D/A material (B stage agent, silicone)
Shin-Etsu Chemical's B-stage material is a high-purity and electric non-conductance die-attach material which is developed for stencils or screen printing.
It shows good plate releaseablity, shape retention, and storage stability at the B stage condition (a semi-cured status that is apparently cured without tack). After bonding the chips, it can handled in the same way as thermosetting resin which is remelted by heating at high temperature. It is showed high stress resistance after curing.
In addition, Shin-Etsu Chemical's silicone die-attach material is a highly adhesive die-attach material that controls outgassing during curing and suppresses contamination of wire pads.
It exhibits a wide range of low modulus and low pollution with unique technologies of silicone, so it can be applied not only to LED but also to sensors and semiconductor applications.
