Solder Wire 0.8mm 100g - 63/37 Tin-Lead Rosin Core a3967 8I/Os interface: easily connects toA 100g spool of 0. 8mm tin lead solder with a rosin flux core. The 63 37 alloy is eutectic: it goes from solid to liquid at 183C with no mushy in between stage, which means fewer cold joints than 60 40. Specs Alloy 63 37 tin lead Diameter 0. 8mm Weight 100g Core Rosin flux Flux content 1. 8 2. 2% Melting point 183C 0. 8mm is the all rounder size: fine enough for headers and pads, thick enough for wires and connectors.
