RMA Rosin Core Solder Wire
RMA Rosin Core Solder Wire is the manufacturers’ choice for mildly activated, general-purpose rosin solder wire, ideal for military and aerospace applications. RMA rosin flux provides fast wetting and excellent tarnish/oxide removal, producing bright and shiny joints.
RMA post-process residues may remain in place after soldering. High reliability assemblies may be cleaned using commercially available flux removers.
RMA is available in lead-free and leaded alloys.
