Presentation

OEM and camera module manufacturers need to meet market demand for smaller profile, thinner and more sophisticated mobile devices. The SHELLCASE MVP solution provides the answer, offering image sensor packaging solutions that are thinner, more reliable and at a lower cost. The end result is higher device functionality and increased board capacity, which enables the next generation of smaller, smarter and faster electronics devices.
This new solution is based on Tessera’s industry-proven SHELLCASE wafer-level chip scale packaging (WLCSP) technology, which provides the benefits of reduced costs and accelerated time-to-market, without the need for modification or redesign to the image sensor wafer.

The innovative SHELLCASE MVP solution utilizes an encapsulated, glass-silicon sandwich structure to enable image-sensing capabilities through the actual packaging structure. Encapsulation of chip and interconnects provides a break-through in true WLCSP solutions.

The SHELLCASE MVP solution is offered in both cavity and non-cavity formats and leaded or lead-free bump formats. And the flexible package design and structure enable the incorporation of filters, as well as use of different package materials or processes, providing additional advantages for manufacturers.
