Sn63/Pb37 No Clean Solder Paste 4860P Technical Data Sheet 4860P Description The MG 4860P No Clean Solder Paste is a no clean solder paste designed for surface mount applications using a syringe dispensing method. The post soldering residues of 4860P are non-conductive, non- corrosive and highly insulated. Benefits Low residues Easily dispensed Excellent wettability Hard non-conductive residues Solder Composition of MG 4860P Solder Paste Sn63 alloy is the conventional eutectic solder used in most electronic assemblies. The Sn63 alloy conforms and exceeds the impurity requirements of J-STD-006 and all other relevant international standards.

Solder powder distribution is measured utilizing laser diffraction, optical analysis and sieve analysis. Careful control of solder powder manufacturing processes ensures the particles shape are 95% spherical minimum (aspect ratio < 1.5) and that the alloy contains a typical maximum oxide level of 80 ppm.
