| Summary: | While a cornerstone of modern technology, the semiconductor industry generates
substantial waste during the package production. This could pose environmental and waste
management challenges. As the world shifts toward a more sustainable future, recycling has
become increasingly important. This study focuses on the recycle of unwanted culls and runners,
which essentially are semi-cured epoxy molding compounds (EMC), generated during the
molding process. The literature review provides deeper understanding on the recycling methods
and challenges faced by the semiconductor industry. We also explore the mechanical griding of
culls and runners, followed by material characterization using the scanning electron microscopy
(SEM), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC)
techniques, etc.. An established method and proper material characterization will pave the way
for the upcycling of waste into high value applications. |
