摘要:
In accordance with the present invention, it has now been found that glycidyl epoxy resins containing substitution on the epoxide ring can be used with conventional epoxy curing agents and fluxing agents to produce underfill adhesives that are suitable for use with silver-based alloys. Owing to the structural similarity of the new materials to conventional epoxy resins, physical and material properties of the invention formulations are altered little, if at all, relative to products currently in use, and so are highly compatible with existing processes.
摘要:
In accordance with the present invention, it has been discovered that the addition of organic acids provides improved performance properties to curable compositions, e.g., improved flux compatibility, improved flow properties, improved voiding properties, and the like. Accordingly, there are provided curable compositions having improved performance properties, methods for the preparation thereof, and methods employing same. Also provided are novel articles prepared using invention compositions.
