Abstract: A TAB Grid Array (TGA) package is a package for an integrated circuit. A TGA package provides an efficient structure and method to connect a semiconductor die encapsulated in the TGA package to an external printed circuit board (PCB). The TGA package uses a tape automated bonding (TAB) technique to provide a generally flexible dielectric film bearing a pattern of conductive traces radially emanating from a die aperture to connect to an area array of pads arranged on the tape perimeter. The pads of area array of pads are connected to the TAB traces using conventional TAB inner lead bonding techniques, or alternatively, wire bonding methods, with both the semiconductor die and the TAB traces facing down towards the PCB. In one embodiment, the back of a semiconductor die and the TAB tape are attached to a stiffener via suitable bonding agents. The stiffener provides the mechanical rigidity to the package and efficiently removes the dissipated power.
