Multicore TFN700B is a no-clean, halide-free tacky flux formulated specifically for package-on-package applications. Is a Newtonian-based system; reportedly eliminates shearing conditions associated with traditional tacky flux formulations. Enables optical recognition of flux by pick-and-place systems; permits visual verification of volume before placement of the top component of the PoP. Is suitable for doctor blading and dip transfer for PoP builds. Is ROLO-classified, or non-hydroscopic and non-corrosive.
