This precision is critical for round holes ranging from φ0.08 mm to φ5 mm and square holes up to 4.2×4.2 mm, ensuring proper alignment for subsequent via-filling and layer stacking processes in advanced multilayer ceramic manufacturing.

Wide Processing Range and Material Compatibility

Designed for versatility, this punching machine supports both 6-inch and 8-inch ceramic green sheets with thicknesses up to 0.5 mm. It accommodates both PET-supported and PET-less green tapes, providing manufacturers with greater flexibility for R&D prototyping and production scale-up. This compatibility with various material formats allows seamless integration into existing LTCC production lines without requiring extensive process modifications.

Fully Automated Workflow for Enhanced Efficiency

The integrated automatic sheet loading/unloading system and efficient waste collection mechanism significantly reduce manual handling and contamination risks. By minimizing operator intervention, this automated approach improves production efficiency, ensures operator safety, and maintains consistent yield rates throughout extended production runs. The streamlined workflow also reduces setup time between different product configurations.

Intelligent Control System with Modular Flexibility

Our proprietary PLC control system features an intuitive user interface for easy parameter setting and real-time process monitoring. The modular punching head configuration (4 high-speed + 4 low-speed units) allows quick adjustment for various via designs and patterns, enabling rapid changeovers between different product specifications. This flexibility is particularly valuable for manufacturers producing diverse ceramic components with varying via requirements.

Robust Construction and CE-Certified Safety

Built with a heavy-duty carbon steel frame, the machine maintains exceptional stability during high-speed punching operations. CE-certified safety design ensures compliance with European industrial standards, featuring comprehensive safety covers, emergency stop systems, and interlock mechanisms. This robust construction not only enhances operational safety but also extends equipment lifespan in demanding production environments.

LTCC Via Punching Applications

Frequently Asked Questions

What is a ceramic green sheet punching machine used for?

A ceramic green sheet punching machine creates micro vias and cavities in unfired LTCC/HTCC ceramic sheets for multilayer circuit interconnections. These holes are later filled with conductive paste to create vertical connections between circuit layers in multilayer ceramic components.

What hole sizes can this punching machine achieve?

This machine can create round holes from φ0.08 mm to φ5 mm and square holes up to 4.2×4.2 mm. The ±10 µm positioning accuracy ensures consistent hole quality even at the smallest diameters, which is critical for high-density interconnects in advanced RF circuits.

How does the vision alignment system work?

The system uses high-resolution CCD cameras to identify fiducial marks on green sheets, then precisely aligns the punching heads before each operation. This visual alignment combined with mechanical positioning ensures ±10 µm accuracy across the entire punching area.

What materials can this machine process?

The machine processes both PET-supported and PET-less LTCC green sheets up to 0.5 mm thick in 6-inch and 8-inch formats. It accommodates various ceramic formulations used in LTCC/HTCC manufacturing, with adjustable parameters for different material characteristics.

How does the automatic waste collection system work?

The integrated waste collection system captures punched-out ceramic material through vacuum extraction, preventing debris accumulation and contamination. This automated process maintains clean working conditions and reduces manual cleaning intervals during production.

Can this machine be integrated with other LTCC production equipment?

Yes, this punching machine is designed for seamless integration with upstream printing systems and downstream stacking equipment. Standard material handling interfaces and communication protocols allow it to function as part of a complete LTCC production line.
