4900P - SAC305 Solder Paste - No Clean

4900P SAC305 Solder Paste is a no clean solder paste made from a blend of high-purity, non-recycled tin, silver and copper metal powder mixed with a no-clean flux. This halogen-free and lead-free solder paste is designed for extreme flux activity and the enhanced printing requirements of 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.

4900P is the best lead-free solder paste for facilitating high speed printing. It can yield brick-like prints even when using ultra-fine pitch stencils as small as 0.3 mm.

We also offer a no clean Sn63/Pb37 solder paste and a no clean low temperature solder paste.
