MLCC Copper Terminal Paste

Multilayer ceramic capacitor (MLCC) copper terminal paste is a specialized conductive material formulated for forming external terminals on multilayer ceramic capacitors. Using highly refined copper powder combined with optimized organic vehicles, dispersants, and binders, this paste provides stable rheology, smooth dipping behavior, and uniform coating coverage. Its environmentally compliant composition excludes hazardous substances such as lead, cadmium, and hexavalent chromium, fully aligning with ROHS requirements. During firing, the paste sinters into a compact, well-bonded copper layer that effectively resists penetration by subsequent electroplating solutions, safeguarding terminal integrity. By reducing end-face defects and suppressing pinhole formation, this copper terminal paste enhances mechanical stability, electrical performance, and long-term reliability of MLCC components.
