Precision Blanking for Multilayer Ceramic Substrates
The Tape Blanker (Green Sheet Slitter) is a critical piece of equipment in the fabrication of LTCC (Low Temperature Co-fired Ceramic) and HTCC (High Temperature Co-fired Ceramic) components. After the tape casting process, ceramic green sheets must be precisely cut into individual blanks before via punching and circuit printing. Our slitter utilizes a high-precision servo-driven mechanism to achieve a cutting accuracy of ±0.3 mm, ensuring that the dimensional integrity of each layer is maintained for perfect registration in multilayer stacks.
Flexible Configuration for Prototype and Mass Production
Adaptability is key in modern electronic ceramic manufacturing. This system supports multiple green tape widths—primarily 152.4 mm (6 inches) and 203.2 mm (8 inches)—to suit various substrate design requirements. With an adjustable cutting length ranging from 100 mm to over 200 mm, manufacturers can easily switch between different product formats. Whether you are producing small batches of specialized sensors or high-volume substrates for 5G modules, our blanker provides the scalability needed for your production line.
Advanced Material Handling and Carrier Film Stability
Working with sensitive ceramic materials requires delicate handling to prevent deformation or surface damage. Our slitter is specifically engineered to handle green tapes ranging from 0.1 mm to 0.5 mm in thickness, supported by PET carrier films. The optimized mechanical design ensures stable tension control and a clean release from the carrier film, minimizing edge burrs and material waste. This precision is vital for maintaining high yield rates in high-density interconnect (HDI) ceramic applications.
Automated Workflow for Enhanced Industrial Efficiency
Efficiency meets intelligence with our automated control system. Featuring a user-friendly touchscreen interface and a high-speed cutting cycle of 3 to 8 seconds per piece, the machine significantly reduces labor dependency. The system supports both 3-inch and 6-inch roll inner diameters and handles large outer diameter rolls up to 350 mm, allowing for extended periods of continuous operation with minimal downtime for roll changeovers. This makes it an ideal choice for smart factories aiming for high-throughput LTCC/HTCC manufacturing.

Frequently Asked Questions
In multilayer ceramic processes, each layer must align perfectly with the others during the lamination stage. If the blanking dimensions vary, the internal circuit patterns and vias will not align, leading to electrical failure and poor yield.
Yes. The system is designed to be compatible with standard 3-inch and 6-inch inner diameter rolls. The maximum outer diameter supported is 350 mm, providing long-run continuous production capability.
The system uses specialized tension control and smooth rollers to ensure the green tape does not stretch or crack. It is optimized for tapes on PET carrier films, ensuring a clean cut without sticking or deforming the delicate ceramic material.
The 3-8 second adjustable cycle allows operators to synchronize the blanking speed with the material's properties. Thicker or more fragile ceramic formulations may require a slower cycle for a cleaner edge, while standard materials can be processed at maximum speed.
The system is highly versatile and optimized to process ceramic green tapes ranging from 0.1 mm to 0.5 mm in thickness, supported by PET carrier films with a thickness of 0.05 mm to 0.1 mm.
This system supports both 3-inch and 6-inch inner diameter rolls and is designed to handle larger roll outer diameters up to 350 mm, minimizing downtime during roll changeovers.
