摘要
阻焊油墨是PCB制造中所需的重要材料。随着PCB布线的高密度化、精细导线化和微小孔结构化,对阻焊油墨进一步要求其精密化、高分辨率、高感光度等方面的提高。本文通过尝试设计辅助碱溶性感光树脂开发出一款低侧蚀、高感度的液态感光阻焊油墨。
Solder resist is an important material needed in PCB manufacture. The high precision, high resolution and high sensitivity of photo-curing solder mask are required with the high density of PCB wiring, fine traverse and micropore structure. In this paper, a kind of liquid photosensitive solder mask with low undercut and high sensitivity is developed by trying to design subsidiary alkali-soluble photosensitive resin.
