3D SDRAM Package Technology for a Satellite

Package for artificial satellite is to produce mass production for high package with reliability certification as well as develop SDRAM (synchronous dynamic RAM) module which has such as miniaturization, mass storage, and high reliability in space environment. It requires sophisticated technology with chip stacking or package stacking in order to increase up to 4Gbits or more for mass storage with space technology. To make it better, we should secure suitable processes by doing design, manufacture, and debugging. Pin type PCB substrate was then applied to QFP-Pin type 3D memory package fabrication. These results show that the 3D memory package for artificial satellite scheme is a promising candidate for the realization of our own domestic technologies.
