Multilayer ceramic capacitors (MLCCs) are indispensable components in modern electronic systems, providing critical functions such as energy storage, signal filtering, decoupling, and noise suppression across a wide range of consumer, industrial, and automotive applications. As MLCC structures continue to evolve toward smaller sizes, higher capacitance, and greater reliability, the performance of electrode pastes plays an increasingly vital role in ensuring the electrical, mechanical, and environmental stability of these devices. High-quality electrode pastes ensure precise layer formation, strong ceramic adhesion, stable electrical conductivity, and long-term reliability under demanding operating conditions, ultimately supporting the continued innovation and scaling of next-generation MLCC devices.
MLCC electrode pastes must meet a unique set of technical demands to ensure reliable device fabrication and performance. First, the paste needs well-controlled viscosity and exceptional dispersion stability to achieve smooth and defect-free printing through screen or gravure processes. Second, sintering performance is critical; the resulting metal layer must reach high density and conductivity, forming a strong bond with the ceramic substrate to withstand subsequent electroplating and high-temperature reflow processes. Additionally, the paste should maintain minimal impurity levels, support compatibility with multilayer lamination and co-firing procedures, and ensure long-term reliability under mechanical stress, humidity, and thermal cycling.
Our company provides a comprehensive portfolio of high-performance MLCC electrode pastes tailored to meet the diverse needs of the industry.
Designed specifically for screen-printed internal electrodes, this nickel paste offers stable viscosity, smooth paste flow, and excellent print definition. After sintering, it forms a dense, uniform, and highly conductive nickel layer with strong adhesion to the ceramic substrate, ensuring reliable electrical performance and compatibility with multilayer lamination processes.
Engineered for precision gravure printing processes, this nickel paste features optimized rheology and exceptional dispersion stability to ensure smooth ink transfer and highly uniform coating. It supports ultra-fine pattern resolution, consistent film thickness, and excellent surface flatness, making it ideal for producing thin, stable, and reliable internal electrodes in advanced high-capacitance MLCC designs.
Formulated for high-reliability end terminations, this copper-based paste delivers excellent conductivity, strong adhesion, and high sintering density. After firing, it forms a dense and robust copper layer that effectively prevents the infiltration of plating solutions during subsequent electroplating. Additionally, it offers strong environmental stability and full compliance with RoHS directives.
Designed for flexible MLCC terminations, this epoxy-silver paste combines high conductivity with outstanding mechanical durability. The cured silver layer exhibits strong bending resistance, excellent adhesion, and stable curing behavior, effectively preventing cracking, delamination, or performance degradation during device handling, flexing, or assembly.
