66kW Continuous Sintering Furnace Mesh Belt Conveyor Furnace For Chip Resistors Ruthenium Paste

Precision Firing for Absolute Value Stability and High-Volume Excellence

At the core of every reliable chip resistor lies a ceramic substrate and a resistive film, whose performance is fundamentally defined during the sintering process. Tailord's Mesh Belt Sintering Furnaces are engineered to deliver the ultimate combination of thermal precision and continuous throughput, transforming alumina substrates and functional films into components that meet stringent tolerances and stability requirements. From thick-film ruthenium oxide (RuO2) based systems to high-performance thin films, our furnaces provide the controlled environment essential for achieving precise ohmic values, low TCR, and superior reliability in mass production.

Key Applications & Process Advantages for Chip Resistor Sintering:

1. Thick-Film Resistor Paste (RuO2) Firing: Achieve precise sheet resistivity and low Temperature Coefficient of Resistance (TCR) by perfectly sintering ruthenium-based pastes in air. Our multi-zone control allows fine-tuning of the profile to control the glass-ceramic microstructure, which directly defines the final resistance value.

2. Superior Alumina Substrate Handling: The smooth, continuous belt transport ensures flat, warp-free sintering of alumina ceramic substrates, which is critical for maintaining precise laser trim geometry and preventing micro-cracking in the resistive layer.

3. Exceptional Resistance Value Uniformity: With guaranteed temperature uniformity of ±3°C or better across the entire belt, we ensure every resistor on a panel, and from panel to panel, sinters identically. This is the foundation for achieving tight tolerance distributions (e.g., ±1%, ±0.1%) and high production yield.

4. Optimized TCR Performance: The TCR of a thick-film resistor is highly sensitive to the firing profile and peak temperature. Our precise and repeatable thermal control enables you to consistently hit TCR targets, from standard ±100ppm/°C to ultra-precise ±25ppm/°C grades.

5. High-Volume Manufacturing for Consumer Electronics: Engineered for 24/7 operation, our Mesh Belt Furnaces are the backbone of global chip resistor production, offering unparalleled throughput to meet the massive demand of the electronics industry while driving down cost per unit.

6. Laser Trim Stability: A well-sintered resistor film provides a stable and predictable response to laser trimming. Our process ensures minimal post-trim drift, which is crucial for achieving high accuracy in final resistance values.

7. Multi-Layer Termination Co-firing: Excellently suited for firing resistors with co-fired silver-palladium terminations. The furnace profile can be optimized to sinter both the resistive film and the termination layers simultaneously, ensuring a robust, low-resistance connection.

8. Clean Air Atmosphere for Oxide Pastes: Operating in a clean air environment is ideal for most resistor pastes, ensuring consistent oxidation states and preventing contamination that could lead to electrical noise and long-term drift.

9. Rapid Process Development for New Formulations: Accelerate the development of new resistor pastes or adapt to different substrate types. The flexible zoning allows for quick profile optimization, drastically reducing your time-to-market for new products.

10. Enhanced Long-Term Stability & Reliability: A perfectly controlled sintering process results in a stable, stress-relieved film and strong substrate bonding. This directly translates to superior performance under load life, humidity, and thermal cycling tests, meeting the stringent standards of automotive (AEC-Q200) and industrial applications.
