Solder spool POS-61 without rosin (d3.0mm 100g) Rexant 09-3124

POS-61 solder is intended for soldering and tinning parts of electrical and radio equipment, precision instruments, printed circuit boards, and medical equipment. It is particularly effective when working with components sensitive to overheating. It is a wire (3.0 mm in diameter) made of an alloy of tin (60%) and lead (40%). How the solder works: when heated to a certain temperature (183...190 °C), it melts, wets the metal being soldered, spreads over it, and fills the space between the connected parts. POS-61 solder possesses properties such as corrosion resistance, creation of mechanical strength of the soldered joint, and specific conductivity (for current-carrying elements). Main characteristics: Solder diameter: 3.0 mm Composition: tin (60%) and lead (40%) Shelf life: indefinite.
