Effect of different latent curing agents on the performance of isotropy conductive adhesives and its application in LED

Abstract

The effect of three kind latent curing agents (methylhexahydrophthalic anhydride, dicyandiamide and phenolic resin) on the performance of isotropy conductive adhesives were investigated. The thermal stability, lap shear strength, volume resistivity of ECAs were tested and the reliabillity of its application in LED was also evaluated. It was found that the ECA with MeHHPA as hardner showed the best combination performance.
