功能與優點
This black, high-purity encapsulant is 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 coating liquid for encapsulating lead-free solder applications. It’s suitable for bare chip protection of a variety of advanced packages, such as BGAs (Ball Grid Arrays), CSPs (Chip Scale Packages), PBGAs (Plastic Ball Grid Arrays) and full-arrays on LTCC (low-temperature co-fired ceramic). It’s designed to meet the “green” non-halide objectives of many technical users. Its excellent flow properties allow it to penetrate fine-pitch wires and deep cavities—without entrapping voids. A cavity or potting dam encapsulant is required for flow control. LOCTITE ECCOBOND FP4802 is formulated with an epoxy-based resin and cures when exposed to heat.
