Photoimageable composition containing flexible oligomer |
摘要 |
The invention provides an oligomer having tetraacrylate functionality which provides enhanced flexibility to photoimageable compositions which function as photoresists. The enhanced flexibility is particularly advantageous in epoxy-containing, solder mask-forming photoimageable composition, as this flexibility provides improved performance in nickel/gold plating.
