Abstract: A dispenser contains a chamber enclosed by an upper wall and a lower wall, both walls are oriented parallel to each other. The upper wall has a vertically bored inlet port and the lower wall has a plurality of vertically bored outlet ports for providing access to the chamber. The outlet ports are geometrically arranged in an array pattern characterized by equidistantly spaced rows and columns of bores. There is a plurality of baffle plates interposed between the upper wall and the lower wall. The baffle plates, which are spatially separated from each other, are oriented parallel to and spatially separated from the upper and lower walls. The baffle plates have a plurality of vertically bored holes for providing access between the inlet port and the outlet ports, whereby the dispenser is effective in providing homogeneous flow of fluid through the outlet ports.

Abstract: The invention is directed to a BGA package and method for making a BGA package in which warpage, delamination and package cracking are reduced. The inventive BGA package has a die attached to one surface of a substrate. The substrate may terminate at its opposite surface in an array of connection ports which is an integral part of the substrate. Alternatively, the array of connection ports is attached to the opposite surface of the substrate. The connection ports may be attach pads attached to the opposite surface of the substrate and solder balls or metal bumps attached to the attach pads. A matrix of molding compound fully encapsulates the substrate, die and the array of connection ports. The matrix molding compound is then ground to provide a flat surface and to expose portions of the connection ports. Another array of connection ports, such as an array of solder balls or metal bumps, may be attached to the existing array of connection ports.
