SEIVIOVaculub M135 Wafer thinning machine grease YesMade of high-purity linear perfluoropolyether oil, nano-level ultra-finePTFE thickens. It is refined with special anti-corrosion additives and has extremely low saturated vapor pressure, which can significantly reduce material release in vacuum environments and prevent vacuum degree drop and system pollution. It is a special precision lubricating medium specially customized for semiconductor wafer thinning equipment. It is core adapted to the high-precision, high-cleanliness, and low-volatility working conditions of the thinning machine to ensure the nano-level processing accuracy of wafer thinning.
