- Description
- Technical specification
LOCTITE® ECCOBOND FP4526 is a heat-curable 63%-filled underfill designed for capillary flow on flip chip applications. Its fast flow and low viscosity, along with its excellent wettability and adhesion, make it ideal for high-reliability applications. It can be used on ceramic, organic, solder mask and polyimide substrates, but is perfect for ceramic packages and FC on flex applications.
