A High Performance and Cost Effective Molded Array Package Substrate

In this article we present both a relatively new and innovative family of packages that is suitable for medium pin count needs and an innovative method for fabricating the substrates for such a package.

With respect to lead count, this packaging family is positioned between BGAs and "standard" QFN with single rows of pads. The package is characterized by the extreme design flexibility in terms of I/O count, location and shape, allowing a wide range of customization only limited by PCB layout constraints.
