Lead Free No Clean Solder Paste by MG Chemicals
Part No.: 4900P-250G
The 4900P No Clean Solder Paste is made from a blend of high-purity, non-recycled tin, silver, and copper metal powder mixed with a no clean flux. This lead-free and halogen-free solder paste is designed for extreme flux activity and enhanced printing characteristics needed for ultra-fine pitch applications. It provides excellent wetting on copper OSP-coatings. Wide reflow process windows combined with high thermal stability yield solder joints with smooth surfaces.
Applications & Usages
The solder paste is designed to accommodate high speed printing. It can yield brick-like prints even when using an ultra-fine pitch stencils down to 0.3 mm.
