92-XCON OA flux is formulated for Pb-free soldering, and designed to withstand the high temperatures associated with Pb-free processing without breaking down or losing its activity. Said to offer a robust process window and combine freely rinsable, thermally stable synthetic polymers with a well-tuned activator system. Delivers metallurgically sound solder joints with a shiny appearance even under high thermal load. Cleans easily in a straight aqueous process, yielding circuit assemblies with extreme ionic cleanliness. Passes the Silver Chromate test for halides and is categorized as an IPC-Jstd-004 ORH0 product. Cobar BV, cobar.com
