect Prevention
The tape casting process produces ceramic films with exceptionally smooth surfaces and minimal defects such as air bubbles, uneven texture, or irregularities. This surface quality is essential for achieving high-quality multilayer ceramic substrates that deliver optimal electrical and mechanical performance. The automated slurry spreading and tension control systems work together to eliminate common manufacturing defects that could impair component reliability.
Automated Process Control and Monitoring
Advanced automation systems control critical parameters including casting speed, slurry viscosity, and substrate tension, ensuring consistent production with minimal human intervention. Real-time monitoring systems track all process variables, providing immediate feedback and maintaining optimal operating conditions. This level of automation reduces errors, improves production efficiency, and ensures consistent quality across extended production runs.
Comprehensive Safety and Quality Assurance Systems
Japan RIKEN combustible gas detectors continuously monitor solvent concentration with automatic alarms and shutdown when limits are exceeded. Explosion-proof motors in oven zones enhance operational safety, while independent tension regulation maintains stable web tension throughout the process. Optional inline thickness measurement provides real-time 2D/3D coating maps with visual defect identification for superior quality control.
