Die Handling Critical in Flex Electronics
Wearables require flexible hybrid electronics with die thinned to less than 30mum, and handling these ultrathin die is turning out to be a critical part of the manufacturing process.
Ultrathin die (<50 µm) have been in production for years in stacked 3D ICs. Building on this experience, NextFlex is developing new manufacturing processes that integrate ultrathin die onto flexible substrates.
