LOCTITE\u00ae 3512\u2122 is a single component, epoxy adhesive
\ndesigned for use as an underfill for CSP (FBGA) or BGA. It
\ncures rapidly on exposure to heat. It is designed to give
\nexcellent protection of printed circuit boards from soldering
\nfailure due to impact and thermal cycling. The low viscosity
\nallows filling in gaps under CSP or BGA.
