摘要:
A one-component epoxy resin for coverage of bare chips and for underfilling of flip chips is disclosed. Two polyol components are combined in the inventive epoxy resin which decidedly improve the properties of the resin with respect to coefficient of expansion, shrinkage stress, substrate adhesion, and reactivity.
