Abstract:ABSTRACT:The primary objective of this study is to emphasize the modification of the epoxy resin formulation by implementing falling weight test to discuss reduction of impact energy and apply the thesis to improve the punchability on the CEM-1 copper clad laminate. Experimental results demonstrate that the core structure can be modified with different phenolic resin; when phenolic resin PF-440 of a smaller molecular weight is used as the modified agent, the impact energy can be lowered by 17%. In addition, th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
