Abstract

The present invention provides an acrylate composition containing a BMI resin and a use. A conductive silver adhesive is obtained by using a liquid BMI resin with maleimide as a terminal group and maleic anhydride grafted polybutadiene as oligomers, combining with monofunctional and bifunctional acrylate monomers, a peroxide initiator, a silane coupling agent and silver powder, and fully and uniformly dispersing same, and the conductive silver adhesive can be rapidly cured under the mild condition of 120°C×30 min, so as to achieve low-temperature rapid curing. In addition, a cured product obtained by the acrylate composition of the BMI resin and the maleic anhydride grafted polybutadiene has low volume resistivity, low thrust at normal temperature (23°C), good failure surface, good bonding strength at a high temperature (300°C) and good reflow soldering resistance. The acrylate composition can be applied to semiconductor device packaging, especially IC chip mounting.
