Abstract
Abstract An area array interconnect device (such as of the TAB type) has a plurality of input/output (I/O) leads for connection to an electronic device such as an IC. The interconnect device also has arrays of lead lines in areas remote from the I/O leads, e.g., central or internal areas, which are connected by vias to ground and/or power pads on corresponding areas of the electronic device.
