RMA Cored Wire
RMA is a mildly activated, general-purpose wire solder for use in applications requiring good activation. RMA cored wire is active enough for excellent tarnish or oxide removal, and will produce bright shiny solder joints. RMA wire will leave slight to moderate post-process residues that may be left on noncritical applications, but should be removed from any critical applications. RMA cored wire meets Mil-Spec cleanliness requirements without cleaning. IPC flux classification for this material is ROL0.
