Silver-Palladium Paste is applied to the internal electrode printing of MLCC products. A grayish-black, paste-like fluid primarily consisting of palladium silver powder, organic resin, and organic solvent. It features good dispersion without agglomeration; excellent printing characteristics without erosion to the dielectric layer; strong adhesion that effectively solves the cracking problem caused by the paste; and a flat and continuous metal layer after sintering. It does not contain harmful substances such as Pb, Cd, etc. (meets RoHS 2.0 requirements), and can be customized with different silver-palladium ratios based on customer needs.

It is a low-temperature curing silver paste product used for external electrodes of MLCC (0402 size and above) soft terminals. This product has a complete paste morphology in dipping process, no defects, and the soft end electrode is firmly attached to the end electrode without easy detachment. It has good conductivity, strong bending resistance, and strong reliability.
The red paste like fluid is mainly composed of copper powder, glass powder, and organic binder. It does not contain prohibited substances such as lead, pot, or hexavalent chromium, and meets the environmental requirements of the ROHS directive. Usually be used in MLCC as an end electrode. This product has excellent performance, with a complete and defect free paste morphology in dipping process. After sintering, it can form a dense copper layer, preventing the invasion of Ni plating solution during electroplating; At the same time, this product can minimize the occurrence of pinholes at the end, thereby improving the reliability of MLCC products
This series of products is applicable to the production of MLCC products. Gray black paste like fluid, mainly composed of nickel powder, organic resin, and organic solvent. Nano-sized nickel powder is easy to agglomerate, the internal electrode may appear electrode discontinuity and unevenness after sintering, therefore this nickel paste with good dispersion and stability has been developed. It shows good adhesion with the dielectric layer after stacking and good electrode continuity and flatness after sintering, greatly improves the reliability and compressive strength of MLCC. The shrinkage matching, crack, yield and reliability can be improved by adjusting the additives.
This silver paste product designed for application to the external electrodes of MLCCs terminals. Silver gray paste like fluid, mainly composed of silver powder, glass powder, and organic binder.Does not contain prohibited substances such as lead, cadmium, hexavalent chromium, etc., meets the environmental requirements of RoHS directive, and is applied to Class I and II capacitors.
