?Product Name:Rosin Flux Core Solder ?Brand:MASSMALL ?Alloy:Tin 63% Lead 37% ?Flux:2% ?Melting Point:361F/183C ?Wire Dia:0.3mm(0.0119inches) ?Gross Weight:65g/0.143lbs ?Reel Size:55mm x 28mm/2.165inch x 1.1 inch ?Package Content:1 x 0.3mm 65g Sn63/Pb37 Solder Wire Spool ?Features:Perfect combination of tin and lead,Lower melting point,more smoothly soldering,much shining soldering point. ?Good wettability,conductivity,thermal conductivity and easy to be tin-plated. ?Evenly distributed flux,and no broken flux in the core solder. ?Uniform winding without knot.Quick tin-plated speed and very little residue. ?Applications:Computer,precision instrument,communication instrumentation,electronics,micro-technology and other fields with high requirement for welding. ?Welding precautions: ?1.The soldering tin should not be too much,soaking the terminal is enough.It is better to complete the welding of each solder joint for only once welding,and if repair welding is required,the iron head can only be removed after the soldering tin used by the twice welding melt together.If the solder joint is not smooth,repair welding with added soldering tin can be carried out until satisfied. ?2.The weldment cannot be moved during the cooling process of the soldering tin,otherwise false welding may be caused.
