LOCTITE® ECCOBOND FP4802

Known as FP4802 30CC SEMCO 50.4G -40CD

Features and Benefits

A 1-part, black, high-purity encapsulant designed for applications utilizing lead-free solder. It's suitable for protecting bare chips in a variety of advanced packages.
LOCTITE® ECCOBOND FP4802 is a black, high-purity liquid encapsulant specially designed for use in applications utilizing lead-free solder. It was formulated to meet the non-halide objectives of many technical users and for temperature cycling ranges up to-65 to 150°C (-40°F to 302°F). It features excellent flow properties, allowing the material to penetrate fine pitch wires and deep cavities without entrapping voids. A cavity or potting dam is required for flow control. It is ideal for bare chip protection of a variety of advanced packages, such as Ball Grid Arrays (BGAs), Chip Scale Packages (CSPs), Plastic Ball Grid Arrays (PBGAs), and full arrays on Low Temperature cofired Ceramic (LTCC).
