ALPHA RF-800 provides the broadest process window for a no-clean flux with less than 5% solids content.ALPHA RF-800 is designed to provide excellent soldering results (low defects rates), even when the surfacesto be soldered (component leads and pads) are not highly solderable. RF800 works particularly well with barecopper boards protected with organic or rosin/resin coatings and with tin-lead coated PCB's. ALPHA RF-800is used successfully in both tin-lead and lead-free applications.GENERAL DESCRIPTIONALPHA RF-800 is a very active, low solids, no-clean flux. It is formulated with a proprietary activator system. A smallpercentage of rosin is added for enhanced thermal stability. The activators are designed to provide the broadestoperating window for a low solids, no-clean flux, while maintaining a high level of long-term electrical reliability. Afterwave soldering, ALPHA RF-800 leaves a low level of non-tacky residue, which is easily penetrable in pin testing.
