Core Technical Highlights
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
Q: What printing accuracy does this machine provide?
A: 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.
Q: How does the pinhole inspection system work?
A: 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.
Q: What is the benefit of the hot air + infrared drying system?
A: 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.
Q: Can the slurry feeding system handle different viscosities?
A: 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.
Q: What range of green tape thickness and MLCC sizes does this printer support?
A: It supports ceramic green tape thicknesses ranging from 1.3μm to 30μm. This versatility makes it highly compatible with various production needs, spanning MLCC sizes from 0201 to 1206.
Q: What is the maximum printing area capability of the machine?
A: The printer supports a maximum printing area of 340mm × 340mm, designed to accommodate high-density substrate configurations with optimized throughput.
