Electric Motor Reliability with Huntsman ARALDITE® Encapsulation Potting – Casting
Welcome to TECHNIQ VIET NAM
NC257MD is a no-clean solder paste specially developed for Mycronic Jet Printers, designed to provide consistent and reliable jet printing performance. It features clear, pin-probe testable residues, excellent wetting properties, and low voiding under micro-BGAs and BTC devices. The paste is optimized for use with the Mycronic AG Type Ejector, prolonging ejector life and reducing paste consumption. It supports vapor phase compatibility and maintains an 8-12 hour tack time for stable performance during assembly.
