Establishing Robust Control for Epoxy Open Time

The Open time is called the time it takes for this chemical transition from liquid to solid. The epoxy moves into a gel state from the liquid state as it recovers, until it enters a solid-state. This article will address the development of a new, regulatory-compliant in die attach epoxy that establishes robust Epoxy Open Time control to improve the performance of product reliability with the following quality output response characteristic in Die Attach was consider; Epoxy Coverage, epoxy voids, Bond Line Thickness (BLT), and Die Shear Test (DST) strength response.
