High purity epoxy formlations for use as die attach adhesives. |
| 摘要 |
<p>This invention presents improved epoxy-based die attach adhesives which are of low viscosity, high ionic purity, and stable toward thermal cycling. This improvement is obtained by including in the formulation carboxy terminated polymers which are the reaction products of polyether diols with cyclic dianhydrides.</p> |
