MPM Momentum Compact printer is 30% smaller overall than the standard Momentum. Equipped with the new EnclosedFlow print head option, it reportedly prints fine features such as 01005s and 0.3mm pitch CSPs with up to 50% greater volume and 25% lower deviation than squeegee blades, and paste volumes over 50% for 150µm apertures with a 0.35 area ratio. Wet print accuracy reportedly 18µm @ 6ó, Cpk>2. Configured standalone or inline. Other options include board snugging, auto paste dispenser, paste height monitor, 2D contrast and enhanced inspection, board support, and print capability verification.

NC277 VOC-free liquid flux is said to be as electrically safe as alcohol-based flux and has a medium residue suitable for long thermal demands. Withstands thermal preheats required for palletized selective soldering. Has a broad activation range, and is for use in lead-free wave soldering with tin-silver-copper, tin-silver, tin-copper, and other alloys. Reportedly has low post-process residues and can reduce preventative maintenance requirements in spray fluxing applications. Is no-clean, non-visible residue flux, but can be cleaned. Meets IPC SIR 2.6.3.7 test in an air-dried state. Sealed shelf life of nine months at room temperature.
