Product Description
LOCTITE® ECCOBOND FP4549 liquid epoxy adhesive is designed forenhanced adhesion to integrated circuit passivation materials. LOCTITE® ECCOBOND FP4549 material is formulated to quickly underfill devices at 90°C to 110°C with as little as a 1/2 mil gap.
When fully cured, the material forms a rigid, low stress seal that dissipates stress on solder joints and extends thermal cycling performance.
