Abstract

Abstract: An o-cresol formaldehyde epoxy acrylates resin modified by cardanol glycidyl ether (EATC) was prepared and used in solder resist ink. The synthesis of EATC was studied and characterized in detail by IR spectroscopy and ¹HNMR spectrum.The coating made of modified resin exhibited good photosensitive, thermal and mechanical properties. Besides, the flexibility of the film became better. Compared to unmodified o-cresol formaldehyde epoxy acrylates resin, the solder resist ink which consist of EATC has good performance in photosensitivity. The resolution increased from 140 to 85 μm,and the minimal etching resistance decrease from 37.1 to 10.4 μm.

Key words: epoxy acrylate, cardanol glycidyl ether, solder resist ink, flexibility
