摘要

本研究為探討藍光光碟片(Blu-Ray Disc) 保護層的製作。主要以薄
膜貼合(旋轉塗佈＋薄膜)的方式製作，使用貼合膠黏滯係數在40~60 mPa.s範圍內。調整旋轉塗佈轉速變化及抽真空時間，以有效控制光碟保護層膜厚可在92~98μm之間，並使光碟片內、外圈保護層膜厚厚差符合規範達到±1μm以內。

This study concerns the cover layer process of Blu-Ray Disc by sheet bonding. The viscosity range of the bonding glues is from 40 mPa.s to 60 mPa.s. By carefully adjusting spin speed and vacuuming time, the thickness of cover layer can be effectively controlled over the range of 92~98μm. Moreover, the thickness variation is within < ±1μm which meets the requirement of specification
