Abstract:
In combination, a semiconductor device and a substrate, said combination located on an inclined support member, the inclined support member being inclined at an angle in an inclined plane with respect to a horizontal plane, said combination comprising:a substrate having a front edge, back edge, first lateral edge, second lateral edge, and a plurality of electrical contact pads located thereon, the substrate being located on the inclined support member; a semiconductor device having a plurality of sides formed by a first side, second side, first lateral edge, second lateral edge, and a plurality of electrical contact pads located thereon connected to circuits of the semiconductor device; a plurality of electrical connectors interposed between the plurality of electrical contact pads located on the substrate and the plurality of electrical contact pads located on the semiconductor device, thereby at least mechanically interconnecting the semiconductor device to the substrate, the plurality of electrical connectors spacing the substrate from the semiconductor device and causing a space to be formed therebetween; an underfill material substantially filling the space formed between the substrate and the semiconductor device; a dam located on the substrate adjacent the second side of the semiconductor device for preventing flow of the underfill material for substantially filling the space formed between the substrate and the semiconductor device; and a vibrator attached to the inclined support member for vibrating the underfill material for substantially filling the space formed between the substrate and the semiconductor device.
