摘要

The study mainly investigates the improvement of the comparative tracking index (CTI) on brominated epoxy resins in a copper clad laminate. We compare the effects of the differences in structures of various epoxy resins on the CTI. In addition, on the basis of the proportion of inorganic fillers and type, we use Pauling's electronegativity theory to find inorganic materials that affect CTI. Experimental results show that the laminate surface CTI increases as the brominated epoxy resin content decreases. When looked at structurally, epoxys modified by phenolic resin systems had lower CTI values than those modified by bisphenol A type epoxy resin systems. Analyzing the effects of inorganic filler types, we found that the ideal bromide epoxy resin proportion and the CTI value of Al(OH)(3) could exceed 600 V. (c) 2006 Wiley Periodicals, Inc.
