제목 | A study on the thermo-mechanical characteristics and reliability of Anisotropic Conductive Films (ACFs) according to the curing methods of epoxy resins |
초록 | At present thermal latent curing agent using imidazole derivatives has a need of high temperature and long time curing condition. In this research to solve these problems, we have used cationic initiator as thermal latent type for the curing of cationically curable resin for fast cure at low temperature. Thermo-mechanical characteristics including glass transition temperature (Tg), elastic modulus, thermal expansion coefficient (CTE) was investigated for the analysis for curing behavior. Additionally, reliability of thermal cycling and high temperature-high humidity were observed. From the results of DSC, cycloaliphatic epoxy (CAE) system using cationic initiator of thermal latent type showed faster cure property than diglycidylether of bisphenol A (DGEBA) system using imidazol curing agent. From the result of DMA and TMA, CAE system using cationic initiator showed lower CTE and higher Tg important for the high temperature stability. As a result of reliability, CAE system using cationic initiator maintained a stable contact resistance at the low temperature and fast curing condition. According to experimental result, we conformed that the curing behaviors of epoxy have great effect on thermo-mechanical properties and reliability of ACF. |
