LOCTITE ECCOBOND FP4322 is a high purity liquid epoxy encapsulant designed for semiconductor encapsulation. It is a high flow material which requires a cavity of flow control barrier to prevent excessive flow. LOCTITE ECCOBOND FP4322 is suitable for encapsulating bare chips mounted to plastic substrates as well as potting of small hybrid circuit modules. Spot encapsulation of bare chips on ceramic substrates is not suggested in most cases.
