AIM RMA258-15R is a rosin based solder paste that has been developed to offer long pause-to-print capabilities while enhancing fine print definitions. RMA258-15R reduces such defects as voiding and eliminates head-in-pillow. The superior wetting ability of RMA258-15R results in bright, smooth and shiny solder joints. RMA258-15R is capable of exceptional reflow during long, hot profiles. RMA258-15R leaves medium, amber colored post process residues.
