Electric Motor Reliability with Huntsman ARALDITE® Encapsulation Potting – Casting
Welcome to TECHNIQ VIET NAM
NC257MD is a no-clean solder paste specifically developed for Mycronic Jet Printers. It features unique rheological properties to ensure consistent and continuous deposits, reducing paste consumption and prolonging ejector life. The solder paste provides excellent wetting, bright and shiny solder joints, and minimal voiding under BGA and BTC devices. It also leaves behind crystal-clear, low-residue flux, even at high temperatures required for lead-free alloys.
