Robust Electrode Bonding for High-Reliability MLCCs
The MLCC End-Fired Furnace is a cornerstone technology for the metallization phase of multilayer ceramic capacitor production. By providing a stable operating environment up to 950°C, the furnace ensures that end-termination pastes are fired to the perfect density. This high-temperature precision is vital for creating a robust mechanical and electrical bond between the external termination and the internal electrode layers, directly impacting the component's performance in high-frequency and automotive applications.
Advanced Atmospheric Adaptability for Diverse Pastes
To accommodate the varying chemical requirements of Nickel, Copper, and Silver-Palladium pastes, the system supports a flexible atmosphere of Nitrogen, Air, and Hydrogen. This multi-gas capability allows manufacturers to switch between oxidation and reduction processes seamlessly. The precise control of the internal environment prevents the oxidation of base metal electrodes (BME), ensuring high conductivity and preventing delamination or electrode adhesion failure during the firing cycle.
Uniform Dual-Side Heating and Structural Integrity
Thermal stress is a major cause of microcracks and warpage in ceramic chips. Our end-fired furnace utilizes a sophisticated upper and lower heating plate design that delivers perfectly balanced thermal distribution. With 15 independent temperature zones, operators can fine-tune the heating, soaking, and cooling curves to match specific product dimensions. Furthermore, the furnace liner is constructed from imported heat-resistant stainless steel, offering exceptional durability and corrosion resistance against volatile termination binders.
Scalable Production and Industrial Efficiency
Designed for high-throughput continuous sintering, the furnace offers a standard 9.5-meter chamber with optional widths of 450 mm, 650 mm, or 685 mm. This modular scalability allows factories to customize their production capacity according to demand. With a maximum heating power of 130 kW and an impressively low holding power of 70 kW, this system represents the pinnacle of energy efficiency for modern ceramic electronic component manufacturing lines.

Frequently Asked Questions
QHow does the ±3°C uniformity benefit the MLCC yield?
Uniformity ensures that every chip on the conveyor tray experiences the exact same thermal profile. This eliminates batch variations in electrode adhesion strength and prevents localized overheating, which can cause delamination.
QWhy are Hydrogen and Nitrogen atmospheres necessary?
Hydrogen and Nitrogen provide a reducing or inert environment that prevents the oxidation of base metals like Nickel and Copper. This is essential for maintaining the high conductivity required in modern MLCC electrodes.
QWhat is the advantage of using upper and lower heating plates?
Dual-side heating ensures that heat is applied evenly to both the top and bottom of the component. This reduces the vertical thermal gradient, significantly minimizing the risk of warping or thermal stress cracks in sensitive ceramic layers.
QIs the stainless steel liner resistant to chemical outgassing?
Yes. The imported heat-resistant stainless steel is specifically chosen for its ability to withstand the corrosive outgassing of organic binders and solvents typically found in termination pastes during the initial firing stages.
QWhat chamber dimensions are available for this furnace?
The furnace features a standard chamber size of 9500 × 50 mm, with options for customized widths of 450 mm, 650 mm, or 685 mm to align with different factory throughput and capacity requirements.
QWhat is the power consumption profile of the furnace?
The system is engineered for high energy efficiency, operating with a maximum heating power of 130 kW and requiring a stable holding power of only 70 kW during continuous production phases.
