The 4860P Sn63/Pb37 No Clean Solder Paste is made from a blend of high purity, non-recycled tin and lead alloy powder blended with a no clean flux to form a paste. It is designed for surface mount applications and provides high tack force and good wettability. The post soldering residues are transparent, nonconductive, non-corrosive, and highly insulated. No clean means that residues are not harmful to assemblies.

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.
