Memory chip packaging-an enabling technology for high-performance recce systems

Kaufman, B.

New generation airborne recce systems, for both manned and unmanned aircraft, are faced with dramatically increased performance requirements, along with calls for reduced costs, faster time to deployment, lower weight and lower physical volume. Concurrently, recording rates are moving to greater than 1 GByte/S. Thus to capture imagery for even a few minutes of record time, tactically meaningful solid state recorders will require storage capacities in the 100s of GBytes. Even with memory chip densities at present day 64 Mb, such capacities require many thousands of chips. The demands on packaging technology are daunting. This paper will consider the basis for these capacities, review approaches to memory chip packaging and offer a discussion of physical envelope trade-offs in achieving the required objective of packaging this large number of chips in a practical, flyable, cost-effective envelope.
