Information

LOCTITE® 3568 is an epoxy-based liquid underfill compatible with polyimide and silicon nitride passivated flip-chip, CSP, BGA and µBGA assemblies. It cures in 5 to 15 minutes when exposed to temperatures of 150°C to 165°C (302°F to 329°F), is easy to dispense, and quickly penetrates gaps as small as 0.025 mm (0.001”). It's designed to provide processing and reliability similar to conventional thermoset underfills but with the added advantage of reworkability: when heated to high temperatures for short periods of time (typically 210°C/410°F to 220°C/428°F for 1 minute) the cured epoxy matrix undergoes physical and chemical transformations, allowing removal of the component when torque is applied.
