SHELLCASE® OP CSP
SHELLCASE® OP utilizes an innovative glass-silicon-glass sandwich structure to enable image-sensing capabilities through the actual packaging structure. The end result is a true chip size package with X/Y dimensions identical to the original die size, and a total package thickness that is same as the original silicon thickness.
SHELLCASE® OP is offered in two configurations: "face up", where the assembled die faces up towards the target image; or "face down" where the assembled die observes the target image through a port in the printed circuit board. SHELLCASE® OP has been in commercial production since 2002, and can be found in a wide variety of devices, including camera phones, digital cameras and medical devices.
