Precision Registration and Multilayer Stability
The MLCC Roll-to-Roll Printer is engineered for ultra-precise alignment, featuring a platform lifting repeatability of ±5 μm. This exceptional stability ensures that multilayer ceramic substrates are printed with perfect registration, which is essential for the reliability of high-density electronic components in the automotive and telecommunications sectors.
Versatile Printing for Diverse MLCC Scales
Supporting ceramic green tape thicknesses from 1.3μm to 30μm, this system is highly adaptable to various production needs, ranging from 0201 to 1206 MLCC sizes. The continuously adjustable squeegee speed (100–750 mm/sec) allows for fine-tuned control over different slurry viscosities, ensuring crisp and accurate pattern definition on every layer.
Advanced Thermal Curing and Drying Uniformity
Equipped with a 6-meter drying zone, the system utilizes a combination of hot air and infrared (IR) heating. With temperature control accuracy of ±1°C and furnace uniformity of ±2°C, it provides a stable environment for even solvent evaporation. This meticulous thermal management prevents film warping and guarantees consistent quality across the entire roll.
Intelligent Slurry Management and Automation
An integrated PLC-controlled automatic slurry feeding system monitors paste weight in real-time via high-precision sensors. By maintaining a steady slurry flow and constant viscosity, the machine minimizes material waste and reduces the need for manual intervention, making it an ideal choice for fully automated MLCC production lines.
Integrated Vision Inspection for Yield Optimization
To ensure zero-defect production, the printer features a high-resolution vision inspection system. Pre-print cameras detect film pinholes and surface defects, while post-print inspection monitors alignment quality through MARK points. This real-time feedback loop allows the system to automatically eject defective sections, significantly enhancing overall process reliability and yield rates.

Frequently Asked Questions
What printing accuracy does this machine provide?
The system features a platform lifting repeatability of ±5 μm and advanced CCD alignment, ensuring sub-micron precision for multilayer registration in complex ceramic circuits.
How does the pinhole inspection system work?
The pre-print high-precision camera scans the full width of the ceramic green tape. If a pinhole or defect is detected, the PLC automatically pauses printing and ejects the defective segment to prevent yield loss.
What is the benefit of the hot air + infrared drying system?
This hybrid method provides rapid yet uniform heating. IR penetrates deep into the slurry layers while hot air removes surface solvents, preventing "skinning" and ensuring a defect-free finish across the 6-meter zone.
Can the slurry feeding system handle different viscosities?
Yes. The squeegee speed and printing stroke are continuously adjustable, and the automatic feeding system features a low-speed grinding function (up to 100 rpm) to keep various paste types at the optimal consistency.

Main Mechanisms
| Main Mechanisms | Description | Photo |
|---|---|---|
| Unwinding & Rewinding Unit | Ultrasonic edge sensors detect the position of the transparent PET film edges, enabling the unwinding and rewinding shafts to intelligently align the film. This ensures consistent positional accuracy, precise edge alignment, and smooth, deformation-free film transport. | |
| Printing Unit | The printing table adopts a lifting mechanism, allowing the distance between the screen and the platform to be adjusted for easy cleaning. The squeegee head is mechanically fixed and can be set to automatically stop the machine after printing 5–100 sheets. | |
| Drying Unit | Utilizes hot air and infrared heating, with a temperature range from room temperature up to 100°C. The temperature variation within the oven is controlled within ±2°C to ensure uniform drying of the film. There are three temperature zones, each equipped with a direct exhaust fan and two differential pressure gauges to monitor the pressure difference between the oven and the external environment in real time. The intake blower filter is also equipped with a pressure gauge to monitor clogging status. | |
| Pinhole Inspection Function | Equipped with defective film detection before and after printing. A full-width pinhole inspection is conducted before printing, and the results are displayed in real time on the touchscreen, showing NG/OK status. If a defect is detected, the machine will automatically stop printing and eject the defective film. Printing will automatically resume after the defective section is removed. | |
| MARK Point Detection Function | Two CCD cameras are installed after printing to inspect the quality of the print step alignment via MARK points. If a MARK point defect is detected or after screen cleaning (adjustable to inspect the first 1–5 sheets), the system can automatically process and remove defective MARK prints using a dedicated MARK removal mechanism. |  |
| Automatic Slurry Feeding System | Equipped with a weighing sensor to monitor the internal slurry weight in real time. When the weight drops below the preset value, the system triggers an alarm. In combination with detection sensors, it automatically feeds printing slurry to the printing zone to prevent insufficient supply. The slurry spreading plate can be set for continuous or interval-based operation and features a low-speed grinding function, with adjustable rotation speed up to 100 rpm. | |
| Electrical System | The system uses PLC control, ensuring stable and reliable performance. A touchscreen interface provides user-friendly, menu-based operation. |
